1 Water Conveyance Capability Statement

2 Introduction The Advisory Group Water Conveyance offers engineering advisory services for water transport systems. These services include master planning, feasibility studies, technical design, process monitoring and control, dashboard solutions and asset management. The Advisory Group Water Conveyance is part of the Business Line Water Technology of Royal HaskoningDHV. The Business Line Water Technology offers services related to the entire water cycle from drinking water treatment to water distribution to urban and rural populations as well as industries. On the wastewater side it covers sewage collection and treatment, including recycling treated effluent to the urban water cycle. Urban drainage and water management advisory services are also available. Since the company was established in 1881, Royal HaskoningDHV has gained more than 135 years of experience with water conveyance technology, which includes over 50 years of experience on international projects. Our clients include water boards provinces municipalities and many national and multinational clients in the private sector. Our services vary from strategic advice, policy formulation, feasibility studies, detailed engineering designs (including preparation of tender documents and cost estimating), construction supervision and management advice. Our Water Conveyance engineers are specialists in stateof-the-art water conveyance technology and continuously work to be at the leading edge of their specialisation. Royal HaskoningDHV works in multidisciplinary project teams who work with their clients to formulate and implement tailor-made solutions. The project activities we carry out in the field of Water Conveyance are identified in three main fields of expertise. Water Transport Systems - Pipelines - Water distribution networks - Wastewater Transport - Canals - Reservoirs Pumping Stations - Booster stations - (Sea water) Intakes and outfalls for industrial plants - Surface water and drainage pumping stations Operational Control - Asset Management of (waste-) water systems - Monitoring, performance indicators and analysis - Process control

3 Water Transport Systems Water Conveyance is interpreted as transport of large volumes of water. Due to its weight, the transportation of water is very energy intensive. Unless it has the assistance of gravity, a canal or long-distance pipeline will need pumping stations at regular intervals. It is therefore essential to pay close attention to design energy efficient pipeline systems to obtain minimum life cycle costs. Pipelines and hydraulic modelling Royal HaskoningDHV has developed dedicated tools to assess optimum pipeline design and pumping characteristics. We use sophisticated computer software to develop and design optimum solutions for water transport systems that are capable of dealing with all operational conditions. When the initial design is fixed, we use mathematical models for pipeline hydrodynamics, such as Wanda Liquid, Infoworks and Synergee. These tools are being used, among others, in order to check pump performance during emergency situations and to test pump and valve control. By applying these tools, we can test all operating conditions and emergency situations and thereby verify and improve the designs. For example; the Dutch water utility company Evides utilises a complex 130 km long water transmission system for their water transport. To ensure optimum reliability of this system, Royal HaskoningDHV built a full hydraulic model of this transmission system and its control and conducted a series of simulations to test the system on various operational situations and conditions. The innovative approach of hydraulic computer modelling incorporating fieldmeasurements and control components has resulted in a stable system gaining benefits both for the operator and the various consumers. Water Distribution In the Netherlands, Royal HaskoningDHV intensively co-operates with water utility companies in design and optimization of pumping stations and distribution networks. Water distribution networks represent more than half of the fixed assets of a drinking water utility. Its performance has a direct effect on each customer, in terms of both water quality and reliability of supply. Royal HaskoningDHV provides consultancy services on water network design, at a conceptual level and at detailed street level. We act as consultant, risk analyst, trainer and as design team. At a conceptual level, master plans and long term investment plans are made based on analysis of demand scenarios, raw water sources, existing water network and other water infrastructure. Many of our projects cover a supply area of more than one million inhabitants. At street level we optimize network layout based on customer demand, fire demand, required pressure, minimum flow velocity and specific demands of the municipality. Depending on the situation or client wishes, Royal HaskoningDHV can apply several hydraulic software packages (e.g. Infoworks WS, SynerGEE Water, WaterGEMS, Aleid and Epanet). Infoworks WS, is the main hydraulic software package applied for drinking water distribution in the Netherlands. More than 50% of all networks use Infoworks WS, followed by SynerGEE in 30% of the cases. Royal HaskoningDHV has developed hydraulic distribution models that cover a combined population of over three million people. These models use field measurement data to obtain realistic simulations of the system s performance. We provide regular training to the end users to enable them to use all tools and options available in these software packages. Water Transport Power Consumption An important aspect in the design of water transport systems is the optimisation of pump performance to reduce energy costs needed for transport of water. Royal HaskoningDHV uses a dedicated module within Wanda to optimize the use of the pumps installed in the pumping station. Energy savings are maximised by optimised pump operations. OPIR, which was developed in-house, is an advanced control software product which optimises the operation of water production and transport. It prevents turbidity peaks in clean water transport and reduces energy consumption of water transport. Hence, it improves water quality while minimising water production costs. It is the product of decades of experience with control systems in numerous water supply systems and is based on in-depth knowledge of production and distribution processes. OPIR s adaptive demand forecast allows for constant water production through the optimal use of the available water storage. OPIR can optimise the operation of any water transport system: urban or rural, large or small, basic or complicated, with or without SCADA. OPIR provides tailored and plantbased solutions. Currently 70% of the Dutch water supply companies use OPIR including for instance the city of Amsterdam. Outside The Netherlands, OPIR is already being used in Canada, Belgium, Poland and Portugal. Wastewater Transport Design of wastewater transport systems is a complex process considering that besides wastewater also solids and gas are transported. Special attention needs to be paid to the design to prevent sedimentation in the pressure line, clogging of pumps and accumulation of gas at high points in the pressure lines. Royal HaskoningDHV has participated with Technical University of Delft and Deltares in an 8 year programme called CAPWAT, investigating the effects of gas in wastewater transport systems. This successful programme resulted in new insights in flow phenomena and new design guidelines for wastewater transport systems, which is being used in our design work ensuring reliable and economic design solutions.

4 Pumping Stations Almost any water supply or wastewater collection system needs pumping stations to get water from one place to another. The pumping station should therefore be seen as an integral part of the larger water transportation system, requiring the same meticulous analyse of optimum hydraulic functioning and energy efficiency. Main and Booster Pumping Stations Main pumping stations, which supply water to distribution systems, are usually located near a water treatment or a potable water storage facility. Booster pumps, on the other hand, are additional pumps used to increase pressure locally or temporarily. Operating these complex pump systems requires dedicated design of the pump and valve control system in order to obtain a robust system while mitigating operating risk of water hammer effects. We use dedicated software to analyse the dynamic behaviour of the transport system and design anti-surge measures. The energy cost is one of the largest cost components in the water supply system. It is indispensable that water transport and distribution systems are planned and designed properly and that choice and design of pumps are such that the degree of efficiency of the system is very high. Royal HaskoningDHV has designed countless pumping stations ensuring optimum system performance and high efficiency of pumping operations. Surface Water Pumping Stations Surface water pumping stations play an important role in the Netherlands. Control of surface water levels fully depends on the proper functioning of these pumps as well as the transport and storage capacity of the overall water system. The pumps are designed for day to day use but must also be able to function under extreme conditions. To find the most cost effective solutions, Royal HaskoningDHV takes the overall system performance into account. By analysing the overall water system in an integrated model, optimum solutions can be obtained. The integrated model addresses all components of the water system by their hydraulic characteristics such as canal dimension, pump curves, rotation speed of the pumps, elevations of the lake and polders, etc. By simulating all possible operating conditions and analysing the dynamic behaviour of the overall water system, proper functioning of the pumping station can be verified and optimised. Three-dimensional images are compiled to ensure that everything fits during construction in the limited space within pumping stations of sometimes historical value. Royal HaskoningDHV works with their clients to reach optimum design, applying the latest techniques meeting water pumping requirements and upholding historical values. Royal HaskoningDHV conducts studies, performs conceptual and detailed design and carries out quality control during project construction. Sea Intakes and Outfalls Royal HaskoningDHV has extensive experience with marine pipelines, outfalls and intakes, having been involved in over 70 of such systems worldwide during the past 40 years. Royal HaskoningDHV has detailed knowledge of the whole spectrum of issues from the planning and consenting process to determining the hydrodynamic climate, through to outline and detailed engineering. Additionally, Royal HaskoningDHV has unparalleled knowledge of coastal process engineering in the marine environment. Our experts have substantial experience of design techniques and knowledge of the full range of materials and construction methods related to the wide variety of options available. Royal HaskoningDHV provides flexible, practical solutions targeted at satisfying the requirements of our clients in order to maximise value whilst providing robust results; the aim is to develop innovative environmental and engineering solutions.

5 Operational Control Asset Management of (waste-) water systems Transport systems are capital intensive infrastructure systems that have to last for decades. However, with time, pipeline systems deteriorate due to aging, overloading, misuse and mismanagement. Proper operation and maintenance of these systems, together with well-timed rehabilitation, can ensure long life of the infrastructure and delivery of reliable water transport services. If the infrastructure passed its economic life, the owner requires information on the remaining lifetime of the assets to decide on future investments and to obtain a reliable financial plan. Monitoring, performance indicators and analysis Having insight in the actual performance of pumps and pressure lines of water transport systems, in relation to what is expected based on the as-built design or theoretical model simulations, is becoming increasingly important. Although most monitoring systems provide data on flow rates and pressure, these monitoring systems do not directly give dedicated information on how well the water transport process is performing. Performance indicators have been developed for which the signals received from instruments are processed and changed into valuable information that can be used to directly aid the decision making of operators and managers. Asset management is a tool that provides optimum decisions on maintenance practice, on-going operations and on the planning of large investments associated with pipeline rehabilitation and replacement. Decisions (e.g. rehabilitation, maintenance) are made based on the available information, experience and risk-assessment. Our asset management services in the field of transport system management include: n the establishment of inspection plans for pumping stations and pressure pipelines, n assessment of CCTV inspection images, n preparing repair plans (including relining of concrete sewers) and replacement plans. This useful information and insight is only obtained by analysing process data. Questions regarding best optimum pump efficiency (i.e. lowest energy consumption), increase of hydraulic resistance of the pipeline (wastewater) and aging of the pump are some of the issues that requires comprehensive knowledge and understanding of the operation of transport systems in order to be resolved. The design and implementation of monitoring programs and dedicated performance indicators is a complex matter, in which automation issues, organization and practical implementation play a role. Royal HaskoningDHV has experienced specialists in this field and has been involved in the implementation of monitoring programs for drinking water companies, governmental organisations (municipalities and water boards). Services we offer are: n preparation of strategic monitoring plans, n designing dedicated performance indicators, n implementation of measurement locations, n utomated analysis of the acquired monitoring data. Royal HaskoningDHV has developed software called Aquasuite that incorporates several modules for monitoring, analysing and controlling processes for water distribution, transport, treatment plants and sewerage systems. One of these modules is OPIR, which was described above. Another module related to water conveyance is iwatt. iwatt is a unique tool that provides performance indicators for (waste) water transport systems. The iwatt module (i.e. Intelligent WATer Transport) provides a dashboard for the operator to view the performance of: n pumps, - with respect to deviation of duty points, - power consumption - potential maximum flow n Pipelines - Hydraulic resistance n Statistics - Sewage supply (from sewer systems) - Flow rates of pumping station - Deviations
