6 opening letter Mistakes and incompetence in the implementation of water storage projects With rapid population growth and increasing demands for water, it was deemed necessary to find additional water resources to meet those needs. Concerned authorities usually resort for this purpose to build dams and artificial lakes, exploit groundwater aquifers, build water desalination plants, wastewater treatment, etc I will, in this article, touch on the main difficulties and obstacles that many Arab countries face when it comes to storing water. After preliminary studies of the course where the water is going to be stored, a working schedule is implemented, including hydrological and geological studies of the dam s location and the area over which the water will be stored. An electric measurement of the geological layers is also conducted, test wells are drilled to have a better understanding of the nature of these geological layers and the groundwater surface level; water wells existing in the dam s basin are also studied. Several other studies are also conducted for additional data. These studies should only have a duration of one year approximately, provided they re conducted under the supervision of professional experts. The results should indicate how reliable the dam location is, and the approximate amount of water that can be stored, in addition to the right type of dam required and the relevant costs. In Lebanon, however, such studies carry on for years and sometimes decades. For example, studies to assess the storage capacity at the Karaoun dam of the Litani River s water were initiated prior to Lebanon s independence in 1943 and the dam was only completed in Technical studies for the Shabrouh dam started in the mid 1970s and the dam was only completed two years ago. Studies conducted by the Lebanese Ministry of Energy and Water for the Janna dam on the Nahr-Ibrahim river, began in the late 1960s and are still being conducted at present. The same goes for the studies concerning the storing of the Damour River water, the Ministry had completely given up on the project and if it weren t for the studies I have conducted in 1996, the project would have been completely forgotten. So what are the real obstacles behind these delays in water storage studies in Lebanon and the rest of the Arab World? These can be narrowed to two main obstacles: First, the failure to assign the right man to the right job. An individual suitable for these kinds of tasks would be a professional expert in the field of Hyderogeology. Although the concerned authorities might have among their staff hydrology and geology professionals, but what they lack would be a leading hydrogeologist who can act as the catalyst and basis for the several required study projects. With the absence of such a professional, the remaining professionals are as blind as bats, unable to fulfill the necessary tasks. The second main obstacle is the absence of monitoring and control official bodies. These institutions operate freely without any boundaries and can easily and shamelessly stall the duration of such studies year after year. The best example relating to the abovementioned would be what is happening nowadays in Lebanon concerning the storing of the Damour River s water. Although I had expressed my opposition to the project s Book of Conditions, put together by the Council of Development and Reconstruction (CDR), for it didn t include several required studies, the council went on and commissioned the project s works which yielded the expected results: The CDR failed in providing comprehensible studies that would reveal the actual storing capacity for the River s water, and the succession of flawed studies and recommendations persists Fathi Chatila Editor-in-Chief الرسالة اإلفتتاحية أخطاء في تنفيذ مشاريع تخزين املياه مع ازدياد عدد السك ان وارتفاع م عد ل إحتياجات الفرد للمياه كان من الضروري إيجاد مصادر مائية إضافية لكي ت لب ي هذه املتطل بات. ومن أهم األساليب التي يتم اللجوء إليها حلل هذه امل عضلة إقامة السدود والبحيرات اجلبلية إستثمار اخلز انات املائية اجلوفية بناء محط ات لتحلية املياه املاحلة معاجلة مياه الصرف الصح ي وغيرها. وسأتطر ق في كلمتي هذه إلى الصعاب والعراقيل التي تواجهها العديد من البلدان العربي ة لتخزين املياه. بعد القيام بدراسات أو لية للمجرى املائي امل راد تخزين املياه عنده يتم وضع برنامج عمل يشمل دراسات هيدرولوجية وجيولوجية ملوقع السد واملنطقة التي من املتوق ع جتميع املياه فوقها جس كهربائي للطبقات اجليولوجية عند موقع السد وحوضه حفر آبار إستقصائية لتحديد مواصفات الطبقات اجليولوجية وعمق سطح املياه اجلوفية دراسة اآلبار املنتشرة في حوض السد باإلضافة إلى غيرها من الدراسات التي تساهم في جالء الغوامض التي حتيط مبوقع السد والبحيرة. إن املد ة التي تستغرقها هذه الدراسات واألشغال إذا تم تنفيذها حتت إشراف أخصائيني كفوءين يجب أن ال تتجاوز سنة واحدة يتبني في نهايتها مدى صالحية موقع السد والتخزين وحت د د كمية املياه املمكن تخزينها ونوع السد املناسب للتخزين فضال عن أكالف املشروع. غير أن ما يحصل في لبنان خاصة هو أن هذه الدراسات متتد من عام إلى عام لتصل إلى عقد أو عقدين. فالدراسات امل تعل قة بتخزين مياه نهر الليطاني عند سد القرعون بدأت قبل أن ينال لبنان إستقالله في العام 1943 ولم ينته بناء السد قبل العام أما سد الشبروح فقد بدأت الدراسات الفنية له في أواسط السبعينات من القرن املاضي ولم ينته بناء السد سوى منذ عامني فقط. أما الدراسات التي قامت بها وزارة الطاقة واملياه لسد "جنة" على نهر إبراهيم فقد بدأت منذ أوائل الستينات وما زالت قائمة حتى الوقت الراهن وكذلك الدراسات املتعل قة بتخزين مياه نهر الدامور. فقد تخل ت الوزارة نهائيا عن تخزين مياه هذا النهر ولوال الدراسات التي أجريتها عام 1996 لبقي موضوع تخزين مياهه أمرا منسيا. فما هي األخطاء التي تقع فيه األجهزة املختصة إن في لبنان أو غيره من البلدان العربية والتي تؤد ي إلى إطالة أمد الدراسات العائدة لبناء السدود وتخزين املياه وي كن إختصار هذه األخطاء بإثنني أو لهما: "عدم وضع الرجل املناسب في املكان املناسب". فالرجل املناسب لوضع دراسات سليمة لتخزين املياه هو من يتمت ع باختصاص في علم "الهيدروجيولوجيا". فقد يتوف ر لدى هذه املؤس سات أهم العناصر امل ختص ة بعلم اجليولوجيا أو الهيدرولوجيا أو بناء السدود واجلس الكهربائي وغيرها غير أنها تفتقر إلى اإلختصاصي الذي ي شك ل العمود الفقري أو حجر األساس لتتمك ن هذه املؤس سات من القيام بدراسات علمية سليمة حت د د مدى صالحية املوقع الذي يتم دراسته لتخزين املياه. وعند االفتقار ملن هو ضليع بعلم "الهيدروجيولوجيا" فإن األخص ائيني املكلفني بهذه الدراسات يتصرفون مثل الضرير إذا طلب منه أن يصف الفيل. فمنهم من يصفه كاحلائط األملس ومنهم من يصفه كخرطوم طويل وغيرهم يصفه كالشجرة أو كالعامود املستدير الشكل. أم ا اخلطأ اآلخر فهو إنعدام عنصر املراقبة. فهذه املؤس سات تعمل على هواها وبدون أي حسيب أو رقيب وباستطاعتها إطالة أمد الدراسات عاما بعد عام دون أن ي شك ل لها ذلك أي إحراج. إن خير مثال على ما أشرت إليه هو ما يحصل حاليا في لبنان ويتعلق مبشروع تخزين مياه نهر الدامور. وبالرغم من إعتراضي على دفتر شروط خاص باملشروع قام مجلس اإلمناء واإلعمار بوضعه لكونه يخلو من العديد من الدراسات الضرورية فقد تم تلزيم األشغال وأتت نتائجها كما كان م توق ع. فقد أخفق املجلس في وضع دراسات شاملة تكشف حقيقة الوضع التخزيني للنهر ومسلسل الدراسات والتوصيات اخلاطئة م ستمر... فتحي شاتيال رئيس التحرير

8 feature Desalination Technology تكنولوجيا حتلية املياه BrineDis - Environmental planning, prediction, and management of BRINE DIScharges from seawater desalination plants By Tobias Bleninger 1, Sabine Lattemann 2, Anton Purnama 3, Hamdi H. Al-Barwani 3, Robert L. Doneker 4, Gerhard H. Jirka 1 The authors are currently working together in a research project funded by the Middle East Desalination Research Center (MEDRC, on the planning, design and environmental assessment of brine discharges (www. brinedis.net.ms). The article summarizes the first results presented during a workshop in November 2008 in Oman. The objective is to discuss the elaborated tools before finalizing the project with the aim to develop a modeling framework for the environmental-hydraulic design of the outfall system for desalination plants. The novelty of the work is the interdisciplinary combination of environmental issues with physical processes, discharge modeling, related plant design and regulatory issues for discharge permits. Environmental impacts The latest figures from the 20th IDA Worldwide Desalting Plant Inventory indicate that the combined capacity of all seawater desalination plants approached 28 million m³/day by the end of 2007 of which about 76% was situated in the Middle East and North Africa (MENA) region and Southern Europe, and is still strongly growing. The largest number of desalination plants can be found in the Arabian Gulf with an installed capacity of 11 million m³/day (Figure 1), or about half (45%) of the worldwide daily production. While in the Gulf region thermal processes (MSF, MED) account for 90% of the water production, the predominating process in the Mediterranean Sea is reverse osmosis (95% of all plants). Also noteworthy are the increasing plant sizes for these industrial size installations (Figure 2), such as the Al-Jubail (Saudi Arabia) MSF plant with 1.5 million m³/day capacity. But also outside the MENA region desalination is a fast growing market with hot-spots in Spain, California, Australia, and China. Figure 1: Seawater desalination capacity in the Arabian Gulf. The map shows all sites with capacities > 1,000 m³/day, the capacity by country, and the total installed capacity in the sea area (Lattemann and Höpner, 2007) Figure 2: Al Ghubrah desalination plant (largest in Oman, production capacity 191,000 m³/day): Brine waste discharge through an open channel at the beach into the Gulf of Oman (photo: H.H. Al- Barwani) Environmental impacts of seawater desalination plants are related to energy consumption and land use, but mainly to brine and cooling water effluent discharges into the marine environment (Einav, 2003). Due to the desalting process only approximately 10% (MSF) up to 50% (RO) of the intake water can be desalted, the rest is usually discharged back to the sea. In addition, desalination plants carry a number of waste products into the coastal environment (Lattemann and Höpner, 2003). Concentrated salt brine with increased temperature, residual chlorine levels, antiscalant and antifoaming additives are characteristic of reject streams from distillation plants. In RO reject streams, antiscalants as well as coagulants may be present if the backwash water from coagulation and media filtration is combined with the process wastewater before discharge. Metals from corrosion are usually found in varying, but relatively low concentrations. Copper contamination may be a concern in the reject streams of distillation plants, if copper-nickel alloys are used as heat exchangers. In addition, the reject streams, especially of RO plants, may contain harmful cleaning solutions if these are mixed with the concentrate and discharged into the sea. The environmental impacts of selected reject stream characteristics (salinity and temperature, chlorine, copper) are summarized in Lattemann and Höpner (2007). Negative effects on the marine environment can occur especially when high wastewater discharges coincide with sensitive ecosystems.

Enclosed and shallow sites with abundant marine life can generally be assumed to be more sensitive to desalination plant discharges than exposed, high energy, open-sea locations, which are more capable of diluting and dispersing the discharges. Water quality regulations Effluent discharges are usually regulated by limiting pollutant levels in the reject streams at the point of discharge (ES - effluent standards) and in the receiving environment (AS - ambient standards). By way of example, Table 1 contains the values for two chemical pollutants (copper and chlorine) usually defined in national or international regulations (here US-EPA and Worldbank standards). The ratio ES/AS is approximately 100 for copper and 27 for chlorine. The range of 5 to 1,000 is typical for most chemical as well as physical parameters, such as heat (temperature). This ratio describes the impact of the pollutants on the ecosystem, since the ES is considered to protect against acute (lethal) effects on organisms, while the AS is supposed to prevent long-time chronic influences. The ratio also expresses the necessary dilution that must be attained through physical mixing or - to some extent - through biological decay and chemical transformation processes. Table 1 Examples for effluent standards (ES) and ambient standards (AS) for two selected pollutants Pollutant example Emission standard ES Ambient standard AS ES/AS Copper 500 µg/l (Worldbank) 4.8 µg/l (USEPA) 104 Chlorine 200 µg/l (Worldbank) 7.5 µg/ (USEPA) 27 A combined approach, in analogy to wastewater discharges is proposed, which requires a regulatory mixing zone regulation (Jirka et al., 2004) that preserves the water quality objectives and accounts for the physical aspects of the mixing processes, with the following wording: The ambient standards apply in the case of point sources outside and at the edge of the mixing zone. The mixing zone is a spatially restricted region around the point source whose dimensions shall be specified either according to water body type and use or on an ad-hoc basis. A similar approach is used in the United States, the Sultanate of Oman, and other countries already. Furthermore, total allowable emission loads may be specified for certain pollutants, especially those that have a tendency for accumulating in the environment, taking the pollutant concentration and the wastewater flow rate into account. Therefore, a good knowledge of both the effluent properties and the receiving environments is required in order to evaluate the potential impacts of desalination plants on the marine environment. Mixing processes To comply with the above described regulations, modern, large capacity plants require submerged discharges that ensure a high dilution in order to minimize harmful impacts on the marine environment. Therefore worldwide, the use of submerged multiport diffusers is increasing rapidly gaining increased acceptance as effective means for the disposal of brine effluents into coastal waters. Mixing and dispersal of the discharge plume can be enhanced by installing a diffuser system, and by locating the discharge in a favorable oceanographic site which dissipates the heat and salinity load quickly. Salinity and temperature directly influence the density of the effluent. The various density differences between the brine and the receiving water represented by the buoyancy flux causes different flow characteristics of the discharge (Figure 3). The dense RO effluent flow has the tendency to fall as negatively buoyant plume and spread as a density current on the sea-floor. The effluent from thermal desalination plants is distinguished by a neutral to positive buoyant flux causing the plume to rise and to spread on the sea-surface. Figure 3: Brine discharge characteristics of desalination plants (Niepelt, 2008) For a first order of magnitude analysis a discharge calculator has been developed to compute the effluent properties (i.e. density, flow, temperature, salinity, etc.) and substance concentrations at the discharge point. The results are used to interpret the discharge situation. Two calculators have been developed. One for dense discharges, called RO-dischargecalculator, which also includes an estimation of the near-field / initial dilution in the near-field for very simplified conditions (Jirka, 2008). The other for thermal discharges, called MSFdischarge-calculator which yet does not include an estimator for the initial dilution. This is because of the variety of configurations for plant complexes, where thermal desalination is only a small part. The calculators are programmed in a MS Excel spreadsheet and available for download under www. brinedis.net.ms. Results of computations for different case-studies demonstrate the potential of the calculator to estimate the order of magnitude of expected dilutions at the discharge point and its surroundings. It furthermore allows analyzing the need for advanced discharge technologies which aim for enhanced effluent dispersion in the receiving environment and adequate discharge siting to avoid pollutant accumulation and to protect sensitive regions (Bleninger and Jirka, 2008). It also allows the interpretation of the probability of interaction with the intake. 08 Arab Water World (AWW) April 2009 / Vol. XXXIII Issue 4

12 feature Desalination Technology تكنولوجيا حتلية املياه Discharge design and modeling The previously mentioned screening equations are useful for an order of magnitude analysis, but are not applicable for the design and analysis of discharge systems. Prediction models are needed, which include the effect of ambient currents, ambient density variations (i.e. stratified water bodies), and boundary interactions, as well as different discharge configurations, including multiport diffuser designs, and surface discharges. An optimized approach has been developed by coupling two different hydrodynamic models for the prediction of either the near-field mixing (CORMIX model, and/or the transport processes in the far-field (Delft3D, The coupling procedure has been described in Niepelt et al (2008). The developed tools are in the beta-testing phase and will be available for interested people. Further details, preliminary results, such as a comparison with laboratory studies can be found on the project homepage and have been presented Thus, the system will improve the permitting process for desalination brine discharges considerably for both the dischargers and the regulatory authorities. Furthermore, the analysis improves the plant design and operational conditions by optimizing the siting and design of the intake in relation to the outfall.

14 feature Desalination Technology تكنولوجيا حتلية املياه Energy-efficient desalination technology development in Egyptian industries By Essam E. Khalil 1, and Mahmoud Shaaban 2 Water seems to be a superabundant natural resource on planet Earth. However, only 0.3 percent of the world s total amount of water can be used as clean drinking water. Man requires huge amounts of drinking water every day and extracts it from nature for innumerable purposes. As natural fresh water resources are limited, seawater plays an important part as a source for drinking water as well. In order to use this water, it has to be desalinated. Hence seawater desalination is a real challenge for Western Civilization. The base method for seawater desalination is distillation. Approximately 620 kwh of evaporation enthalpy is necessary to obtain 1 ton of drinking water. In technical installations, a multiple stage flash (MSF) evaporator is used requiring approximately 100 kwh/t (hot steam at 2 bars) and 3.5 kwh/t of electric energy for pumps. In contrast, the energy demand for reverse osmosis (RO) can be brought down to 7 kwh (large plants with pump pressure recycling and low water recovery rate) of electric energy for pump operation to produce 1 ton of drinking water with a salt content of below 500 ppm from seawater (total salt content of 3.7 percent). In small plants, however, pump pressure recycling is not applicable. In this case, energy requirements rise to of kwh/t water. In electrodialysis however, by means of ion exchange membranes, the driving force is the electric power removing the ions from the water which is to be desalinated. As the amount of electric power needed is proportional to the salt content of the water, it is impossible to give a specific required amount of electric energy. Therefore, this method is much more favorable in case of low salt contents, such as brackish water or water extracted from briny sources (heavily exploited fresh water sources near the sea) with an energy consumption of 3-8 kwh/t, than in case of high salt concentrations (energy required up to kwh/t). In case of relatively low salt contents, electrodialysis is fully competitive with regard to RO. To opt for one method or the other, the differences between both as discussed below have to be considered. Recently, seawater desalination demand in Egypt increased during 2007 and 2008 by almost 100,000 m 3 /day; this can be attributed to the vast development of industrial plants and touristic resorts. It is expected that the Egyptian market would be expanding to large reverse osmosis plant capacities; also a general increase in desalinated water production capacities is expected. The Egyptian private sector is seeking the establishment, operation, and maintenance of larger plants between 4,000 and 6,000 m 3 /day or more due to the continuous improvement of the durability and performance of modern equipment which leads to reduced power consumption by 25% in comparison with earlier models. This would contribute to green energy efforts in the country. The recent modifications of the national touristic policies encouraged business development along the north coast, in areas south of Marsa Alam and the western desert. Therefore, a larger potable water demand is expected and reverse osmosis would be the best solution to secure such water demands rather than transporting of Nile water through pipelines. The western parts of the north coast would require the establishment of at least 5 plants each of 500 m 3 /day capacity at the eastern parts of Marsa Matrouh and another 2 plants each of 1,000 m 3 /day capacity will be erected soon in tourist hotels at Matrouh. With touristic development and recreational facilities, many new golf courses are being established that would naturally require treated irrigation water. Desalination processes Table 1 outlines the commercially viable desalination processes in use worldwide today. The links from the table headings lead to descriptions of the processes. These are only general guidelines. There is no perfect process that covers all situations. For example the electrodialysis EDR schematic principles are shown in Figure 1. Electrodialysis (ED) is a process in which solutions are desalted or concentrated electrically. Salts in water dissociate into positively and negatively charged ions. The key to the ED process is a semi-permeable barrier which allows passage of either positively charged ions (cations) or negatively charged ions (anions) while excluding passage of ions of the opposite charge. These semi-permeable barriers are commonly known as ion-exchange, ion-selective, or electrodialysis membranes. The electrodialysis reversal (EDR) process was developed and introduced in the early 1970s to deal with this problem. By reversing the electric current and exchanging the fresh product water and the concentrate wastewater streams within the membrane stack several times per hour, fouling and scaling constituents Figure 1: Electrodialysis principles that build up on the membrane surface in one cycle are removed in the next reversing cycle. In addition to their significant role in desalination and water treatment, the ED or EDR processes are used in products and systems for processing food, chemical, and pharmaceutical products. Brackish Water Reverse Osmosis (BWRO), Electrodialysis Reversal (EDR), and Seawater Reverse Osmosis (SWRO) are all membrane separation processes. The product water resulting from these processes is referred to as permeate. As a rule of thumb 1-2 % of salt in the source, or feed water, will pass through the membrane into the permeate.

Multiple Effect Distillation (MED), Multiple Stage Flash (MSF), and Mechanical Vapor Compression (MVC) are all thermal processes which produce distilled water. Typically this distillate is very pure with total dissolved solids (TDS) of 1-50 PPM. Energy consumption Membrane processes normally utilize electric driven pumps as the prime source of energy but in remote locations diesel engines have been used. The thermal processes on the other hand use steam. MVC is a notable exception as this process frequently incorporates electric or diesel driven steam compressors as the primary source of energy. MED and MSF are classical thermal processes as they utilize steam from dedicated boilers, waste heat boilers or the extraction or back pressure steam from the turbines in power stations. Since all desalination processes can use some combination of energy sources and can be designed for different levels of energy efficiency, simple comparisons are difficult to make. The units for steam consumption are shown as kilograms of steam per kilogram of distillate produced. The industry norm for presenting this information is: Gained Output Ratio (GOR) = kg of distillate/ kg of steam Some smart soul in the annals of history noticed that one pound (lb) of steam has an energy content of approximately 1,000 British Thermal Units (BTU). This gave rise to the popular performance ratio, also known as economy, which is almost equal to GOR.

The present work demonstrates the significance of seawater treatment for national development in Egypt. Emphases were placed on local manufacture utilizing appropriate clean technology transfer. Comprehensive technical assessments of the different alternative routes for desalination of small and medium sized units were underway. 2. The unit size for small communities was optimized as 50 m 3 / day and its multiplication. Reverse Osmosis units are of typical units of 250 m 3 /day and multiplications. 3. The selection of the appropriate water desalination scheme was strongly based on site-oriented parameters such as salinity, low grade energy availability, pollution, demand, land cost, etc Low-grade energy sources are available as waste heat from refineries and power plants in coastal areas. For independent, environmentally clean energy, reverse osmosis is recommended particularly at low feed salinity. 5. It is highly recommended to use cogeneration principles in desalination and power generation at off-grid locations. 6. The local manufacturing of desalination units in Egypt had started with promising potentials, particularly with the Reverse Osmosis methods.

Dow Water Solutions, a business unit of The Dow Chemical Company (Dow), is dedicated to providing innovative, technology-based solutions to a broad spectrum of water needs from making seawater fit for human consumption and industrial use, to contaminant removal in municipal water supplies, to purifying industrial and residential water, and reducing and reclaiming water used in industrial processing. Dow Water Solutions is a comprehensive global provider of water and non-water treatment and separation solutions and services: Reverse osmosis (RO) and nanofiltration (NF) elements Ion exchange resins Ultrafiltration (UF) Electrodeionization (EDI) Titanium-based arsenic removal media Over the past 20 years, the company made great progress in being able to produce more water from the sea for less cost. The key success factor in achieving this goal is reducing the overall energy consumption of desalination. Dow has introduced elements with increased flow rates and significantly higher salt rejection. Because FILMTEC elements require less pressure, less energy is needed to produce more water. Other factors are at play, too, including energy recovery devices which use some of the pressure energy contained in the brine from the RO element. Through the introduction of new technologies, the cost of producing fresh water from seawater has dropped from US$ 2.43/m 3 in 1980 to US$ 0.65/m 3 in 2007, according to the Affordable Desalination Collaboration. Dow s overarching goal is to further reduce the cost of seawater desalination by 35% by These advancements are good news for countries such as Saudi Arabia, where desalination is an obvious choice for producing fresh water. Saudi Arabia is the world s largest producer of desalinated water and, while most of the country s facilities use evaporation and other technologies, the number of plants using reverse osmosis desalination is rising. تعمل شركة Dow Water Solutions منذ سنوات في مجال تأمني حلول تقنية م ستحدثة في مجاالت حتلية ومعاجلة املياه. وتهدف مشاريع الشركة مؤخرا بشكل خاص إلى تخفيض تكاليف حتلية مياه البحر بنسبة 35 باملئة مع حلول العام Refer to RIN 13 on page 88 Refer to RIN 14 on page 88 نيسان )أبريل( / 2009 مجلد - 33 عدد 4 17 عالم املياه العربي

22 energy focus Wave / Tidal Energy توليد الطاقة بواسطة األمواج والمد والجزر New wave power systems: 1.5 MW steel wave energy buoys A limitless power source to end our reliance on fossil fuels and with it, reduce the effects of global warming might sound like a dream but this is the reality on offer from the sea. It is a vast, mostly untapped, power source that could well hold the key to our energy needs in the future. UK-based Orecon, a leading company in the development of new wave power systems, has developed a 1.5 MW steel wave energy buoy consisting of three multi-resonant chambers (MRC) held in place by a gravity base which forms a tension mooring system designed to compensate for the tide, but resist movement caused by waves and increases the energy capture efficiency by more than 90%. Originally a spin-out of Plymouth University, Orecon s technology was developed by marine engineer Fraser Johnson who credits his problem-solving success to learning the hard way. Fraser said: I decided not to do A- levels and joined the Merchant Navy instead. For a number of years I worked as a Deck Officer on vessels involved in the oil and gas industry. Those vessels don t tend to carry their own engineers so when something went wrong it was a steep learning curve and extremely hands-on. It taught me more about the problems of coping with the damage caused by extreme offshore conditions than I could ever have hoped to learn anywhere else. Experience that Fraser put to good use upon completion of his Marine Engineering degree, when he opted to study for a PhD his topic of choice was wave energy systems. Fraser explained: After all my time at sea and my knowledge of the power industry, it was a subject that held a great fascination for me although I did seem to approach it from a rather different perspective to the academics around me. While they were all concentrating on creating the biggest, most technologically impressive system that would generate the most power, I looked at the mechanics already proven in the oil and gas industries and concentrated on producing a device that would actually survive the environment it was intended for. The result was the MRC a device designed from day one to be simple, robust, and to remain in operation on site for a minimum of 25 years. Simple and efficient Like other systems before it, the Orecon buoy is based on Oscillating Water Columns (OWC). However, unlike its predecessors, Orecon s device contains three 500KW OWC chambers, which, though identical in cross-section, are different in length. The result is a device significantly more efficient than earlier models, which is equipped to extract maximum energy across all seasonal sea states. Current ratings mean that each buoy will be capable of generating 1.5 MW that s enough power to satisfy 1,000 homes. Simplicity is at the heart of Orecon s entire philosophy. The 40-meter buoys are deliberately low-tech with few moving parts and none that come into contact with the water. Indeed, only the turbines and drive shafts rotate and they are housed in the machinery room contained within the structure of the buoy. The tension mooring system ensures the buoy is also kind to the environment with no continual sweeping and scouring of the sea bed. Its synthetic material tendons, already in service in other offshore structures, are highly visible to sea life and their deliberately open arrangement in the sea means larger mammals can pass freely around them without danger of being ensnared. Maintenance is made easy as well - the lack of complex mechanics means there will be no enforced shutdowns in severe weather conditions and it also has the benefit of ensuring that all maintenance work can all be carried out on site with no requirement for large, complex support vessels. Testing and implementation Final tank testing was completed in December Quarter scale models were produced to test the turbine, generator and power conversion systems and so far, say the team; the only surprises have been good ones. An early off-shore test of a scale model produced equally pleasing results and Orecon s designers are confident that MRC s components will perform well under even the most extreme conditions. Orecon signed an exclusive agreement with Dresser-Rand for the use of their unique HydroAir turbine technology for OWCs. The agreement will allow the companies to work closely together in offshore deep water with Orecon s MRC and also on shoreline with breakwater projects. By sharing their expertise the companies will provide total OWC based solutions backed up by Dresser-Rand s existing worldwide service network. Together they will be giving customers a high level of confidence in an emerging wave market that is normally only available in long established markets such as oil and gas. Orecon s first full-size buoy will be deployed, probably off the coast of Cornwall, in After further tests additional buoys will be added to create the UK s first commercial array. It s a prospect that is likely to prove irresistible to the world s energy companies as they attempt to dilute their reliance on oil and gas in favor of more renewable sources.

23 الطاقة توليد الطاقة بواسطة األمواج واملد واجلزر Wave / Tidal Energy cost of power produced from waves will be just as attractive as wind power. Where the MRC soars ahead is in power density with a yield of 100 MW of power for every square kilometer of ocean compared to around 11 MW for offshore wind power. But there are still many hurdles to overcome, not least of which is winning back the support of the UK Government. With most of the major power companies playing a waiting game, the wave industry is still heavily reliant on private investors to fund the development. It is vital work that could reap billions of pounds in the future a point made by David Crisp when he chaired London s first ever Wave Energy Summit last summer. Mr. Crisp told the conference: It is time for Government and all political parties to put real support into the industry. Political and regulatory uncertainty is a significant risk and, as such, a deterrent for investors. The Government must now send out the right signals and make real and reliable commitments to the industry. قامت شركة Orecon البريطانية الرائدة في مجال أنظمة توليد الطاقة بواسطة األمواج واملد واجلزر بتطوير عو امات فوالذية بقدرة توليد 1,5 ميغاواط من الطاقة بواسطة األمواج وهي م ؤل فة من ثالث حجرات رن انة م صم مة للتعويض عن قو ة املد واجلزر ومقاومة احلركة التي ت سب بها األمواج وزيادة فعالية إلتقاف الطاقة بنسبة أكثر من 90 باملئة. ط و رت تقنية الشركة هذه بواسطة املهندس البحري Fraser Johnson وبإمكان كل عو امة بحسب األرقام أن ت ؤ من طاقة كافية أللف منزل إذا كانت بقدرة 1,5 ميغاواط.

Mr. Crisp said: As I speak the UK leads the world in Wave Energy and we also have the best wave resources in Europe. This is a tremendous opportunity for us all it s about jobs and economic benefit in an industry we can be proud of for its sustainability. Conclusion With a team boasting almost 200 years of combined experience of working offshore, Orecon proves that the UK has the experts and expertise required to take on the world. And with 70% of our planet covered in this valuable energy resource, the battle of the waves is one, they say, that the UK can ill afford to lose.

28 industry spotlights Recycling & Water Reuse إعادة التدوير وإعادة إستعمال املياه UV technology for wastewater treatment and water reuse By Dr. Bertrand W. Dussert* In the past two decades, ultraviolet (UV) technology has received increasing attention for a variety of applications, including drinking water, wastewater, industrial, residential, aquatic, and commercial. Perhaps the largest of these applications is for treating municipal wastewater as an alternative to chlorination and dechlorination for secondary effluents, prior to discharge in the natural environment. UV continues to emerge as a preferred technology for a number of reasons, including concerns associated with the handling, transport, and storage of chemicals, as well as the requirement for dechlorination post-chlorination. A chemical-free treatment, UV is not corrosive nor poses a hazard because of accidental overdosing. capital investment of new or additional construction due to the condensed design. The systems are also easy to install into the existing pipe work, again decreasing the initial capital costs and avoiding plant downtime. This compact UV system uses powerful medium-pressure lamp technology UV is also gaining in popularity for water reuse applications. Many arid regions, especially those with growing populations such as the Middle East, are cleaning wastewater to a high standard and then reusing it for applications such as irrigation. Chlorine disinfection has traditionally been the most common method for wastewater reuse treatment, but concerns regarding the formation of disinfection by-products (DBPs) are driving a switch to other methods like UV, which does not produce DBPs. Reduced capital and operational costs with open-channel systems Capital and operational costs of units are being driven down by increasing competition and technological advances in the market. Capital costs, other than those of the initial equipment purchase, are decreasing through the benefits of smaller system footprints. Using a UV unit it is not necessary for large new infrastructure to be built to house the units, and in some cases the unit can fit into existing buildings and treatment channels. Open-channel vertical UV systems design also helps reduce operational costs. The module s top door can be opened, and the lamp can be simply pulled out. This makes the system easier to maintain and more user-friendly, cutting down on the amount of time and cost associated with maintenance. Open-channel vertical systems are also more economical to operate than horizontal systems through the increased control of flow pacing. In a basic horizontal system, flow pacing can be carried out by turning on/off the entire module or by dimming the lamps. Vertical systems allow operators to turn modules partially or fully on/off. Doing so saves power and extends lamp life. Open-channel horizontal systems are ideal for smaller flows and can be more economical than vertical systems for these capacities. They can be preengineered or custom-designed to fit into any existing space. Additionally, remote-mounted electronics enhance the installation flexibility. Compact, easy-to-install closed-vessel systems Closed-vessel systems are usually the system of choice for pressurized facilities. They are also able to offer capital cost reductions when the installation cost is critical. Closed-vessel systems are able to offer a compact design and therefore, considerable savings in space. This design feature saves on Common features of both types of systems Both open and closed systems have a number of factors in common that make UV an effective alternative to other methods of disinfection. Continuous treatment performance is critical. Systems benefit from automatic cleaning to prevent quartz sleeve fouling which, in turn, ensures optimum treatment. Multiple lamp technologies are available, such as low-pressure/high-output, lowpressure/amalgam, and medium-pressure lamps. The product can therefore be tailored to the plant s specific application needs and treatment objectives. Open-Channel Barrier VE Sunlight UV System from Siemens Water Technologies Conclusion The UV market has matured and advanced considerably in recent years. Both open-channel and closed-vessel systems are able to provide both capital and operational cost advantages over traditional chlorine treatment. 26 Arab Water World (AWW) April 2009 / Vol. XXXIII Issue 4

30 industry spotlights Recycling & Water Reuse إعادة التدوير وإعادة إستعمال املياه Sharjah parks become truly green as Bee ah brings recycling facilities to visitors Bee ah has invested heavily in making the pedestrian recycling centers available. As well as purchasing several thousand of the centers, specialized equipment has been procured, making installation by trained personnel possible in as little as seven minutes. Kevin Croucher, Director, Logistics & Procurement explained, By carefully selecting equipment and skilled people, we are able to install the centers in a highly efficient manner. As well as maximizing the speed with which we make these facilities available to the public, the reduction in installation time cuts down on the resources we use, bringing further environmental benefits. Bee ah, the Sharjah Environment Company, announced in December 2008 that its continuing expansion of the provision of recycling facilities has now brought 268 pedestrian recycling centers to several parks in Sharjah, in the UAE. The pedestrian recycling centers allow visitors to the parks to deposit their recyclable waste and contribute to the pilot recycling schemes of Bee ah. The parks where visitors can benefit from the expansion of the pedestrian recycling center scheme include Sharjah National Park, the largest park in the Emirate. Its 630,000 square meters are now served by 33 three-stream pedestrian recycling centers, making the park more environmentally-friendly as well as cleaner. In the areas that see the greatest footfall, visitors will have to walk no further than 50 meters to deposit their recyclable waste. In addition to the provision of pedestrian recycling centers, Bee ah is operating: Pilot commercial recycling schemes that have seen more than 4,000 Blue Bins delivered to offices and commercial operations around Sharjah, including at the Finance Department of the Sharjah Government; a pilot residential recycling scheme in Lagoon Tower, Sharjah; the signing of a Memorandum of Understanding (MoU) with Hamriyah Free Zone whereby Bee ah acts as regulatory and monitoring partner of the Free Zone Authority; and continued work on the improvement and development of the Al Saja a waste management site in cooperation with Emirates Environmental Technology (EET) Co. LLC. Commenting on the expansion, Samer Kamal, Managing Director, Bee ah said, It s appropriate that visitors to some of Sharjah s most beautiful areas can now contribute to the environmental health of the Emirate. We re fully confident that this phase of expansion will prove to be as successful as the first phase of the pedestrian recycling center roll-out, paving the way for a continued expansion that will see a huge proportion of the Sharjah population given easy access to the centers. Now the parks of Sharjah are green in more than just appearance. The installation of the centers follows a highly successful trial on the Buhairah Corniche, where the 130 centers are heavily used, requiring them to be emptied daily. A correct usage rate of more than 80% is on par with long-established facilities in western countries, demonstrating the desire of the Sharjah populace to play a key role in contributing to the environmental well-being of the Emirate. أعلنت بيئة وهي شركة الشارقة للبيئة في كانون األو ل )ديسمبر( املاضي أن عملياتها التوس عية امل ستمرة التي تهدف إلى توفير خدمات إعادة التدوير للمشاة قد وف رت في الوقت احلالي مراكز إلعادة التدوير اخلاصة باملشاة في الكثير من احلدائق في الشارقة. وتسمح مراكز إعادة التدوير لزو ار احلدائق برمي مخل فاتهم القابلة للتدوير في مستوعبات خاصة واملشاركة في خطط التدوير التجريبية التي تتبن اها شركة بيئة. وتشمل مجموعة احلدائق التي ي ك ن لزو راها اإلستفادة من مراكز إعادة التدوير: حديقة الشارقة الوطنية وهي أكبر حديقة في اإلمارة. ويخدم هذه احلديقة التي تبلغ مساحتها 630 ألف متر مربع مراكز إلعادة التدوير مكونة من 33 خط في الوقت الراهن ما يجعل احلديقة أكثر حفاظا على البيئة مع احلرص على نظافتها في الوقت ذاته. وفي املناطق التي يزداد ترد د الناس عليها ي طلب من الزوار املشي ملسافة ال تزيد على 50 متر لرمي مخل فاتهم القابلة للتدوير.

32 industry spotlights Recycling & Water Reuse إعادة التدوير وإعادة إستعمال املياه Innovative reuse technologies address growing demand for water The world s population is expected to increase dramatically between now and the year With this growth will come an increased need for water as well as an increased wastewater production. With many communities throughout the world approaching the limits of their available water supplies, the water and wastewater industry is turning to a variety of innovative technologies to help conserve this precious resource. Water reuse is increasingly being used as a method for conserving and extending available water supplies. Independent research studies project over a 150% increase in global water reuse capacity from 19.4 million cubic meters a day in 2005 to 54.5 million cubic meters a day in A majority of the additional capacity will involve tertiary treatment (e.g., natural systems, disinfection, filtration and coagulation/ filtration) or quaternary treatment. The remainder, predominantly in emerging markets, will involve secondary treatment only. Among tertiary filtration technologies, deep bed media filtration demonstrates a strong record of performance in the United States and other countries. One technology, the TETRA DeepBed filtration system from Severn Trent Services, is a down-flow unit that features a gravity sand filter. The system achieves excellent retention of solids at high hydraulic and solids loading rates, does not require the effluent to be prescreened and can be readily switched on and off to optimize operating costs. Its high-efficiency backwash process maximizes solids release after a single operation with virtually no media loss. In the United States, the state of Florida s wastewater treatment plants and water reclamation facilities so often select the TETRA DeepBed system that 12 of the last 15 winners of the Florida Water Environment Association s Earle B. Phelps Award in the advanced water treatment plant category have used the system. In China, where the Central Government has recently enacted a number of measures to manage natural resource consumption and reduce environmental degradation, the TETRA DeepBed technology is being used in several new wastewater treatment facilities. For example, a TETRA system in China s Zhejiang province was part of a pilot test of a patented three-stage biofiltration process in which the system is preceded by an up-flow submerged denitrification filter reactor and a submerged aerated filter reactor. During the two-month pilot study, average BOD was reduced from 200 to 2mg/L, NH 4 -N from 82 to 3 mg/l, T-N from 88 to 112 mg/l and TSS from 165 to non-detect. In Australia, Severn Trent Services has been awarded a contract to supply TET- RA Denite biological denitrification filters for Stage 1A of the Bundamba Advanced Water Treatment Plant the first stage of the Queensland Government s Western Corridor Recycled Water (WCRW) Project. The six-step treatment process used at the advanced water treatment plant involves removing the nutrient concentrate. This will provide environmental benefits by lowering the amount of nutrients that are currently discharged from the wastewater treatment plants into the region s waterways and Moreton Bay. Precipitation and clarification processes will remove phosphate, and TETRA Denite biological denitrification filters then remove nitrate. Together these steps will lower total phosphorous and total nitrogen in the waste stream. ي توق ع زيادة عدد سكان العالم بشكل ملحوظ من اآلن وحتى العام 2020 مم ا سيزيد الضغط على موارد املياه وسيدفع مبعظم الدول إلى إعتماد تقنيات جديدة لتأمني املياه كإعادة إستعمالها. وت ؤم ن Severn Trent أنظمة TETRAللترشيح DeepBed في هذا املجال وتقوم بتركيبها في عدة منشآت حول العالم. Niagara closed-loop, evaporative wet surface air coolers conserve water Niagara Wastewater WSAC Niagara designs and manufactures Wet Surface Air Cooler (WSAC ) closed-loop, evaporative coolers and condensers as a cost-effective technology for both heat transfer and water conservation. Used in a wide variety of industries, applications for these WSAC coolers and condensers include fluid loop cooling, direct vapor condensing, hydrocarbon de-superheating, and subcooling. The system enables reusing low quality water to condense steam The use of WSAC systems may reduce the amount of water required in a plant due to the ability to use low quality water as spray makeup. Commonly used for adding capacity in thermally challenged plants, WSAC coolers and condensers offer additional direct cooling without having additional tower capacity or makeup water. The basic principle of WSAC technology is that heat is rejected by means of latent (evaporative) heat transfer. Warm process fluids or vapors are cooled in a closed-loop tube bundle. Open-loop water is sprayed and air is induced over the tube bundle resulting in the cooling effect. The process fluid being cooled never comes in contact with the environment. Due to the closed-loop design, spray water never contaminates the process stream and higher cycles of concentration can be achieved.

34 industry spotlights Groundwater Development تطوير املياه اجلوفي ة The different techniques of traditional catchment of water for the Algerian Sahara By Bensaada M. and Remini B.* The Algerian Sahara is a vast desert covering more than three-quarters of Algeria s land, it includes several sandy terrain, including extensive dunes. For centuries oases were covered with a series of ingenious techniques for wells and springs that captured the underground galleries (foggara), extracted or drained local groundwater, thus ensuring a permanent supply of water while minimizing costs and considerable animal backtracking for water (wells pendulum, pulleys, noria). The water is collected in reservoirs; dispatcher-shaped comb divergent channels (séguias) distribute water in the oasis. Each cultivated plot is surrounded by ditches; the water gets under a stringent regulation, which sets the time and the duration of the water tower. Engine pumps have helped increase the extraction of and tapping into deep artesian, and sometimes non-renewable groundwater. Ghouts The wells A well is often associated with the technique of drawing that accompanies it. In developing countries, there are still wells with pendulums, well pulleys, coupled with an animal or motor, and wells with gear wheels operated by the circular movement of a workhorse. To supply water nowadays, wells are often used with a pump placed at the bottom of the shaft or at the top. Wells used for irrigation in the Sahara can be reduced to two basic types: The well-pulley and animal traction, and pendulum wells. A third type is the shaft pulley and human traction (kerka or aghram). a) Animal traction wells Animal traction wells are characteristic of the Mzab oases, with depths ranging from 10 to 60 meters. The wells can be constructed with the use of stone and masonry to withstand the drawing of the device. The type of sink for these wells is not exclusive of Mzab, it extends to the shore of Laghouat, the Sahel area of Tunisia, and to the Djerba area in Libya. This same system exists across the central Sahara, with variations that relate to the materials available, the nature of aquifers, and the depth of the water. b) Pendulum wells A pendulum well is essentially a rotating lever around a set of two wooden bars, brick or masonry. The lever is made from a palm tree trunk, sometimes two poles made of tamarisk wood slide so as to track changes in the water level. At one end of the short arm, a counterweight is fixed; on the other end hangs a utensil which serves as a water bucket and distributor. The well is maneuvered by hand; pulling the rope attached to the suspended bucket enough to counterbalance the rise. The flow of a single well is always lower than that of a well with animal traction. The ghouts In some regions of the Algerian desert, on the periphery of the great ergs in the East where the water table is near the surface, a method is used to transform a massive area into a constellation of gardens. Seen from the air, the city appears fraught with deep excavations of about fifteen meters, they are planted with palm trees, with tree tops that come out only at ground level. This method of planting is characteristic of the Oued Souf region: The ghout which designates the toilet, the funnel, and the manmade hole. Ghouts have the advantage of reducing evaporation. The foggara South Western Algeria is characterized by an irrigation system called foggara delivering water to palm trees. The foggara underground canal has a very slight angle which draws water to the surface under the effect of gravity from the aquifer area beneath the hills upstream to the driest land located downstream in the direction of the palm trees. It has a section gallery of variable drainage, typically 50 to 80 cm wide, and 90 to 150 cm in height, and a series of wells spaced at 12 meters. The principle is simple if the topography of the region has a terrain causing a change in the profile of piezometric unconfined aquifers, local aquifers that do find outlets in low-lying areas. The waterworks of the foggara a) The gallery At the exit of the foggara, water is divided by a stone comb that is soft and easy to scratch, it is the main kasria. The latter must have a sufficient number of openings where water can easily escape without turning back. These openings allow the water to flow into gutters or channels which can be further divided by another comb and sofor in all directions towards the palm trees. b) The main kasria It is a triangular-shaped basin helmed by a large comb, playing the role of water stabilizer. This technique consists in calming water before its distribution. The main kasria receives the entire flow of the foggara also called the kasria-lak bira. This divides the flow of the foggara usually into three, four, or five big ditches (mjara). From that pool, the channels will range in all directions to the plots designated for irrigation. After these mjara, kasria on the other side divide the water. c) The secondary kasria It is a new basin found after the first, this basin is characterized by being shared among families from each tribe or group involved in carrying out the foggara. d) Minimal kasria Others are minimal kasria along the different routes depending on the need. These kasria come after the secondary distribution, they lead water to madjens. 32 Arab Water World (AWW) April 2009 / Vol. XXXIII Issue 4

35 أخبار صناعية تطوير املياه اجلوفي ة Groundwater Development The main kasria e) The Madjen It is a shallow rectangular watershed for recovery and adjustment, which is situated at the top of the garden where water accumulates for twenty four hours. Irrigation is carried out usually in the early morning in the summer, and a little later in the morning in the winter. Each garden has a built clay or concrete madjen in order to avoid unnecessary wastage of irrigation surplus. Currently some foggaras are abandoned (due to the problems of collapsed galleries and the locations of drying wells, etc ). The rest of foggaras saw their rates reduced over time as is the case of M ghaer and most of Timimoun. Conclusion The techniques for controlling groundwater in the Sahara are an example of very rational use of natural resources. People that run oases through these techniques learned from the observation of the surrounding natural environment, and have applied the lessons learned by imitating nature and sometimes even improving it. These techniques do not cause erosion or salinization of farmland. Today, we are witnessing a sharp devaluation of local know-how that seems to have little chance of success at the technical level.

36 industry spotlights Groundwater Development تطوير املياه اجلوفي ة The method of operation determines the quality and quantity of water harvested from groundwater wells By J Andrew Reid* The groundwater well has been with us since ancient times and has allowed mankind to populate areas where surface water is not available. Though the design and construction of wells has changed and technology has produced pumps with amazing capabilities, the aquifer that supplies the well remains the same. We have become so fascinated by pumping technology that we have lost sight of the natural mechanisms that produce the potable groundwater we seek to harvest. Nature s way A virgin aquifer has little exposure to the atmosphere since its contact with the surface is through springs and bleeding fractures that are under positive pressure most of the time. When we begin drilling wells into the ground we create connections to the atmosphere that did not exist previously. These connections have minimal effect when the well is pumped at a rate that is less than well yield because the water level in the well remains fairly high. When low yield wells are operated using standard pumping systems they are frequently over-pumped. This turns the wells into breathing holes that draw in air as the water level is drawn down and then slowly expel it as the water level rises. Overpumping empties the geology around the well, changes the direction of flow within the aquifer creating inflow at submerged outflow points, accelerates water movement picking up particles that had settled out and introduces oxygen. All of this activity in a natural infrastructure that normally produces potable water as a result of long residence time in a cool, dark place that is devoid of oxygen where water moves at a snail s pace. Our current method of collection works against the natural mechanisms by which freshwater aquifers produce potable water. Wells influence aquifers Every well that is pumped has some influence on the surrounding geology. As the pump draws the well down, nearby water flows in draining the ground around the well while distant water moves in slowly to replace that which entered the well. The difference in rate of travel results in a dewatered area in the shape of a cone in the aquifer around the well. This cone of depression is deepest at the well and shallower as you get further from it, growing in depth and diameter the longer and harder the well is pumped. Once pumping ceases the depression slowly fills in as water from a distance moves toward the area of lower pressure that is the cone of depression. The cone influences water movement through the aquifer so its existence creates a zone of influence. When water is withdrawn slowly from an aquifer the well s influence is minimal and the only contaminants that are likely to affect it are those directly upstream but over-pumping increases the radius of influence and results in reversing the natural direction of flow in the aquifer. Pumping hard can draw water from 360 degrees around the well, bringing contaminants such as brine from nearby bodies of salt water, nitrates and pesticides from adjacent farm land, surface water from streams, leachate from landfills and trash pits, and leakage from underground storage tanks to the last place you want it: Your water well. 34 Arab Water World (AWW) April 2009 / Vol. XXXIII Issue 4

37 أخبار صناعية تطوير املياه اجلوفي ة Groundwater Development Improving water quality Looking at the well/aquifer relationship in this way we quickly realize that the quality of water harvested can be affected by the rate at which we pump water from a well. If you examine a water test report you see that most of the contaminant levels listed are expressed in concentration per unit of volume; mg/l, ppm, etc. When we pump hard and create a cone of depression that dewaters the area and draws contaminants to the well, concentrations are likely to be higher than when we harvest at a rate that is more in line with natural aquifer flows. This is a picture of the San Joaquin Valley southwest of Mendota in the agricultural area of California. Years of pumping groundwater for irrigation has caused the land to drop. The top sign shows where the land surface was back in 1925! Compare that to where the man is standing (about 1977) The table at the right compares two water tests taken from the same low yield well. The test sample from May 2008 was taken when the well was harvested using a submersible pump feeding a captive air pressure tank. This arrangement over-pumped the well constantly and caused the owner to run out of water regularly. The second test in December 2008 was taken several months after a time control was installed to run the existing well pump for a couple of minutes several times an hour to fill an atmospheric tank with booster pump. The second test showed a remarkable decrease in the concentration of many test parameters. The cone of depression was eliminated so the well ceased to be the center of attraction and with the volume of water up in the well and surrounding geology, the dilution rate was also higher. The result was a much improved water test. Arsenic in groundwater is one contaminant that has been a topic of concern in the US and abroad. The current US Federal limit is 10 ppb (parts per billion) but some local jurisdictions have already adopted a lower 5 ppb limit for drinking water. Arsenic exists in nature in combination with other elements like iron or sulfur in the form of various naturally occurring compounds. Many experts are convinced that it is the oxidative breakdown of these mineral compounds that is a major cause of arsenic release into groundwater. Natural changes in the water table can result in some mineral oxidation but over-pumping can make the situation worse because it leads to increased oxygen levels in the water around the well and exposes the geology in the cone of depression to air drawn in when the well is pumped down. Arsenic bearing minerals in that geology can be made soluble by oxidation and picked up in the water when the cone of depression fills back in after pumping ceases. In addition to oxidizing mineral the cone of depression also raises the concentration of arsenic per unit of volume in the same manner discussed above. It is beginning to appear that the unacceptable level of arsenic in well water may be another unintended consequence of over-pumping. Over-pumping causes well and aquifer damage The negative effects of over-pumping can be cumulative and lasting. When an aquifer is over-pumped the result can be the spreading of contamination or even land subsidence. Subsidence is the settling of ground and it has been shown that more than 80% of the subsidence in the United States is related to the withdrawal of groundwater, a phenomenon that is reported elsewhere around the globe. When land subsides, it is compacting. The spaces in the ground are closing and therefore the ground sinks or subsides. These spaces contain the groundwater that makes up the aquifer so once they disappear the aquifer s ability to store water is reduced forever. A long rainy season or good snow melt is not going to recreate voids that have closed. When a well is over-pumped, water is withdrawn faster than it is coming in. This results in a dramatic drop in the well water level and the geology around the well drains. The longer this goes on the more widespread the dewatered area is. When the nearby cracks and voids are emptied of water they may collapse if they are not self supporting. This phenomenon can be seen in hydrofractured wells that suffer from diminishing yield. Though many hydrofractured wells show an increase in production, it is often not enough to convert them from low yield to great producers. When a low yield well is pumped by conventional means there are times when it is pumped quite low. If the level in the well is lowered to the point at which the fractures opened by hydrofracting are exposed and draining, they can suffer from subsidence. The water was the wedge that created or widened the fracture and has been helping hold it open. Once the wedge is removed the fracture can slowly close back up decreasing yield and increasing the frequency of عالم املياه العربي 35 نيسان )أبريل( / 2009 مجلد - 33 عدد 4

Even in the short term over-pumping can result in decreased well yield. The only real difference between a dewatering operation and water harvesting is the way the well is operated. Over-pumping is what causes the cone of depression around a well and dewatering is simply extended over-pumping. The longer over-pumping goes on the larger the cone of depression becomes. The deeper and wider the cone, the smaller the interface between the well and aquifer and the poorer the well yield will be. The result of over-pumping is dewatering, not a good way to insure the sustainability of a well or an aquifer. Get more by pumping less Recently a client asked us how to get more water from the two 900 wells that fed a 4,200-gallon (15,900 liters) buried storage tank used to supply his irrigation system. The well pumps ran continually trying to keep up with the irrigation system s needs but were failing to do so. When it was suggested that he would get more water by running the pumps less he thought we were insane. It took a great deal of convincing but in the end he installed a control system that pumped the wells at timed intervals based on their yield capability to avoid over-pumping. The end result was that the 4,200-gallon tank now fills in 1/3 the time and the same wells are easily keeping up with irrigation. Now, you may be wondering, how this could be? The explanation can be found in a combination of factors. First, the well pumps are delivering more water now because the wells are running nearly full and the pumps do not have to lift the water from 800 feet (244 meters). Second, the well yield is increased because the client is no longer dewatering the area and reducing the well s interface with the aquifer. Of course, since the pumps run a lot less, his electric bill is also reduced dramatically. This demonstrates that when withdrawals are in step with the rate at which the aquifer functions the well produces more water over time. When pumping is in excess of the transmission rate the operation changes from water harvesting to dewatering and well yield begins to decline. Over-pumping threatens a well s longevity not only through subsidence and dewatering but also through mineral and biological buildup. Wells are susceptible to loss of production from clogging caused by sediment and buildup of mineral crust or bio-slimes. The repeated exposure of the well walls to air hastens the development of these problems which can seal the well off from the aquifer. Change is needed Though many are beginning to agree that over-pumping is the number one cause of well failure and there is reason to believe it causes the other problems discussed, the topic has not received the attention needed and few have taken concrete steps toward the prevention of over-pumping. There are some commercial enterprises marketing equipment and promoting environmentally sensitive groundwater harvesting like John Dartnall of the University of Sydney, Australia, who has been working on low volume pumps that install easily by hand and run on 40 to 60 watts of power. Dartnall s pump can be run on solar power, grid electricity, gas, propane, or even human power and can be adjusted to various pumping rates. These pumps are made to run continuously until an atmospheric storage tank is full and have been in use in Australia for ten years. In the United States, Reid Plumbing Products, LLC has been using its Well Manager time-based pump controls to increase the amount of water that can be harvested from wells without over pumping. This approach works with any well and pump combination powered by electric or solar power and has been used to either maximize production or limit it to the water rights of the owner. These systems have been used successfully in North America for the last 15 years. When a natural infrastructure is operated in a way that ignores all of the relationships that make it function, we should not be surprised if results are less than desirable. Sir Francis Bacon ( ) put it most elegantly when he said Nature, to be commanded, must be obeyed. If we expect to continue using aquifers as a source of potable water we must work within the natural parameters by which they function. Bigger, more powerful pumps will not produce the result we need, but adapting our methods to work with nature will. Slow and time-based pumping will allow the use of poorer aquifers more than we thought possible and relieve the stress and associated problems currently caused by over-pumping.

40 industry spotlights Groundwater Development تطوير املياه اجلوفي ة Nanoparticles offer promise in groundwater remediation says Rice University researcher Nanotechnology, the science of matter on the atomic scale, offers much promise for making water clean and safe for the world s citizens, but care also should be taken to study possible unwanted environmental side effects, says researcher Vicki Colvin, Ph.D., of Rice University. Colvin s presentation, Nanotechnology in the Environment: Clean Water from Small Materials, explored the emerging science of nanotechnology at the National Ground Water Association s Ground Water Expo and Annual meeting recently. golf clubs, crossing many industries, Colvin said. The question is, do they find their way into aquifers and are they going to be part of drinking water systems? The same qualities that make nanoparticles so useful and effective can also present dangers to the environment. Small amounts in mass could be huge amounts in surface area so that you could moderate and change environmental processes drastically, she said. Among the potential issues: Nanoparticles could facilitate the transport of contaminants The reactive properties of some nanoparticles could create unwanted byproducts At its atomic-scale size, nanoparticles could invade and affect biological organisms in ways larger particles cannot They could persist in the environment for a long time. A nanoparticle is 1 to 100 nanometers in diameter a nanometer being one billionth of a meter in length. While some nanoparticles occur naturally, nanotechnology has resulted in the development of nanoparticles that have very specific properties. In the context of remediating contaminated water, two such properties are: For all those reasons, we want to be cautious with them. The science of application of nanoparticles has been around for 10 years or longer. What s newer and less evolved is the science of how to deal with the unwanted consequences, said Colvin. This evolving science is complicated by the fact that it can be difficult to differentiate between naturally occurring and manmade nanoparticles. Sequestration, where the nanoparticle locks up a contaminant to where it s not harmful, and Reaction, where a nanoparticle reacts with another substance to render it harmless. The real benefits to groundwater are all related to the surface area of nanoparticles. A gram of nanoparticle material might have the surface area of a football field. Nanoparticles have huge surface areas for reaction and sequestrations, Colvin said. Another advantage to nanoparticles is that they are so small they do not settle in water but are a part of the water flow, thus facilitating their ability to react with or sequester contaminants. Colvin said the ability to design and produce nanoparticles to do very specific things is so good that you can make a nanoanything these days. The field of nanotechnology is projected to be a US$ 1 trillion business in the next five to 10 years. They are in many consumer products from deodorants to sunscreen and car tires to My take-home message is that nanoparticles are already out there in nature. People already are dealing with them and don t know it, she said. And, we don t want to make the same mistakes as in the past by introducing technologies that create problems.

41 أخبار صناعية األنابيب وأجهزة كشف التسر ب Pipes & Leak Detectors Active leakage control in low pressure situations Is it possible to carry out an active leakage control strategy using traditional methods and equipment when pressures are extraordinarily low? Leaks make noise or acoustic sound because the pressurized water forced out through a leak loses energy to the pipe wall and to the surrounding soil area. This acoustic sound, depending on the material of the pipe work either dissipates over a long distance or is absorbed very quickly into the pipe wall. In metallic or hard walled pipes, the sound transfer is extremely good and in non metallic or soft walled pipes, the transfer is extremely bad. Other considerations are pressure and size of the orifice. The higher the pressure and the smaller the leak, the greater the noise or energy is created and this can be reduced depending on the orifice size or pressure. Table 1 shows what is ideal for leakage location or detection. Leak Noise Factors Factors producing good quality Factors producing poor quality leak noise leak noise High water pressure Low water pressure Hard backfill Soft backfill Small rupture Split mains Clean pipes Encrusted pipes Metallic pipes Soft/Lined pipes Small diameter pipes Large diameter pipes Case study - Hanoi The initial water balance as well as the measurements in the five pilot areas indicated very high levels of leakage. It was uncertain which percentage of the existing leaks could be detected given the extraordinarily low pressure (6.6 m average pressure system-wide). The leak detection was carried out between 23:00 and 04:00 during the period from October 2007 to February The equipment used included: Listening stick, stethoscope, ground microphone (Gutermann Aqua Scope 3), leak noise correlator (Gutermann Aqua Scan 610), and advanced noise loggers (Gutermann Zone Scan 800). Hanoi has carried out a large-scale pressure monitoring program on about 140 points on transmission, distribution, and service lines. The weighted average pressures observed were: Transmission lines: 9.0 m Distribution lines: 7.4 m Service lines: 6.0 m The system-wide weighted average was calculated to be 6.6 meter, +/- 10%. Pilot areas were selected in different parts of the distribution system. For each of the five pilot areas, data was collected which comprised of length of distribution, service lines and number of service connections. Flow and pressure data was collected for each of these regions over a 48-hour period. The period was restricted to this time as low pressure was being experienced in adjoining systems, preventing a permanent DMA from being established or extending the measurement period. Summary of findings during leakage survey By Stuart Hamilton* Another leaking meter A mixture of approaches was decided to see which ones could be used within a low pressure system and to ascertain if acoustic equipment can be used in low pressure areas with different service and mains materials. Decisions for the methodology of Active Leakage Control (ALC) were originally made from studying the distribution system plans. It was clear that the ALC methodology had to be different for each area to obtain best results from the equipment; this was mainly dependent on the pressure available, the material of pipe work, background noise level, and the availability of fittings. Here, we will discuss pilot areas 1, 2, and 5. Area 1 The leakage model indicated that there might be up to five ESPBs (Equivalent Service Pipe Bursts) after adjustment for pressure. For area 1 it was decided that all fittings should be listened on for audible leak noise. However, it was quickly realized that there was a distinct lack of visible service connections to enable ALC to be satisfactory completed. This is a major problem in ALC and it can be assumed that a number of small leaks may have been missed. The noise transfer from the leaks within the distribution system was very poor and can be accredited to the service pipe and mains material which in certain areas was found to be polythene. The quantity of polythene pipes in this area is unknown. When a leaking service was located, the noise transfer from the ground close to the leak was very good and the leak noise was clearly audible. However, when listening on the water meter some 0.5m away from the leak position, the leak noise was barely audible. When this leak was excavated, it was found that the service pipe was black polythene. The only feasible way of detecting all leaks in a situation like Area 1 will be to carry out a comprehensive ground microphone leak detection survey listening to all distribution mains and service connections, keeping the distances between contact points as short as possible. Any other acoustic methodology may be unsuccessful due to the distinct lack of fittings, be it distribution mains or service connections. Area 2 The leakage model indicated that there might be up to 19 burst after adjustment for pressure. This was deemed as the oldest and the most problematic of the five chosen areas due عالم املياه العربي 39 نيسان )أبريل( / 2009 مجلد - 33 عدد 4

No other ALC method was used in this area i.e. sounding of services. AquaScope 3 training with Hanoi Water to its age, service connection material, mains material and usage. The methodology of ALC in this area was to listen on all services with a listening device of both electronic amplified and non electronic types. This method was chosen as the deemed approach as there were only a small number of mains fittings available and a large number of suspected leaks in the area. It was not known at this early stage if the leaks were present on service connections or distribution mains. Noise loggers were deployed on the valves that were present within the distribution system and with success as they indicated an area where a leak could be present. This area was investigated and the leak was located and repaired. More success would have been possible but with the low number of valves within this area not enough coverage was possible. A large number of leaks were found in area 2 between that of the communication pipe and supply pipe. The majority of the property/private (supply pipe) side leaks located were that of open taps (could not be closed), leaking joints, homemade repairs or just general deterioration of the pipe work where no good metal was left within the galvanized iron pipe work. Nearly all the leaks that were found on the communication pipe work were that of deterioration of the pipe work where no good metal was left within the galvanized iron pipe work or on joints. Area 5 The leakage model indicated that there might be up to 5 bursts after adjustment for pressure. It was after viewing the distribution network/plans for this area that it was decided that noise loggers could be tried on this distribution system. The noise loggers were deployed and left in situ and downloaded each morning to view the reports of where leaks may be present. On each download occasion, a leak position was clearly indicated on the sluice valve closest to the water meter. This was thought to be the meter causing the noise and was ignored on the first night reading. On the second night, this was much the same and was investigated during the early hours of the morning to see if a leak is present or not. A leak position was located with the use of the electronic listening device and the ground was marked for excavation. On the following day, the ground was excavated and a leak was located and repaired on a 63mm polythene service/main. Several excavations had been made in this vicinity in the past as the water was seen to be running from the ground, causing problems. The position was logged again with the noise loggers and the Conclusions Leak detection The most important conclusion of the trial leak detection campaign is that it is possible to detect leaks in the Hanoi water distribution network using acoustic equipment. It should be noted that the trials were conducted by a fully trained engineer and it cannot be assumed that the same results could be obtained by a non-trained member of staff. This trial has demonstrated that using acoustic technology, with the help of an experienced engineer, leakage detection can be achieved in areas where the night time pressure does not reach 10m. However, experiences from this trial show that not all techniques work in every situation and that the correct method of approach should be used to gain maximum benefit. Data collection Electronic listening stick Electronic technology like the one used for this trial is very easy to use for both the experienced and non experienced engineer. The Aqua-scope 3 used in Hanoi had a numerical display which indicated the level of noise, thereby eliminating the limitations of human hearing. Ground microphone The ground microphone is mainly used for leak pinpointing this means to finally decide the exact location of the leak (for excavation) after it has been localized by any of the other methods. Leak noise correlator Leak noise correlation on soft walled pipes i.e. non metallic pipes is generally not as effective as on hard walled pipes i.e. metallic pipes. Hence, only short distances must be kept between the two sensors up to a maximum of 60m and this is depending on the pressure within the distribution system at the time of correlation. Due to this problem, in many areas in the Hanoi distribution network, where there are (i) plastic pipes and (ii) a lack of access points to the network, the use of correlators will be limited. A successful correlation was possible in Hanoi where the correlator was used to locate a leak on a 200mm PVC main over short distances (maximum of 60m at 10m pressure) during the early hours of the morning between 2am and 4am.

Leak noise loggers The biggest surprise of the leak detection trial was that leak noise loggers worked well despite the extraordinarily low pressures. However, a serious problem for the large scale use of noise loggers is the lack of access points to the network. In the future, if access points were made available, such as fittings in chambers, valves and underground hydrants, then the use of noise loggers may become more common. Permanently installed leak noise loggers may not be an option, labor being cheap. However, it must be considered as new technology now allows for remote reading of the loggers giving a 24-hour report on the state of the distribution system. Refer to RIN 39 on page 88 Leaks located A total of 19 leaks on service connections were reported and repaired. However there was one leak that has to be accounted for and one big leak on a service line was detected bringing the total to 21. In addition, an even larger number of smaller leaks before and after the customer meter have been found. Some of these were so minor that repairing them was deemed uneconomical but 12 were deemed large enough to report for repairing. Quantification of leaks has been tried but with the low level of confidence in the flow or DMA data, this may not be totally accurate *Stuart Hamilton is secretary to IWA s Water Loss Task Force and is leading an initiative on acoustic leakage detection techniques and methodologies.

44 industry spotlights Pipes & Leak Detectors األنابيب وأجهزة كشف التسر ب HOBAS for a Blue Danube In Hungary s capital Budapest 600,000 m³ of water run into the Danube daily, 51% of which are completely untreated. This does not only endanger the area s wildlife but also conflicts with the objectives of the Sofia Convention in 1993 to protect and sustainably use the Danube. HOBAS CC-GRP Pipe Systems are absolutely leak tight, long lasting, have excellent hydraulic and long-term static properties. Their handling and installation is remarkably easy due to their light weight, simple push to fit couplings, and compatibility with other materials. These advantages and numerous industrial projects successfully realized with HOBAS in the past, convinced the client to utilize HOBAS CC-GRP pipe systems for further parts of the treatment plant: A twin line DN 1200, SN 5000, PN 6 leads to the plant from the west and another two paralleling pipelines DN 1400, SN 5000, PN 6 come from the east adding up to a total length of around 2 km. Around 2 km of HOBAS pressure pipes were utilized to build Europe s second largest treatment plant Already in 1974, a program with the working title Sewage Treatment and Disposal for the capital Budapest was set up envisaging the establishment of 4 wastewater treatment plants in Budapest. The first is the Budapest Central Sewage Treatment Plant (BKSZTT) that was planned to be built on the Danube s island Csepel. Budapest Central Sewage Treatment Plant is the biggest environmental investment in Europe. No efforts and costs were spared concerning architecture and landscaping, so that the plant, which will be commissioned this year, harmoniously blends in with its surroundings. A bypass with short pipes and a loose collar joint were installed in the plant building for an inductive flow meter The project is financed by the EU from the design to construction and a first feasibility study was made by a consortium lead by the Swedish engineering company SWECO in Latest technologies will increase the efficiency of biological treatment by three times and enable 92% of wastewater to be treated biologically. With a planned maximal capacity of 900,000 m³ per day, it is the largest sewage treatment plant in Hungary and the 2 nd largest in Europe. It will easily cope with the current 350,000 m 3 sewage coming from the area s main. This covers approximately half of Budapest s stormwater and wastewater originating from households and industry. Located on a floor space of 29 hectares in the north of Csepel, the sewage treatment plant lies between km 1641 and 1642 of the Danube. A bypass with short pipes and a loose collar joint was installed in the plant building for an inductive flow meter. HOBAS CC-GRP Pipes were selected for this thanks to their relatively light weight, distinguished chemical resistance, and excellent hydraulic characteristics. The line consisting of three standard length (6 m), one 4.5 m and one 1.5 m long HOBAS CC-GRP pipes was fixed on suspensions. A connection pipe with a mechanical coupling was inserted prior to the flow meter. قامت شركة HOBAS بتأمني أنابيب CC-GRP التي ت صن عها لصالح محطة معاجلة مياه صرف صح ي في العاصمة الهنغارية بودابست هي الثانية من حيث احلجم في أوروبا إذ تبلغ قدرتها القصوى النظرية نحو 900,000 متر مكع ب من املياه يوميا وذلك يغط ي نصف مياه الصرف ومياه األمطار الصادرة عن العاصمة. اختيرت أنابيب HOBAS نظرا ملتانتها وخف ة وزنها ومقاومتها للتآكل الكيميائي ومنعها التام للتسر ب. أقيم هذا املشروع برعاية اإلحتاد األوروبي وبطريقة مراعية للبيئة احمليطة وسيبدأ العمل به في العام احلالي وهو يقع على جزيرة Csepel في نهر الدانوب والتي تشك ل جزء من العاصمة بودابست.

45 أخبار صناعية األنابيب وأجهزة كشف التسر ب Pipes & Leak Detectors Dresser Piping Specialties fits Alstom Hydro Venezuelan project with four penstock couplings for two 246 inlet pipelines When Alstom Hydro needed custom-built couplings for a Venezuelan penstock project, they turned to a company they knew could handle custom needs, Dresser Piping Specialties, a division of Dresser, Inc. Penstock segments Customer project challenge The new hydroelectric power plant in Venezuela included a penstock line located near the inlet of a newly installed hydraulic Francis Turbine (275MW). Design engineers needed four Penstock Couplings to fit two 6,205mm (246 ) inlet pipelines. With a design pressure of 170 mwc (meters static water head) (242psi), and a test pressure of 221 mwc (314psi), this large diameter line required sleeve-type pipe joining couplings that would assure a leaktight seal on the inlet lines. To remain tight, the joints must maintain a constant gasket seal under all conditions of pipe movement, including vibration, deflection, expansion and contraction. Furthermore, this particular power plant is located in an area of South America vulnerable to seismic activity. For safety assurance, Alstom engineers specified a coupling product offering flexibility in accordance with external forces. Being a non-rigid union, this beneficial flexing occurs when installing sleeve-type Dresser penstock couplings, which are built to absorb stresses associated with seismic movement. Flexibility of the couplings also helps to eliminate shimming or time-consuming adjustment of anchors, saddles, and girders. Dresser solution Engineers at Alstom had the confidence that Dresser could provide an engineered solution, custom-build their cou- plings within budget and deliver them on time. Dresser engineers prepared design drawings that were submitted and approved for a segmental concept. The coupling design was comprised of three 2-1/4 thick middle ring radius sections to be welded into a complete 360-degree middle ring on site. Gaskets were set, and modular sectional followers were bolted in place. This design significantly reduced shipping and transportation costs and reduced installation labor costs at the job site. Segmental couplings, followers, all bolts, nuts and gaskets were shipped in two sealed containers for transport to the job site. Business benefits When hydropower installation sites involve rocky terrain, substantial savings can be realized in construction costs by having the coupled penstock flow across the surface to avoid excessive excavation and fabricated bends. A standard Dresser coupling in the larger diameter range can absorb up to one degree of deflection. On the basis of 40-foot (12 meters) pipe lengths, this means an offset of up to eight inches per section from the vertical or horizontal alignment is permitted. Should minor settlement occur after penstock construction, the couplings will absorb the resulting deflection without leakage - and without transmitting harmful stresses to the pipe or pipeline supports. قامت شركة Alstom Hydro باإلستعانة بخدمات Dresser Piping Specialties لتأمني لوازم وصل األنابيب وقنوات نقل املياه ملشروع توليد للطاقة الكهرومائية في فنزويال. إحتاج مهندسو تصميم املشروع ألربعة وصالت أنابيب لتركيبها على خطي أنابيب بقطر 6,205 مم تؤم ن حماية كاملة من التسر ب لهذه األنابيب التي تسمح للمياه بالدخول إلى املنشأة. ونظرا لتواجد هذا املشروع في منطقة من أميركا اجلنوبية م عر ضة للزالزل فقد طلب املهندسون في املشروع وصالت أنابيب مرنة بإمكانها مقاومة عوامل ضغط خارجية هذه املرونة تسمح أيضا بإزالة ضرورة تعديل وصيانة العوارض والصم امات وغيرها من مكو نات احملط ة الكهرومائية. تستفيد Dresser لتنفيذ هكذا مشاريع من خبرة 125 عام في هذا املجال.

46 industry spotlights Pipes & Leak Detectors األنابيب وأجهزة كشف التسر ب ADS HDPE pipe receives 100-year service life approval New UNISPEED USFL 90/37 Advanced Drainage Systems, Inc. (ADS), the world s largest manufacturer of HDPE pipe, is the first and only HDPE manufacturer in the underground drainage industry to receive a 100-year service life approval for its revolutionary N-12 corrugated HDPE pipe. The designation, given by the Florida Department of Transportation (FDOT), approves N-12 pipe for use in most FDOT applications. Utilizing the most extensive testing protocol in the pipe industry, FDOT granted approval for 18» (450mm) through 48» (1200mm) ADS N-12 pipe under the «Class II» 100- year service life designation. «The test results in Florida prove there is an increasing level of confidence in the use and performance of HDPE pipe,» said Joe Chlapaty, chairman and chief executive officer of ADS. «Our goal is to deliver a product that will still be in the ground for generations to come and performing its intended purpose. We ve always been confident that our products will last forever, and these tests simply serve as additional evidence to that fact. As with all ADS products, our customers can be assured that our HDPE pipe is providing a high quality, value enhanced solution to meet their underground drainage needs.» ADS s N-12 HDPE pipe is the world standard for corrugated polyethylene drainage pipe. Introduced in 1987, N-12 dual wall pipe, with its smooth interior wall and corrugated exterior wall, offers exceptional hydraulics and strength. Built using application specific highdensity polyethylene, N-12 corrugated pipe also provides superior corrosion and abrasion resistance making it an excellent alternative to reinforced concrete and corrugated metal pipe. According to ADS, the approval in Florida will mean significant growth among the company s public transportation infrastructure projects. «We sell pipe day in and day out in Florida, but this approval will open numerous doors in terms of growth for ADS and our N-12 product line,» said Bob Klein, vice president of sales and customer relations for ADS. «By manufacturing pipe within the state of Florida and keeping our product as close to our customers as possible, it will significantly reduce the time and cost of delivery. The ability to expand the applications of N-12 pipe will advance the industry as we know it today.» To determine the expected service life of the corrugated HDPE drainage pipe, FDOT adopted a test protocol specification that is the most stringent and comprehensive in the pipe industry. Incorporating projected long-term buried stress and environmental conditions, the test protocol utilizes the Rate Process Method (RPM) and Oxidation Induction Time (OIT) testing to measure stress crack resistance and product durability. These methods are well-established and widely used in the pressure pipe industry as a means to predict the long-term performance of thermoplastic pipe. Introduced in 1987, N-12 smooth interior dual wall pipe meets strict quality control from raw materials to production - conforming to ASTM and AASHTO standards - and is specified nationwide in storm and sanitary sewers, agricultural drainage, road and highway construction, residential and commercial development as well as turf and recreational applications. ت قد م شركة S.r.l.

UNISPEED USFL 90/37 from OP S.r.l. is the new machine for 37 and 90 orbital flaring of hydraulic rigid pipe ends with ISO and ISO fitting systems. Practical and easy to use: These are the main features of this machine which requires only one tool change to carry out the flaring operations. This way, processing time is reduced to the minimum since it is carried out easily without the need of additional equipment. The machine uses a cold orbital forming process to create a flat and smooth sealing surface at 90 and 37 with a suitable rugosity for the O-Ring seal. By doing so, it avoids the formation of processing signs which, on the other hand, can occasionally occur with common axial deformation processes. This system is compliant with the pipe flaring requirements regulated by SAE and ISO standards. The various possibilities of adjustment and configuration of USFL9037 allow obtaining any flaring diameter and thickness. The semi-automatic processing cycle allows the flaring process to be very fast, thus reducing costs and avoiding welding or soldering the clamping ring to the pipe end. Moreover, the final cycle lay-up ensures optimal flaring and finishing results. Refer to RIN 42 on page 88 Refer to RIN 43 on page Arab Water World (AWW) April 2009 / Vol. XXXIII Issue 4

Refer to RIN 44 on page 88 The Permalog Patroller drive-by data capture system from Halma Water Management now incorporates the latest Microsoft MapPoint technology and GPS to accurately record the location of each deployed Permalog leak detector. This means that operators no longer need to go through the tedious and time-consuming task of manually marking logger locations. When each new Permalog is deployed, the Patroller uses a wireless handheld scanner to retrieve each logger s unique serial number via Bluetooth technology. This information is then linked to its GPS position with MapPoint software, plotting the network of leak detectors for future reference and analysis on detailed mapping software. A database of Permalog detectors and their precise whereabouts is built up, along with the latest leak monitoring measurements and instant visual cues for any alerts: A green flag indicates that all is well, and a red flag means there s a leak. Having the location mapped then makes it easier than ever to quickly dispatch leak repair teams directly to the trouble spots. Historic data for each unit can also be called up, allowing for a systematic analysis of leak positions over time, and all the data can also be exported in.csv format for water company GIS systems, to be overlaid onto water network plans. This information can then be used to identify problem areas of the water network in the past, present, and potentially future. Another benefit of automatic location logging is the asset security it offers no more units lost due to inaccurate or mislaid maps, and easier retrieval for temporary lift and shift operations.

49 أخبار صناعية املعد ات املخبري ة وأجهزة القياس Laboratory Equipment & Instruments The new WATERFLUX 3070 battery-powered water counter eddy currents are minimized and allow for highly accurate measurement (± 0.2% ± 1.5 mm/s). The tube itself is highpressure stable; it is made of cast aluminum with a coating of Rilsan, which is approved for potable water. For the operation of an electromagnetic water meter, electrical energy is needed. However, in many cases, the remote location of the meter makes connection to the electricity grid impossible. KROHNE have overcome this issue, by giving the WATERFLUX 3070 a battery life of up to 15 years until the battery has to be changed. This means it is maintenancefree and can be operated at very low maintenance costs. Its long lifetime is due to its unique sensor design, and the very low power consumption of the components within the counter. Due to this modern technology, the power consumption is lower by a factor of 5,000 compared to a conventional electromagnetic flow meter. KROHNE introduced a new measuring instrument: The WA- TERFLUX 3070 is an electromagnetic water counter for standard applications in the water and wastewater industry. It has a very long battery life of 15 years, making it especially suitable for applications where no power connection is available. The counter also has the option of a GSM module for remote transmission of measurement data and status information. The WATERFLUX was showcased in March 2009 at both the Aqua Nederland and Wasser Berlin exhibitions. The new WATERFLUX 3070 offers the user some unique benefits that comparable solutions lack: Thanks to extremely short inlets and outlets, the WATERFLUX can be installed in very narrow wells and chambers. The counter is highly accurate and being a magnetic-inductive meter, it is superior to mechanical water meters in terms of pressure loss and longterm stability. For large diameters, the WATERFLUX 3070 has a significant price advantage compared to the lifetime cost of mechanical meters which require filters and rectifiers as well as maintenance and cleaning. The heart of the WATERFLUX is the measuring tube with a rectangular cross section, which offers several advantages: The coils are arranged so that a strong, homogeneous magnetic field is formed and the measurement is thus independent of flow profile. In addition, this allows for extremely short inlets and outlets. The optimized thickness of the metering If no power supply system is available, often the connection to the PLC is also not available. Therefore, the user at water sources, wells, or network transfer is reliant on remote data transmission. For the WATERFLUX 3070, a Datalogger and GSM transmitter as a compact module are available. The Data Logger stores all data, including peak flow and low flow during the night. This information is then transmitted by the GSM network to the next radio mast and from there via satellite to a server that the user can access. As well as providing accurate flow measurement, the WA- TERFLUX 3070 can also indicate the charge conditions of the battery as well as the draining of the tube. The WATERFLUX 3070 meets the requirements for custody transfer according to OIML R-49 and MI-001. The device is available in sizes from DN 25 to DN 600. WATERFLUX is also available in combination with the well known signal converters IFC 100 and IFC 300, enabling the application and benefits of the unique sensor design in those industries where there is mains power at hand. The new WATERFLUX 3070 will be still available for viewing at Wasser Berlin until April 4. KROHNE was established in 1921, KROHNE is a familyowned business employing 2,510 people around the world with representatives on all continents. The company headquarters are based in Duisburg, Germany.

52 country / regional reports Iraq العراق New strategies and monitoring for the requirements of water projects in Iraq The water and electricity sectors represent the largest challenge for the current Iraqi government. The Iraqi governmental program and international reconstruction program from MND contribute in supporting and developing these sectors after many years of neglect. In fact, it was impossible to rehabilitate the old projects because they had reached their expiry date. For this reason, the reconstruction programs aim to construct new water projects with different capacities, where some of these projects are designed to only treat the raw water then pump it to the water pipes network, while the other projects are designed for the production of desalted water by using reverse osmosis desalination technology. Unfortunately, reverse osmosis projects are still unable to cover the total water requirements for drinking and industrial sites. Up until now, water desalination projects depended on selling the produced water to water contractors who are responsible for transporting and selling it to customers. Existing water station at Garmat Ali By Dr. Ala a Abdulrazaq* water directly to Basrah s central water station. Also, the low lift pump station is provided with four water pumps (4*1,500 m 3 / hour), the station is responsible for pumping the raw water to two water compact units (2*400 m 3 /hour) where the raw water will be treated by using alum and disinfected by gas chlorination systems. Recently, the development of the Iraqi water sector gained momentum as many new water projects are under construction and the rest are already operating. Interestingly, most of the new water projects were executed or under construction by Iraqi contractors. The contractors are responsible for preparing the full details: Civilian, electrical, mechanical, and chemical drawings and cost estimation for all items in the scope of work. The contractors office for supervision will evaluate these items before giving the official acceptance and certification for starting with works in these new sites. After that, the contractors will be responsible for site mobilization and recruiting specialized engineers and employees. The contractors must also submit official documents before delivering any new equipment or materials to the site. The contractors office will evaluate the specification before giving the approval in case it is identical to the scope of work requirements. For most new projects, the safety factor must be achieved and available in all work stages. The safety engineers must continue monitoring all safety aspects inside the projects. Also, safety engineers from the contractors office will check the safety issue. Sometimes, projects can be turned off when safety requirements are not met. Many safety reports must be prepared during the project s development stages, and multi safety meetings must be carried out on site and at the contractors office. Many examples are available in the city of Basrah where many water projects are under construction. For example, Garmat Ali water project is considered one of the main projects in the city. The project s budget from USACE-GRS corps of engineer is about US$ 8 million. This project aims at constructing a new water treatment station beside the old one.

Three chlorination injection points and three mixers are connected on the roof of the water storage tank. The storage tank is connected with the high lift pump station which is made of five water pumps (5*1,000 m 3 ) and responsible for pumping the treated water to the villages around the water station. The site is provided with three gas chlorinator systems (10 kg/hr) from a hydro-instrument company along with four diesel generators (4*1Mw). The new water project has a very large laboratory and will be provided with several equipment for testing and measuring. Many items are still under construction such as restrooms, parkings, overhead cranes, compressors, transformers, chlorination building, electrical building, sunshields, route roads, steel intake water structures, diesel generator building with transformers, 33 KV cable equipment, and lightning protection system. The regular work systems and the new strategies in the water sector in Iraq encourage many international companies to make many investments in this sector as prime contractors or subcontractors, especially if the security situation becomes more and more stable in the country. *Assist.

53 العراق Iraq تقارير البلدان واملناطق USAID promotes water management for farmers Bathing in the Euphrates US aid officials and members of the Iraqi government recently attended a symposium designed to improve the rural sector s productivity through effective water management and proper crop selection, as reported by The Tech Herald. The March 4, 2009 irrigation conference titled Reviving Irrigation Districts was inaugurated by the U.S. Agency for International Development (USAID) Deputy Mission Director Thomas R. Delaney and the Iraqi Minister of Water Resources Dr. Abdul Latif Jamal Rashid in the capital Baghdad. The program looks to encourage higher value and more water efficient crops, examine participative water schemes and also examine the possibility of bringing in the expertise and higher funding of public-private partnerships. The agency says that such partnerships would promote the use of efficient irrigation and relieve governments of the حضر مؤخ را مسؤولون من احلكومة العراقية ومن منظمة USAID األميركي ة للتنمية الدولية ندوة م خص صة لتحسني إنتاجية القطاع الريفي وذلك من خالل إدارة املياه الفع الة وحسن إختيار املزروعات. تأتي هذه الندوة كخطوة إضافية لدعم هذا القطاع من قبل USAID حيث استثمرت املنظمة حتى اآلن في العراق 6 مليار دوالر أميركي منذ العام Refer to RIN 54 on page 88 responsibility of maintaining irrigation infrastructure. The water management program complements USAID s other work in Iraq where it has responded to the country s needs by investing US$ 6 billion since 2003 on projects designed to improve national, local, and provincial governance and communities. Agriculture is the largest single employer in Iraq and its second most important industry behind oil. The country has close to 12 million hectares of land deemed suitable for farming as the area is surrounded by the Tigris and Euphrates rivers. According to USAID, of the 12 million hectares, 8 million are considered irrigable with the remainder relying on rainfall. However, serious neglect of irrigation infrastructure over a period of twenty years by Iraqi farmers has led to...serious deficiencies and degradation, constraining availability of water for agriculture, said the aid agency statement. In order that these challenges be met head on, USAID s Inma Agribusiness Program invited leading Iraqi agricultural researchers, economists, and policy experts to review and identify advances needed to manage farm production with limited water resources. Refer to RIN 55 on page 88 Utilizing fresh skills and resources, the program aims to analyze a range of options for Iraqi farmers to manage water efficiently and obtain higher crop yields. عالم املياه العربي 51 نيسان )أبريل( / 2009 مجلد - 33 عدد 4

55 تقارير البلدان واملناطق تركيا Turkey Water sector privatization and management in Turkey Water shortages in Turkey, in recent years, have become a widespread problem that has been exacerbated by rapid urbanization. Of the total surface runoff of the country, estimated at cubic kilometers per year (km 3 /year), almost one-fourth comes from the Euphrates and the Tigris rivers, which both have their sources in the eastern part of the country. Turkey contributes about 90% of the total annual flow of the Euphrates, while the remaining part originates in Syria and nothing is added further downstream in Iraq. Turkey contributes 38% directly to the main Tigris River and another 11% to its tributaries, which join the main stream of the Tigris further downstream in Iraq. In general, the streams vary greatly in their flow from season to season and year to year. For example, the Euphrates annual flow at the border with Syria ranged from 15.3 km 3 in 1961 to 42.7 km 3 in Privatization Turkey was one of the pioneers in the use of BOT contracts (build-operatetransfer) in the developing economies during the early 1980s. There is a high level of public support for privatization, but political opposition and legal problems remain. Turkish courts are responsible for the operation of BOT concessions whereby the courts have to clear each project and all objections to them. This makes life difficult for international finance, whereby some form of independent international arbitration would be more attractive. It is widely expected that water privatizations will take place in the medium term. In this sense, Izmit (bulk water provision) and Antalya (O&M, water and sewerage) are groundbreaking contracts. Urban Services Safe Drinking Water 91% Access to sewerag 84% % sewage treated 5% International players noted SUEZ and Thames Water have a major presence in the country, while United Utilities/Bechtel and SAUR were involved in the bidding for Antalya. Spending plans The Istanbul Water and Sewerage Administration (ISKI) allocated US$ 450 million for infrastructure projects in 2003, with an emphasis on sewerage and sewage treatment. Water fountain in front of the Blue Mosque, Istanbul Izmit Izmit had a troubled start because of the Turkish BOT award system delaying the start of the contract implementation process for nearly two years. Since then, the three year construction phase has been completed, and in 1999 the contract entered its 15 year operational phase. A reservoir supplies water to Izmit, the surrounding towns and villages and to Istanbul. The project involved 100 kilometers of pipeline being built, connecting the reservoir to the city of Izmit. The reservoir has a capacity of 60 billion liters with an annual yield of 142 billion liters. The water treatment works is 5 kilometers downstream from the reservoir, and has a capacity of 480 million liters/day. The treatment facilities cost US$ 100 million to build. The project was 85% debt and 15% equity financed. US$ 140 million of equity finance was provided by Thames Water (UK, 35%), Mitsui (Japan, 7.5%), Sumitomo (Japan, 7.5%), Gama (Turkey, 23%), Guris (Turkey, 12%), and the remaining 15% by the Izmit municipality. These investments are reflected in their respective holdings in Izmit Su As, the operating company. US$ 803 million of debt finance was arranged, the principal components were: US$ 236 million Export Credit Guarantee Department (ECGD) supported credit loan arranged by Nat West (UK), US$ 167 million Turkish commercial loan, US$ 180 million COFACE buyer credit loan, US$ 40 million Japanese commercial loan, and US$ 180 million JEXIM credit loan. Adana A short term wastewater treatment BOT Adana had a population of 1.22 million in The city had no wastewater treatment facilities until a BOT contract was signed in 2001 with a consortium headed by VA Tech Wabag (Austria) funded through a US$ 58 million EIB loan. The two treatment plants entered service in 2004 and were operated by VA Tech until They can treat 0.2 million m 3 /day, a capacity which will be increased to 0.4 million m 3 /day by 2015, and 0.52 million m 3 /day by 2025, serving up to 2.6 million people. In 2001, the city awarded MVV (Germany) a 2 year water leakage management contract, which has now been concluded.

57 تقارير البلدان واملناطق تركيا Turkey Leaders on trial at water tribunal in Istanbul Turkish and foreign leaders were placed in the dock in a mock trial in Istanbul on March 10, 2009 on charges of endangering the environment at a symbolic tribunal composed of environmental activists according to AFP. Turkish actress Pelin Batu attends the mock trial The initiative, aimed to raise awareness on water resources management, preceded the fifth World Water Forum, which began in Istanbul on March 16 with the participation of government officials, business people and civic groups from about 180 countries. The jury of a mock trial is seen in Istanbul The idea is to bring to public attention problems related to the water policies of the governments in Turkey, Brazil, Mexico, but also internationally, said Ulrike Dufner from the German foundation Heinrich Boll Stiftung, which cosponsors the symbolic tribunal. The initiative aims to underline that access to water is a human right and that we are violating a human right when we privatize water resources, she told AFP. The tribunal targets Turkish Prime Minister Recep Tayyip Erdogan over the Yusufeli dam project, which, according to the activists, would meet 0.6 percent of Turkey s power needs, while forcing the displacement of 16,000 people in the northeast and damaging local biodiversity. Also facing charges is Chancellor Angela Merkel over German plans to help finance the construction of the Ilisu Dam on the Tigris River in southeast Turkey, which would displace 54,000 people and submerge a prominent historical site. The activists also target dam projects on the Madeira River in Brazil and accuse Mexico over a worsening environmental situation in the country. جرت محاكمة صوري ة في 10 آذار )مارس( 2009 في اسطنبول للقادة السياسيني األتراك واألجانب بتهمة تعريض البيئة وموارد املياه للخطر. هدفت احملاكمة إلى توعية الرأي العام مبا يخص إدارة موارد املياه وذلك قبيل افتتاح املنتدى العاملي اخلامس للمياه في اسطنبول الشهر املاضي حيث شارك فيه مسؤولون حكوميون ورجال أعمال ومجموعات من املجتمع املدني من 180 بلدا.

58 country / regional reports Scandinavia الدول االسكندينافية Jungle Book As if building a 217 MW power plant in a tropical jungle wasn t hard enough, workers on the Changuinola Hydroelectric Project also have to cope with a kaleidoscope of wild animals. Brian O Sullivan reports from the depths of northern Panama. 70-ton EC700, a G710B motor grader, and a BL60 backhoe loader. The fleet of machines has had their work out since arriving in May 2007, as creating the haul roads alone has been an epic undertaking. With a completion date set for 2011, machine reliability is of paramount importance, and the entire Volvo fleet is protected by a Gold customer support agreement. This takes over responsibility for the repair and servicing and Volvo guarantees the fleet s mechanical availability will not dip below 90% between the machine hours of zero to 8,000 hours. In actual fact, total fleet availability after the first year of operation was an incredible 98.31%. We all complain about the inconveniences of our jobs from time to time. And in construction those inconveniences can be worse than most. Long hours, exposure to the weather, deadline pressure, months away from families there is plenty of things to grumble about. But the next time you feel a complaint coming on, remember the workers on the Changuinola Hydroelectric Project in the depths of the Panamanian rainforest. They have to cope with all of the above as well as scorpions creeping into lodgings, poisonous snakes dropping onto them from trees, black panthers, pumas even killer bees! But this expansion is putting pressure on the country s infrastructure, not least its power generation capability. To overcome this, an ambitious plan is being put in place to harness the power of the country s rivers to provide a sustainable electricity supply. The Changuinola Hydroelectric Project Panama is the flagship scheme. A 90-meter high roller compacted concrete, 545-meter wide dam will hold back a reservoir of 122 million cubic meters, and channel water down a 3,952-meter long concrete lined headrace tunnel to a main 207 MW turbine. The project, when completed, will deliver 939 GWh of power a year. Close to the border with Costa Rica and 600 kilometers from the capital Panama City lies Changuinola, a fishing village named after the River Changuinola besides which it is built. Home for centuries to Indian tribes, the only previous outsiders to have ventured to this dense rainforest were banana farmers and adventurous tourists seeking the ultimate get away from it all holiday. But now Panama is changing. The substantial expansion of the country s eponymous canal is just one part of a building boom that is increasingly putting the Central American country onto the map, turning it into an important economic and tourism destination. AES Changuinola, a subsidiary of USbased AES Corporation, owns the project, with a consortium comprising French headquartered Alstom and two Danish companies E Pihl & Søn, and MT Højgaard. About 1,000 people have been at work on the project since it began in 2007, and 300 operators are allocated to 150 pieces of mobile equipment. Volvo is the main equipment provider on the project, supplying through its local dealer, Commercial de Motores SA., over 34 machines. The Volvo fleet consists of 16 A35D articulated haulers, 11 wheel loaders, two Rototilt-fitted EW180C wheeled excavators (for embankment grading), one In charge of the Volvo fleet is 41-yearold Tommy Hokkanen, a friendly bear of a man who grew up in the Swedish town of Vaxjo, where Volvo s haulers are made. With the help of local supervisor Abraham Acosta, nine technicians and five containers full of parts and tools, Tommy and his team work 18 hours a day in two shifts, six days a week. It s hot, wet and sticky here, with plenty of wild animals and bugs to watch out for, smiles Tommy. But these are not just difficult conditions for humans - it s tough for the machines too.

Sometimes it makes it stick even worse and it becomes a big sticky cake of mud! But these machines are doing well, the ec700 is good at clearing, stripping overburden and mass excavation, while the wheel loaders are feeding crushers and supplying rocks from the river. getting good people to work in such extreme conditions is difficult, and Tommy and Abraham go to great lengths to train the operators. this will include training on the use of a side tipping bucket when the wheel loaders start to work inside the headrace tunnel. no excuses on safety Being a vast scheme covering such a wide area, local Indian tribes are literally living inside the construction area. this means that adults and children walk along the haul roads and have to be borne in mind with every activity. Site safety is taken extremely seriously, with radar controlled speed cameras monitoring speed on haul roads. the penalties for breaking the rules are severe, and include losing the ability to drive on site or being banned from the project altogether. this attitude is working, because apart from the odd snakebite, the site has been remarkably accident free. It s not just safety that is important, states Per Moberg, who is in overall charge of all machine types on the site.

60 country / regional reports Scandinavia الدول االسكندينافية Denmark: HDD boring where an environmentally friendly solution was needed The Søren Knudsen A/S company performed an HDD boring in an environmentally sensitive area. The electrical supply cable to the little island of Hindø in the Stadil inlet was out of order and a new cable was required. Hindø and the low water area around Hindø and Svellebusk have been declared as environmentally protected areas by the Danish government, which means open trenching is no longer permitted. So the contractor, Søren Knudsen A/S, was asked to do a HDD boring between the main land and the island. The boring would be 300 meters under water plus some extra meters on each side of the water body. Approximately 20 meters on the main land for going under some dikes, and also approximately 20 meters on the island for boring beneath a meadow. The Knudsen truck and bore rig ready to start the directional bore GRUNDODRILL from TRACTO-TECH- NIK. The GRUNDODRILLL 8S used for this job was produced in 2003 having more than 5,500 hours accumulated since then. Søren Knudsen A/S was the first company outside Germany to invest in GRUNDODRILL bore rigs in Northern Europe. They got their first machine in a GRUNDODRILL with 6.5 tons of thrust and pull-back. They were also the first to get a GRUNDOHIT 40 in 1996 (a unique machine in the industry, being designed for surface launch and pit launch applications). Years later, Søren Knudsen switched to a more modern and efficient GRUNDODRILL 8S version. On the project described Søren Kundsen A/S used a DCI Eclipse detection equipment from a boat in the inlet and the maximum depth was 8 meters. The drilling fluid was bentonite from MI with a mix of 25 kg Max bore and 0.25 kg PAC pr. m 3. The job was carried out to everybody s satisfaction and a big credit goes to Bent and Lasse from Søren Knudsen for a job well done. TRACTO-TECHNIK is a modern and innovative family-owned company for special machines with its headquarters in Lennestadt, Germany. TT is a specialist for underground installation and pipe bending technologies and experiences an upward trend in trade due to extraordinary, highly beneficial products combined with an excellent service. TT became known as a trademark representing the complete range of pipe installation technologies. Striving direct on target is the company motto. This requires a great deal of flexibility as well as active growth- and benefit-oriented diversity when generating new products and services and developing new markets and target groups. The boring was done in one working day, starting early morning and finish at 7:30 pm - including 3 magazine changes each way. The biggest challenge was to get the 110 PE pipe to the target pit because of the very soft soil on the island of Hindø.

61 تقارير البلدان واملناطق الدول االسكندينافية Scandinavia Denmark a role model to local water market As one of the leading countries in energy efficiency and as a market leader in energy-saving equipment, Denmark could be a role model for the Turkish market according to Jesper Vahr, the Danish ambassador to Turkey. 103 Danish companies are active in Turkey in regards to environment-related issues. The Danish pavilion featured at the expo center of the 5th world water forum in Istanbul, had much to offer Turkey through its consultancy, investments and initiatives and expertise in the water technology industry, said Vahr in an interview with Hürriyet Daily News & Economic Review. Danish energy consumption relative to the country s GDP is the lowest in the European Union. The Danish ambassador expressed his excitement about the forum, saying water was an important part of the equation for energy efficiency and environment-related issues, all coming together in Istanbul at the biggest international gathering for water-related issues. The key is to build the awareness of consumers about environmental responsibility in order to bring down consumption and develop technology and facilities that can sustain less water consumption, said Vahr, adding that in Denmark the total use of water has decreased by nearly 40 percent in the last decade. When asked about Turkey s progress on environmental issues, Vahr said it was evident that these issues receive strong political attention in Turkey and this was confirmed during President Abdullah Gül s visit to Denmark in August The sticking point according to Vahr is that it is a huge investment for Turkey to be brought to EU standards and then to sustain those standards. Vahr pointed out that Turkey signing the Kyoto protocol was of utmost importance where much can be obtained. بإمكان الدمنارك أن تكون مثاال لتركيا في مجال توفير الطاقة وموارد املياه بحسب تصريح لسفير الدمنارك في تركيا السيد.Jesper Vahr تعمل حاليا 103 شركات دمناركية في تركيا في القطاع البيئي وكانت الدمنارك حاضرة بشكل كثيف في املنتدى العاملي للمياه الذي أقيم في إسطنبول الشهر املاضي.

According to Vahr, new drinking water equipment has been put into place and water pipes have been implemented in order to circulate seawater and wastewater safely without seepage. Vahr said that only 20% of wastewater was treated and recirculated in Turkey, whereas in Denmark the majority of water is redistributed through the system. Commenting on the types of water projects Denmark is contributing to in Turkey, the ambassador said that in the main cities of Ankara, Istanbul, and Izmir the focus of the projects were based on water transportation.

Water treatment equipment manufacturers seeking new ways to cut costs and increase throughput of test-intensive assembly operations can now obtain a technical guide discussing Test-Centric Assembly from InterTech Development Company, whose Testing Applications Lab is credited with both coining the term test-centric assembly and pioneering many of the methods and techniques outlined in the white paper. Test-Centric Assembly is best defined as the upfront consideration of real-world test requirements in test-intensive assembly operations that is proven to lower production line inefficiencies. The contents of the technical guide include: Discussion of in-line vs. in-process testing; differentiating between defective parts vs. defective tests; differences in fixture design for testing vs. assembly; comparing generic vs. customized software for testing applications; and related costsavings of various assembly and test techniques. Jacques Hoffmann, President of InterTech Development Company, comments, There are common mistakes made by machine builders or manufacturers that do not understand the details of test processes and what is required to fine tune testing in the context of an assembly operation. Gauge R&R of test instruments does not equate or even correlate precisely with the Gauge R&R of the entire test and assembly operation, for example. InterTech s Applications Lab routinely designs turnkey test and assembly systems that cut test cycle times by as much as 70%. This white paper discusses some of the principles involved in re-engineering for more efficient assembly and test operations without compromising testing integrity. InterTech Development Company is a world leader in testcentric assembly and test specializing in automated leak and functional testing with 7 patented mass flow and hydraulic technologies, as well as, helium mass spectrometry (ISO International Standards for Quality Management). InterTech Development Company-engineered solutions are used by hundreds of manufacturers worldwide.

InStep has three core product suites edna, PRiSM, and EEM. We continue to develop these platforms to ensure that our customers are achieving continued value from their investments in these products. edna (Enterprise Distributed Network Architecture) edna is a software suite of products that provides for collecting, archiving, displaying and reporting a company s real-time operational and asset health related information. The product suite includes a highly scalable enterprise data historian for efficiently archiving and providing rapid retrieval of very high fidelity time series data. A highly advanced lossless compression technology is used to minimize the required storage capacity while maintaining the original collected resolution of the data. InStep supports the ability to easily integrate with hundreds of control, monitoring and other enterprise business systems that companies rely on for day to day operations. An RDBMS database is incorporated into the software suite and layered on top of the time series database to provide for organization and access of the data through the use of an object or meta data model. InStep s advanced edna Client and edna Web technologies can then be used for the real-time distribution of this information to all users throughout the company enterprise. PRiSM PRiSM (PRocess Information Signal Monitor) is a self-learning analytic software application for monitoring the real-time health of critical assets in support of Condition Based Maintenance (CBM). PRiSM uses artificial intelligence, pattern recognition, and sophisticated data mining techniques to determine when a piece of equipment is performing poorly or is likely to fail. The early identification of equipment problems leads to reduced maintenance costs and increased availability, reliability, production quality, and capacity. PRiSM learns from an asset s individual operating history and develops a series of normal operational profiles for each specific piece of equipment. PRiSM then compares the known operational profiles with real-time operating data to detect the subtle changes in system behavior that are often the early warning signs of pending equipment failure.

70 departments Corporate Happenings أخبار الشركات KEMA launches study of large-scale energy storage in European context KEMA has been commissioned by the Dutch utilities DELTA, Eneco, Essent, Nuon, and the General Energy Council to launch a study into the need and necessity of large-scale energy storage. The share generated by renewable energy sources in Europe is expected to increase substantially over the next ten to twenty years in response to the EU s sustainability and CO 2 emission reduction goals. However, the supply intermittency and concentration that characterizes wind generation in particular can at times lead to a regional supply surplus. A solution must be found for dealing with these supply peaks and fluctuations. Large-scale energy storage may be the answer. The need for greater clarity on this issue has also been expressed in the Dutch parliament on several occasions over the past year. The study will be conducted from a European perspective, and is due for completion in June of this year. Masdar, founder of the highly successful World Future Energy Summit (WFES), joined with Turret Middle East, the 2009 WFES conference organizer to announce the launch of the European Future Energy Forum to take place in Bilbao, Spain from June 9 to 11.

However, it is questionable whether increased electricity export or import can adequately compensate for simultaneous oversupply from wind farms across the entire continent. Large-scale energy storage may be the solution for dealing with such surpluses more efficiently, so that wind energy can be utilized to the full. Moreover, largescale energy storage provides options to tackle instability in the grid, and it can play a role in generation load-balancing and solving network control issues. In this study, KEMA will execute a realistic simulation, based on its own European market model that covers much of the European electricity grid. The model incorporates various scenarios related to developments in wind energy and fossil fuel prices, as well as future developments in power generation and network interconnection. The support of government leaders and energy experts at WFES 2009, which was attended by more than 18,000 visitors from 70 countries, was another critical element in encouraging us to take our experience to the international arena. Given the current economic situation, we believe this is the time to be competitive, creative and innovative. Our goal is to drive the development of clean energy sources that are instrumental in advancing renewable energy. By bringing the European Future Energy Forum to Europe, we are looking to create opportunities and partnerships in renewable energy that will be a stimulus for economic growth for the region, and beyond, added Al Jaber. Furthermore, through these open platforms for collaboration Abu Dhabi aims to continue its leadership in the energy sector, and share its knowledge with others, added Al Jaber. 68 Arab Water World (AWW) April 2009 / Vol. XXXIII Issue 4

72 departments TrojanUV rated China s top disinfection equipment again Products & Services منتجات وخدمات Nelson Irrigation Corporation announces the release of the new R33 Rotator After years of planning, design, testing, and development, Nelson is pleased to announce the release of the R33 Rotator. Nozzle sizes 9/64, 5/32, 11/64 and 3/16 are now available. Trojan Technologies has once again been rated number one in the category of Outstanding Water Disinfection Equipment Brand in the annual independent Outstanding Equipment Survey conducted by China Water Net, the most influential online resource for China s water industry. Based on a sample of more than 220 water treatment equipment customers, manufacturers or brands were listed in order of number of votes received and evaluated in the categories of: 1) most recognized brand that a customer knows; 2) most used brand by a customer; 3) customer satisfaction on the quality of the equipment; 4) customer satisfaction on after sales service; and, 5) good value for price. Of the 21 measuring indexes for the survey, Trojan scored in the top three spots for each category. Receiving this recognition for the second year in a row is a reflection of our talented and focused group in China. The Trojan team has worked diligently to bring reliable and costeffective UV-based disinfection solutions to our global community, says Marvin DeVries, Trojan president. We are honored to have received this prestigious recognition. Trojan Technologies is a wholly-owned subsidiary of Danaher Corporation of Washington, D.C. Trojan designs, manufactures, and sells UV systems for municipal wastewater and drinking water facilities, as well as for the residential market. The company also designs and installs treatment technology for the environmental contaminant and micropollutant destruction market and partners with Aquafine Corporation of Valencia, California to provide UV solutions to the Industrial and Commercial markets. With over 5,600 municipal facilities in more than 80 countries using its technology, Trojan has the largest installed base of UV systems in the world. Headquartered in London, Ontario, Canada, the company also has offices in the U.K., China, Germany, the Netherlands, France, Spain, and the U.S. The R33 Rotator is an innovation that saves money, saves time, and performs better than the 3/4 brass impact sprinklers it s designed to replace. Created as an upgrade to replace the Nelson F33 brass sprinkler, the R33 uses Nelson s proven Rotator Technology to provide longer throw distance, fight the wind and deliver uniform coverage. With new advancements in speed control, its break-through design allows the sprinkler to move from slow mode back to a fast mode throughout its rotation. By reducing the speed of rotation intermittently, the R33 produces a wind-fighting pattern with maximum throw distance. The fast mode also assists in filling out the water pattern for greater uniformity. While brass sprinklers are prone to damage, clogging and theft, the R33 is easy to clean, easy to repair, and costs less. The R33 is suitable for permanent-set, portable-pipe and wheel-line applications for all type of crops, including forage crops, vegetables, grain, and pastures, as well as tree and vine crops.

73 مشاريع وتطويرات Projects & Developments أقسام BAHRAIN Manama opts for low-risk sell-off Bahrain is taking no chances with its wastewater privatization. With water-loss levels unacceptably high and the quality of treated water so poor that the agricultural sector refuses to use it for irrigation, it is clear the state-run utilities should be replaced. The entry of the private sector will bring much-needed investment, technology, and experience to improve standards. There will be no shortage of interest from international developers. Because the Muharraq sewage treatment plant is the first part of the privatization plan, the government has opted for a low-risk approach by guaranteeing the supply of effluent and the offtake of treated water. This relieves the developer of much of the risk and ensures a steady stream of income, but it is not necessarily the most efficient system for the state in the long run. In time, Manama will hope to invite companies to take control of the wastewater collection and distribution networks, thereby passing on market risk to the private sector. The hope will also be that as efficiencies and services improve, domestic and industrial users will be more willing to pay more for their wastewater treatment. Water privatization in the region is gaining traction, with Saudi Arabia and Abu Dhabi already bringing in the private sector. If they can make the schemes work, more of the region will surely follow and perhaps take more risks earlier on. QATAR QIB closes US$ 250 million financing arrangement for Ras Lafan Power & Water project Qatar Islamic Bank (QIB) announced that it has successfully closed an arrangement for an Islamic Financing for a part of the Ras Lafan Power & Water project (C) that would be performed by Ras Qirtas Power Company at a cost of US$ 250 million. The project, a six multi-effect distillation desalination units, shall be executed on BOOT basis (Built-Own-Operate-Transfer). With a total cost of over US$ 3 billion, the project, expected to be completed by 2011, aims at enhancing the power production rates and ensure the provision of water and power to face the country s increasing demand on power. In addition to approximately 6.3 MIGD [Million Imperial Gallon (of water) per Day], the project will generate around 2,730 Mega Watt of electricity, thus covering 30% approx. of the country needs. It is worth noting that Qatar Islamic Bank and Islamic Development Bank will be the mandated Lead Arranger and Underwriter, whereas its Main sponsor/ shareholder will be: Qatar Petroleum, QEWC, Suez Energy International, Mitsui. In a comment made on this occasion, Mr. Salah Al Jaidah, Chief Executive Officer of Qatar Islamic Bank, said: The success of QIB in closing the arrangement of this financing confirms our capacity to takes the responsibility of providing the adequate Islamic financing for the vital development projects in Qatar. He added, Further, in its five-year plan that started in 2008, QIB will endeavor to consolidate its role in financing the State s macro-projects and enter with its partners, whether its QIB-offshore financing houses or Islamic Financial institutions worldwide, in joint ventures to attract such investments to Qatar, guided by our duty as a national economy-oriented bank. From its part, the GM of the bank s Investment & Development Group, Jean- Mark Riegel stated: The success of QIB in arranging this financing in cooperation with the Islamic Development Bank has gained confidence of large national establishments. He added, This success is a continuation of previous successful financing arrangements for huge establishments like the Qatari Water & Electricity company, Qatar Airways, the United Development Co., Al Salam Bounian Co. and others. UAE Complete overhaul for Abu Dhabi sewer network The Abu Dhabi Sewerage Services Company (ADSSC) is inviting selected contractors to prequalify for the US$ 545 million deep-tunnel sewer as part of its plans to overhaul the sewerage network in the emirate. The tunnel will run for 42 kilometers from the existing pumping station on Abu Dhabi island to the Mafraq wastewater plant, before heading towards the Al-Wathba wastewater treatment plant. The tunnel is being tendered as three design-and-build contracts. One will be for a four-meter diameter 16.2km-long tunnel from Abu Dhabi island onto the mainland. Another will be for a 15.6km tunnel with a diameter of 5 meters from the Musafah area to Mafraq. The third involves the construction of a 10km tunnel with a diameter of 5.5 meters, between Mafraq and Al-Wathba. Each contract requires the design and construction of the main tunnel, access shafts and short connecting tunnels. It also covers any additional work such as data acquisition, liaising with other agencies, seeking statutory approvals and relocating services and equipment. The tunnel is a major component of Abu Dhabi s US$ 1.08 billion Strategic Tunnel Enhancement Programme (Step), formerly the Strategic Investment Programme. The project also includes developing one or two pumping stations along deep-tunnel sewer routes, a series of smaller sewers connecting existing sewerage systems to the deep-tunnel sewer, and the removal of existing pumping stations. The gravity tunnel and the sewers feeding into it will enable ADSSC to eventually decommission several existing pumping stations, thereby reducing its operating and maintenance costs. US-based CH2M Hill is the program manager for Step and the entire program is expected to take six years to complete. Sewerage is a growing concern in the capital as the development of major real estate projects will dramatically increase the population on Abu Dhabi island and the surrounding areas. The Urban Planning Council expects the population to exceed 3 million by 2030, as residents move into island projects such as Reem, Saadiyat, Yas, and other developments on Abu Dhabi island itself. Several other sewerage schemes are underway in the emirate. Two consortiums have been awarded 25-year concessions to build, own, operate, and transfer sewage treatment plants at Al-Wathba, serving Abu Dhabi, and at Al-Saad, serving Al-Ain. One contract was awarded to a consortium of the UK s Biwater Group, Kuwait s Mohamed Abdulmohsin Kharafi & Sons, and the local Al-Qudra Holding. The other was awarded to the French/Belgian joint venture of Veolia and Besix. Both groups will build two plants, one at each location. The plants for Abu Dhabi will have a capacity of 300,000 cubic meters a day, and the plants for Al-Ain will be able to treat 65,000 cubic meters a day. 71 عالم املياه العربي نيسان )أبريل( / 2009 مجلد - 33 عدد 4

76 events Event Review معارض ومؤمترات سابقة Sharing of visions makes second Aquaterra a resounding success and Rhine into the heart of their respective nation s economy and agriculture. He adds that the delegates concluded: Unbridled coastal urbanization, reclamation, and port development threaten natural dynamics and are leading to major problems such as floods, erosion, polluted estuaries and a scarcity of fresh water supply for drinking water and agriculture. While various smart new solutions were presented at Aquaterra, the conference attendees noted the scarce attention being paid worldwide by governments to deltas. This is resulting in inefficient spatial planning and, consequently, an unnecessary loss of nature, drought, fresh water problems, and increasing flood risks. Rodenhuis: The conference participants agreed that politicians need to be made far more aware of the issue of delta vulnerability than is currently the case and stressed the necessity for greater governmental involvement. Mrs. Nighof - Director General of the Dutch Ministry of Transport Aquaterra 2009 was the second edition of the world forum on the development of delta and coastal areas and took place from February 10 to 12 in Amsterdam RAI. The three-day Aquaterra 2009 attracted over 600 top experts from around the world. They discussed in depth how best to ensure a sustainable future for the world s largest deltas, many of which are the economic powerhouses and food baskets of nations. The Aquaterra conference delegates issued a joint closing statement that became a key topic of discussion at the fifth World Water Forum in Istanbul in March. Major river deltas and estuaries face ever greater challenges from urbanization, infrastructure and agriculture development, with over 80% of the world s population expected to be living and working in these regions in the near future. The sea level rises and storm water problems associated with global warming will aggravate matters further, and were a clear source of concern among experts at Aquaterra Countering risks and reducing damages With the likely effects of climate change still to come and the foreseen growth of coastal cities, the strain on the dynamic natural system will sharply increase. Solutions are available within the parameters of the natural system itself. Examples include restoring some of the natural sedimentation of the Mississippi river, preserving mangrove forests along the coast of Bangladesh, and reclaiming land along the Dutch coast by semi-natural beach nourishment. New civil engineering solutions were also discussed at Aquaterra, such as Tokyo s super levees and the dredging of the inner city waters in Jakarta to reduce floods from the Cilliwung River. Need for change The jointly compiled closing statement warned of the massive challenges facing deltas over the next 50 years. More comprehensive assessments of dynamic natural systems are required in order to establish the best measures for climate adaptation. The ad hoc studies that often form the basis for coastal engineering projects need to be replaced by integrated research and real-time monitoring of the entire system. This will allow for a better understanding of how assumed developments such as sea level rises and subsidence are taking place in practice. Vulnerability of deltas Gaele Rodenhuis, Chairman of the event: It became clear at Aquaterra that deltas are characterized by their exceptionally dynamic nature the place where the fresh water of rivers meets the salt water of sea, the low and high tides, the continuously moving shorelines and sedimentation. Rich clay ground, excellent fishing grounds and strategic locations for transport have turned deltas such as the Nile, Yellow River, أ قيمت الدورة الثانية ملؤمتر 2009 Aquaterra من 10 إلى 12 شباط )فبراير( املاضي في العاصمة الهولندية أمستردام. يتناول املؤمتر عد ة مواضيع تتعل ق بتطوير وإعادة تأهيل املناطق الساحلية ومناطق الدلتا عامليا. أم املؤمتر أكثر من 600 خبير عاملي في هذا املجال من جميع أنحاء العالم. تواجه مناطق الدلتا في العالم والتي ت عتبر األساس في قطاع إنتاج املأكوالت عامليا حتد يات متزايدة من التمدين وتطو ر قطاعات البنى التحتية والزراعة وذلك مع توق ع متركز 80 باملئة من سكان العالم في هذه املناطق في املستقبل القريب. كما تتفاقم هذه املشكلة مع إرتفاع مستوى مياه البحر ومشاكل إدارة مياه األمطار التي ي سب بها اإلحتباس احلراري وكان هذا املوضوع معرض بحث بني احلاضرين.

77 معارض ومؤمترات سابقة Event Review معارض ومؤمترات International training workshop on Design and Evaluation of Pressurized Irrigation Systems ended successfully in Lahore the workshop. Some of the participants made short presentations of state-of-the-art systems used in pressurized irrigation in their countries. On the last day of the workshop, certificates were distributed among the successful participants in the concluding session of the workshop. The Chief Guest of the Concluding Ceremony was Lt. General (Rtd) Muhammad Akram Khan, Vice Chancellor of the University of Engineering and Technology, Lahore. In his remarks, the chief guest urged the participants of the workshop to side by each other for help with the latest technologies like sprinkler and drip irrigation techniques. He also stated in his address that the common perception that future wars would be over water is not true since in reality such issues have already emerged in Muslim countries such as Jordan. Such unfortunate events are likely to be more intense in the future. He further remarks that a lot of potential exists in Muslim countries to handle the water scarcity issues in the coming years by adopting new technologies that best suit the conditions in these countries. The Center of Excellence in Water Resources Engineering, Lahore, Pakistan in cooperation with the Islamic Development Bank organized a five-day international training workshop on the Design and Evaluation of Pressurized Irrigation Systems for professionals working in the irrigated agriculture sector in the Muslim world from March 3 to 7, These systems are ideally studied for light and frequent irrigations. Major benefits of the pressurized irrigation systems are high efficiency and increased crop yield. The high initial cost of the system is off-set by increased yield and by increasing irrigated land with the same amount of water supply. The main focus of the workshop was to create close and long term liaisons among institutions of Islamic countries and to provide a forum to discuss the issues related to pressurized irrigation. Seventeen participants from nine Islamic Countries including: Bangladesh, Iran, Jordan, Malaysia, Oman, Saudi Arabia, Sudan, Syria, and the UAE, and more than thirty from Pakistan participated in the workshop. The workshop was inaugurated by Prof. Dr. Muhammad Ashraf, Dean of the Faculty of Civil Engineering.

88 info Word of the Expert كلمة اخلبير Treating municipal wastewater by reed bed wetlands By Dr. Eng. Darwish Ibrahim Yousef and Dr. Eng. Robin Yousef* One of the commonly found environmental problems in developing countries is water pollution caused by direct disposal of untreated municipal wastewater. Most of the centrally collected wastewater treatment plants are not functioning due to high cost of spare parts, chemical additives, utility bills and lack of trained human resources. These financial and managerial problems are common in every developing country. The use of natural systems in the treatment of liquid wastes has been getting substantial attention in many environmental conferences and forums. The use of plants, water, and soil in a composite unit generally called a wetland has been applied in many areas and applications from domestic to industrial waste sources. Other terms which refer in part or in general to natural treatment systems include: Land treatment, phytoremediation, constructed wetland, etc The realization of the importance of wetlands, which ecologists often refer to as nature s kidneys for their water cleansing capacity, has grown since the 1960s. The interest in this new and emerging field of Environmental Studies has led to a deeper understanding of the mechanisms and issues involved in its use. A significant and promising facet of this technology is the low energy requirement in its application. A natural treatment system would refer to any unit process, which would involve water, soil, plants, microorganisms, and interaction with the atmosphere. If we remove the plants from this equation, then this would refer to any of the conventional biological treatment systems we are familiar with. The addition of plants in this stoichiometry would therefore differentiate it from other systems. In an effort to apply rigidity to the study of this field of environmental engineering, different authors have come up with classifications for the different processes under the general label of natural treatment systems. We can generally classify them according to the following headings: (a) Aquatic Treatment Units; (b) Wetland Treatment Units; and (c) Terrestrial Treatment. Natural treatment systems, specifically constructed wetlands, provide a good and robust solution for the rising wastewater problem in the Middle East. Compared to common treatment facilities, wetlands are lower in cost investment, lesser to maintain, and are ideal for densely populated rural or suburban areas. terms of adjusting to excessive load. In the case of Engineered Reed Bed Systems, rhizodegradation is the main mechanism for the removal of organic contaminant. Rhizofiltration explains the retention of inorganic contaminants in the reed bed. The reeds which are used for reed bed construction are rhizome bearing macrophytes. These structures in the root system or rhizosphere provide the microenvironment for aerobic and anaerobic degradation of various compounds. Together with the root exudates from the reeds, a unique environment for degradation is produced. The other mechanisms also come into play in varying degrees. These mechanisms give the reed bed system a distinct advantage over other conventional biological systems in the degradation and stabilization of recalcitrant compounds and difficult-to-biodegrade or persistent compounds, which are often also toxic compounds. The advantages of Engineered Reed Treatment Systems include: (a) Minimal operating cost due to low energy required; (b) possible treatment solution for the removal of recalcitrant compounds; and (c) possible treatment solution for very small flows, previously untreated. The use of reeds for the treatment of sewage was first investigated in Germany by Seidel and Kickuth in the 1960s. Since then, about 500 reed bed treatment systems have been constructed in Western Europe since In general, the experiences gained in the years since, show that BOD (Biochemical Oxygen Demand) removal is 80 to 90%, with typical outlet concentrations of 20 ppm; total N removal is 20 to 30%; and total P removal is 30 to 40%. A general problem is surface flow of the feed caused by the hydraulic load exceeding the permeability of the bed. It is important to note that the pre-engineering of reed bed treatment systems is critical. These systems are not flexible in ي بني الدكتور درويش يوسف والدكتور روبني يوسف في هذه املقالة أهم ية تطبيق املعاجلة الطبيعية ملياه الصرف الصح ي عن طريق تقنية األراضي الرطبة امل نشأة من أسر ة القصب مشيرا إلى الفوائد االقتصادية والبيئية الناجمة عن تطبيقها على التدف قات الصغيرة على وجه خاص.
