3 Project Value Min 59 million Euros (depending on the treatment to apply) IFs The project is mentioned in the national wastewater strategy and was confirmed as a national priority through official communication with the promoter CDR National Strategy and NAP relevance Given its importance in terms of geographic location (on the Mediterranean coast) and the population it serves, the project is mentioned in the national strategy for wastewater management and NAP as a national priority. The Ghadir extension project was clearly mentioned under the NAP with a cost estimate. The government has initiated the preparation of technical designs in support to this project relating to the main collectors coming to the Treatment Plant. Furthermore has completed the construction of other main conveyors discharging to the existing preliminary WWTP. Relevance to H2020 The existing site is directly located on the sea shore and is to serve the Southern part of Beirut and a broader area of the Ghadir drainage basin with an increased population expected to reach 1.5 million by Up till recently main collectors of the Ghadir drainage area were still discharging directly to the Sea. It is now reported that some of these are now connected to the Plant. Yet, not all of the incoming flow is passing through the preliminary treatment works and is discharged directly to the sea through the short length, emergency sea outfall of the plant. The preliminary treated flow is discharged through the main, long sea outfall, with slightly reduced pollution load. Coastal pollution is being evidenced as well as non compliance with the respective regulatory requirements for wastewater discharges to the Med sea.

4 A. GENERAL INFORMATION A.1 A.2 A.3 A.4 Existing work / Current status Description of area Number of inhabitants Socio-economic status / activities The current facility comprises a preliminary treatment that provides sand and grit removal after incoming raw sewage is lifted and screened. The preliminary treated water is discharged by a main pumping station, a main, long, sea outfall and an emergency sea outfall. The water is discharged through the main sea outfall at a distance of 2.6 km from the coast and at a depth of 60 m. However this structure currently only serves low percentage of the total flow into the station leaving significant part of it discharged directly to the coast. The Ghadir drainage area is divided into 4 zones with different characteristics as follows: Z1 Aley: located between 400 and 900 altitude known as a summer destination Z2 Baabda: located between 250 and 400 altitude suburbs of Beirut and characterized as good standing Z3 Beirut, Southern Suburbs: Part of Beirut City it features working class districts and considerable concentration of migrants from the South and Bekaa Z4 Naame/Damour: located at 150 altitude 20 km from south Beirut which is growing very fast in terms of population due to its easy access 1,000,000 are served by the project (approximation of current population figure) Based on the above division of zones the socio-economic status is given hereunder for the different zones: Z1: Semi-Urban Area with around 50,000 population as employees, professionals or in the commercial sector Z2: Middle class settlements with around 40,000 population with agriculture as the prevailing economic activity Z3: Which includes the major Beirut quarters with its southern suburbs known to be the most crowded area with an estimated population of 700,000 with heterogeneous social structure reflected in the wide range of occupations and economic activities. Z4: described as a rural area that suffered from sever displacement during the war. The area is also characterized with high unemployment rates (85%) and 25% employed in the agriculture sector A.5 A.6 A.7 A.8 Drinking Water Systems Wastewater Collection Wastewater Treatment Institution(s) A parallel project on Awaili Basin, currently under development, deals with the drinking water systems of the Ghadir Drainage area. In the scope of the extension of the Ghadir WWTP, a separate component is foreseen to promote implementation of Awali project. Through this component, necessary information for the water supply systems of Ghadir will be retrieved and evaluated by the Feasibility study and the appraisal preparation for the Ghadir WWTP The Feasibility study conducted in 2000 for the Ghadir extension WWTP refers to main collectors that they are either missing or are not connected to the existing preliminary works at Ghadir. During the preparation of the ToR (interviews conducted with CDR, the site managers, GTZ and review of provided material) it was understood that some of the main conveyors are now completed and either connected or about to be connected to the WWTP, while for others the networks are under study by a parallel KfW study. It will be part of the inception phase of the Ghadir extension project to further clarify and update the existing situation regarding the wastewater collection of the drainage area. The current facility provides with preliminary treatment as mentioned above. Different treatment options have been suggested for the extension of the WWTP by the FS conducted in the year Anaerobic digestion combined with a system of long sea outfalls was the recommended as best option (from financial and technical point of view). The advantages of the method have been acknowledged; yet several reservations are still in place prompting for additional technical options to be assessed in the upcoming Feasibility Study for appraisal preparation of the extension of the Ghadir WWTP. Given the current situation the Institutions involved in this project are divided according to the different phases of the project. Accordingly for all works related to the preparation of the project that includes the tendering phase all the way till the construction and commissioning will be under CDR in cooperation with the Ministry of Energy and Water. Following the handing over of the construction works the Beirut and Mount Lebanon Water and Project Fact Sheet Page 4 of 16

6 B PROBLEM ANALYSIS B.1 The current facility comprises a preliminary treatment that provides sand and grit removal after incoming raw sewage is lifted and screened and final disposal through a long sea outfall, known to provide relatively good dispersion. However this structure currently only serves part of the total inflow to the station leaving most of the wastewater discharged directly to the sea, through either direct coastal outfalls or the emergency sea outfall of the station.. This direct sewage disposal in the Mediterranean sea is causing contamination of the sea resulting in public health threat. The sewage contamination is also deteriorating the marine ecological biosystem. The project is located on the southern coastal strip of Beirut. With the present discharge of treated and untreated sewage into the sea the area is a definite hotspot in terms of its impact on marine life, public health and the economy of the area in terms of tourism attraction C THE PROJECT C.1 PROJECT OVERVIEW Environmental As mentioned earlier the project proposes to eliminate all untreated sewage discharge to the sea eliminating sea water contamination and reducing substantially public health hazards. It will also allow for economic development of the area, through tourism development. Furthermore it will safeguard compliance with the environmental standards imposed by international conventions and national legislation, referring to wastewater discharges. Economical Economically the project has a direct impact on the national public health bill associated with water borne diseases. Moreover by treating the wastewater discharged to the sea and eliminating sea water pollution the project is improving the land value located in the vicinity of the facility that has direct economic benefits. Financial The project proposes two options: 1. Activated Sludge Process with Primary treatment for a total cost of US $226.7M (Euro 162M) 2. Activated Sludge Process with Anaerobic Pre-treatment with two sub-alternatives: a. Sub-Alternative 1: Anaerobic treatment with sea outfall for a total cost of US $83M (Euro 59M) b. Sub-Alternative 2: Anaerobic treatment with activated sludge tanks and settling tanks with sea outfall for a total cost of US $165.5M (Euro 118M) Institutional The project promoter will be the Council for Development and Reconstruction (CDR). CDR will undertake all discussions with EIB to include technical and financial. CDR will be the party responsible for the proper implementation of the project and the loan management. Upon project completion the project will be handed over to Beirut and Mount Lebanon Water Establishment for operations and maintenance. Technical The considerations of the above alternatives and the final decision should be based on several factors. Those factors are technical, environmental and financial. The most complicated technical operation with highest investment cost is the first option which according to the feasibility will have repercussions on the tariff structure requiring unaffordable tariffs by the community. As for options 2.a and 2.b the most affordable is 2.a since the investment cost is the lowest resulting in lower required tariffs. In addition it can build on the existing structure with no offshore land reclamation ad no disturbance of the surrounding beaches. Certain reservations have been expressed regarding the appropriateness of the sub-alternative 2a, related with its reduced efficiency, limited applicability for WWTPs of this scale and location related Project Fact Sheet Page 6 of 16

8 C.2 PROJECT BACKGROUND At the moment and with the existing infrastructure at the Ghadir WWTP the famous Ramlet El Baida beach, a beautiful white sandy beach, is being contaminated by sewage carried out by sea currents from the Ghadir. Given that there are people using this beach it is believed that they are prone to be affected by skin diseases and various infections. At the same time it is very difficult for the government to declare in public that the beach is polluted with sewage discharges. This will affect tourism in a negative way. As such the government is obliged to solve this problem through an integrated wastewater collection and treatment project. Currently the Ghadir river water course is serving as a main open sewer line for the towns and villages draining towards it. Moreover Lebanon is one of the signatory countries of the Mediterranean Action Plan (MAP) convention. The convention stipulates that signatory parties should abate pollution of the Mediterranean Sea from land-based sources and especially sewage discharges. Consequently the proposed extension of Ghadir WWTP will help Lebanon overcome this problem and meet its international commitments in protecting the Mediterranean Sea. C.3 PROJECT RATIONALE Project objectives / rationale As mentioned earlier, since Lebanon is signatory country of the MAP, this project will help Lebanon meets its international commitments. Consequently the project will provide the necessary infrastructure to treat wastewater and discharge it via a sea outfall into the sea insuring the safety of the 300 m bathing band defined by the MAP. Health risk related to bathing in coastal waters will be eliminated and sea food contamination will be attenuated. Moreover, if the project will not take place, the existing administrative and technical deficits in sanitation will lead to a widespread contamination of the sea and the coastal boundary of the project area affecting beach tourism negatively with direct impact on the economy. Consequently the project addresses to improve sanitary conditions by constructing proper wastewater collection and treatment facility. This will contribute to reducing diseases, to healthier population, to raising standard of living, to protecting the environment and to positively supporting the economy. Challenges Limitation of funds: This would lead to a partial implementation of the project components hindering meeting the intended objectives. No Reform in the Water Sector: This is a double fold challenge as it relates to the institutional structure of the created Beirut and Mount Lebanon Water and Wastewater Establishment that lacks the expertise on one hand and the tariff structure that is currently not sufficient (in fact nonexistence) to cover the cost of operation and maintenance. On the other hand. C.4 EXPECTED RESULTS Environmental If the project is implemented the following results can be foreseen: The wastewater treatment and disposal will ensure all along the shore from Khalde until Ras Beirut the safety of the 300 m bathing band defined by the MAP convention Health risks especially related to bathing in coastal waters will be eliminated Socio-economical Even though the project does not have a direct impact on poverty reduction, it is expected that a functioning sewerage and sanitation system including private household as well as industries will not only contribute to reduction of health hazards but will generally contribute to an improvement of living conditions in the area and improving opportunities for additional economic activities C.5 POLICY CONSTITUTIONS Evidence of commitment at local and national level The major evidence of national commitment is the initial serious steps undertaken by CDR to develop a full fledged feasibility study for the extension of Ghadir WWTP that was finalized in Moreover the CDR is currently procuring the services of a consultant to prepare technical designs for the main sewer and storm water collectors coming into the station as one conditional component for the success of the extension of the plant Project Fact Sheet Page 8 of 16

9 Demonstration value or significance in relation to sector development (WW, SW and/or IE) Linkage to sectoral policies, strategies and action plans Programme/ project approach The project once implemented will be directly contributing the implementation of the national strategy for wastewater. Moreover, the MAP convention, to which Lebanon is a signatory country, stipulates that signatory parties should abate pollution of the Mediterranean Sea from land-based sources and especially sewage discharges. Consequently the proposed extension of Ghadir WWTP will help Lebanon overcome this problem and meet its international commitments in protecting the Mediterranean Sea through improving wastewater management practices. The major evidence of national commitment is the initial serious steps undertaken by CDR to develop a full fledged feasibility study for the extension of Ghadir WWTP that was finalized in Moreover the CDR is currently procuring the services of a consultant to prepare technical designs for the main sewer and storm water collectors coming into the station as one conditional component for the success of the extension of the plant.. The financing negotiations of the project will be discussed with CDR and decisions of committing to the financing agreement should be issued through a law prepared by the Council of Ministers and approved by the parliament. CDR will lead the procurement of expertise and engineering services required for the implementation of the project. Moreover, CDR will supervise the project implementation and the management of the loan. Upon completion the project will be handed over to Beirut and Mount Lebanon Water and Wastewater Establishment (BMLWWE). BMLWWE will then be in charge of operating and maintaining the project. This could be either through their own structure or through subcontracting the private sector. C.6 INSTITUTIONAL Enforcement of environmental legislations Promoter: Environmental Legislation is in place for a number of aspects relevant to the Ghadir Project. Some of this legislation was developed after the FS of 2000 was completed. Enforcement of environmental legislation is questionable for certain aspects such as compliance with ELVs. It is important to note here that the promoter of this project will not be the one in charge of its operation once the project is completed. Consequently the assessment provided hereunder covers both the promoter in this case CDR, and the Future operator or in charge of operation, i.e. Beirut and Mount Lebanon Water and Wastewater Establishment. CDR: It is very well known that CDR possesses the right staff in terms of technical and contractual expertise. Most tender documents are prepared in house and staff, at the project and planning levels, are very competent in supervising project implementation. However the fact remains that CDR is practically understaffed and qualified staff are overworked. BMLWWE: Wastewater management and treatment is very recent in Lebanon. The newly created water Establishments still lack expertise and qualified staff in managing wastewater treatment plants, especially advanced ones like the one proposed under this project Assessment of promoter s capacity CDR possesses senior project management staff with wide experience in preparing and constructing water and wastewater projects. However, CDR perceives itself to be lacking in expertise in drawing up specifications for operation and maintenance. The Project Management Division of CDR is currently dealing with around 400 ongoing contracts for infrastructure projects of all types, with a combined value of around US$ 600 million. The Division has 24 senior project managers and other professional staff of all grades. The staff of the Division is heavily overloaded, with the result that delays to the processing of projects through the implementation sequence occur frequently. Project Fact Sheet Page 9 of 16

10 C.7 FINANCIAL Financial analysis overview: The total cot of investment shown in the table above does not include operation and maintenance and are manly restricted to civil works and equipment. Considering the present tariffs charged by the water establishments it is obvious that the introduction for sewerage and wastewater treatment services needs to be introduced. However this should also take into consideration the affordability of the different consumer groups. A parallel project run by GTZ is looking into tariffs structures and suggests specific alternatives to the competent Authorities. i.e. Ministry of Energy and Water as well as the WE. By treating the wastewater discharged to the sea and eliminating sea water pollution the project is improving the land value located in the vicinity of the facility that has direct economic benefits. As a matter of fact it is very evident that the currently un-attractive beaches are the main factor hindering the development of hotels and leisure resorts in the vicinity of the Ghadir project area. Moreover the feasibility study stipulates in the socio-economic survey that the majority of the population is well aware of the necessity of treating wastewater and more than half of the households interviewed indicated their general willingness to pay for this service. Last but not least, the Loan amount required will definitely be based on the treatment process selected. This can only be done after a thorough revision and update of the present feasibility study is conducted and new technologies assessed given the present situation. Loan amount Availability of government funding Financial sustainability IFI interest Donor interest (availability of grants) To be discussed To be discussed To be discussed To be discussed To be discussed C.8 TECHNICAL Status of studies and permits Additional studies and TA requirements C.9 SOCIO-ECONOMIC IMPACT A detailed feasibility study combining technical and financial analysis of the project was finalized in This study seems to be a comprehensive one however many aspects of the study at the financial, institutional, population and project area, infrastructure and land use developments, technical progress in wastewater treatment processes as well as legal requirements will need to be updated. The study also contains a specific section dedicated to EIA, considered by the CDR and the Ministry of Environment to be more of a screening (or even ToR) for an EIA report, rather than a full fledged EIA. EIA permit was never granted in the process of the previous Feasibility Study. Serious concerns were raised for the selected treatment option and the level of completeness of the submitted EIA report. As for permits, so far no permits or expropriation of land required for the proposed extension have been undertaken yet Review and update the project Feasibility Study with full analysis of technical and financial feasibility Preparation of an EIA for the project Preparation of ToR for Consultant to prepare Tender Documents for Design and Construction The project outputs are mainly environmental and social in nature. The project will help improve the life and health standards of the population in the project area. There will be a major improvement in environmental conditions with regards to present pollution of the sea and the coast Project Fact Sheet Page 10 of 16

11 The project has no direct impact on poverty reduction but will help the economy through the elimination of sea and coastal pollution hindering investments in beach resorts and attraction of tourism activities. C.10 ENVIRONMENTAL IMPACT Environmental analysis of the project implementation needs to be fully assessed once the decision has been taken on what option to pursue. Overall the environmental impact of the project will be positive to the aquatic environment and the population of the broader area, as it will prevent untreated municipal wastewater discharges for ending up to the Mediterranean Sea. Any adverse impacts that may arise during either the construction or the operation phases, will be examined by the Environmental Impact Assessment and where possible quantified through suitable assimilative models. Suitable preventive and/or mitigation measures will be suggested and integrated in the project development and implementation. Particular attention will be given to impacts related with air emissions and odours, land reclamation (land filling) if applicable and the management of the produced sludge. C.11 OPPORTUNITIES & RISKS Opportunities Risks Institutional Given the present willingness of the Beirut and Mount Lebanon Water and Wastewater Establishment to commit in providing dedicated staff for the wastewater sector we believe that this project will be a good start for such commitment to materialize with some technical assistance provided in the financing of the project. Human Resources With the implementation of the project and high probability that it will be managed by the private sector, dedicated staff from Beirut & Mount Lebanon Water and Wastewater Establishment (BMLWWE) should be assigned to accompany the works of the private sector in order to gain expertise and be trained in the fields of: 1. Operation, equipment performance, safety measures, treatment process, and automation of operations 2. Maintenance management for routine and preventive maintenance 3. Financial and personnel management, accounting and computer applications 4. Sludge types and characteristics as well as sludge treatment and disposal Relevance to country s policies / strategies Given its importance in terms of geographic location (on the Sea) and the population it serves, the project is mentioned in the national strategy for wastewater management and NAP as a national priority. Studies The feasibility study dated back in 2000 is a good piece and provides substantive information on the proposed works and project components with alternative options. The feasibility study and technical designs done provide with a good basis for the new feasibility study that needs to be conducted. Institutional Despite all the willingness expressed by the water establishment to provide staff for wastewater, the said staff and the wastewater expertise do not exist at the establishment to date. Accordingly, the financing of the project should take into consideration a technical assistance to the establishment in order to recruit the proper expertise and build their capacities in running such operations. Financial It is very well known that Lebanon so far has committed more that 1 billion US Dollars for the wastewater sector. This has resulted in some reluctance among the donor community and IFIs to further provide funds and financing for this sector. Moreover the existing tariff structure for water does not support proper cost recovery of wastewater operations. However it should be noted that the new law that created the new water establishments mandates those establishments to propose the tariff structure they see appropriate but the political will has not yet Project Fact Sheet Page 11 of 16

12 C.12 PROJECT READINESS Budget: Implementation plan matured for such a step. Yet, very recently some progress has been made in the definition of different scenaria for wastewater tariffs system through the GTZ project (provision of TA to the Water Sector in Lebanon). Human Resources Given that special staff should be dedicated for the wastewater operations at the water establishment, the risk would be the inability of the relevant water establishment to convince the government in obtaining necessary decrees for recruitment of new staff for such operations due to budget cuts or other political considerations. Technical A technical risk that should be carefully addressed at an early stage of the project is related with the inflow entering the WWTP. In terms of quantity it should be verified that adequate level of flow enters the plant to avoid situations experienced elsewhere whereby the lack of sufficiently developed network resulted in WWTPs being constructed but without being able to operate. Another issue is related with the type of flow that enters the plant as it is known that at least part of the Ghadir area drains sewerage and stormwater ultimately to the same conveyors entering the WWTP. Appropriate structures are reported to be in place to divert the flows accordingly; yet this should be clarified at the early stage of the project to ensure that optimum management of drainage water applies in the Ghadir area. Implementation plan Prepared in 2000 and will need updating Monitoring of implementation plan - Not ready yet Project Readiness The project is not ready yet and will need updating if the feasibility study, technical designs possibly and the EIA. Summary of gap analysis The following studies are required to prepare the project, including all activities involved in hiring and supervising consultants, such as prequalification, preparation of terms of reference and requests for proposals, tendering, proposal evaluation, contract negotiation, progress supervision and review of reports: Review and update the project Feasibility Study with full analysis of technical and financial feasibility Preparation of an EIA for the project Preparation of Terms of reference for a Consultant to prepare the Tender Documents for Design Construction Project Fact Sheet Page 12 of 16
