The Project components includes 3 main components: i. Wastewater Treatment Plant Expansion ii. Institutional Support and Sanitation & Hygiene Promotion iii. Engineering Services
Component I- Wastewater Treatment Plant Expansion: The outputs of this component comprise the construction of primary and final settlement tanks, aeration chambers, and sludge handling works, disinfection facilities and all related electro-mechanical works. Ancillary works will comprise sewage conveyance channels, access roads and administrative buildings. The average capacity throughout the treatment process will be at least 500,000 m3/d of wastewater, though alternative designs proposed by contractors could increase this by 25% or more. The contractor will design, build and commission, and then operate and maintain the plant for a twenty-four months period, as well as build the capacity of the plant operators. These works will be undertaken as one contract.
The treatment process will comprise pre-treatment, primary and secondary treatment. The incoming influent will be lifted through a 5 screw pumps each with capacity of 9,180 m3/h. to the pretreatment facilities where the largest solids will be removed using medium bar automatic screens sand and grease removal tanks, sand classifiers and grease separators. The wastewater shall then be lifted again by similar pumping arrangements into primary treatment tanks. All the materials that can easily be settled are removed in primary settlement tanks.
From primary treatment, the wastewater goes for secondary treatment, where it undergoes biological treatment comprising extended aeration. This is done by using air compressors and special bubble diffusers. The liquid is then settled in final clarifiers from where part of the activated sludge is recycled by pumping it to the head of the treatment plant while the bulk goes for digestion. Methane gas (CH4) is a byproduct of sludge digestion and is used to generate electricity, to meet up to 70% of the energy consumption at the treatment plant. Finally the effluent from the plant is chlorinated before being released into the drainage system, which leads it to Lake Manzala and eventually into the Mediterranean Sea. A small portion of the effluent is used for watering the treatment plant compound.
Component II - Institutional Support and Sanitation & Hygiene Promotion
This will cover institutional support that will be provided in form of training and capacity building of the staff of both CAPW and GCSDC in operation and maintenance of the wastewater treatment plant, including effluent disposal and sludge management. The component also provides for strengthening these institutions in the management of the health, social and environment aspects of such developments. This latter support is tailored for training the staff of CAPW and GCSDC to manage the social, health and environmental issues in the project site and its surroundings. To be able to do so, sensitization of the staff on environmental protection, improved sanitation and hygiene as well as gender issues will also be provided. The trained staffs will then conduct awareness campaigns among local communities living downstream along the drainage system, and sensitize them on these issues. As part of this public awareness campaign programme, the communities and agricultural committee members will be sensitized on the merits of the project and address issues on waterborne diseases, minimization of water pollution and dependence on polluted surface water, and on the improvement of health and social welfare. In addition, regular public consultation will be maintained throughout the project implementation period. Logistical and operational support to the Project Implementation Team (PIT) in implementing the project activities is included. In addition, this component also includes annual Project audit. An independent Auditor will be recruited to audit the project accounts annually.
Component III - Engineering Consultancy Services: An engineering consultancy firm will be recruited to review both conceptual designs and bid documents, which have already been prepared. The firm will then assist with the procurement of the works' contract and thereafter supervise the construction. Besides providing day to day supervision of the works, the consultant shall also provide on-the-job training to local staff. The Consultant will also ensure that complete O&M manuals are prepared by the contractor, take part during project commissioning, assist with the preparation of the project completion report, and provide support to the client during the operation period of the plant by the contractor. During the entire project implementation period, both the consultant and the contractor will train the staff of the executing agency for technology transfer. The consultant will prepare the training programme.
The project objective is to improve the quality of wastewater discharged into the drainage system in Cairo East, thereby contributing to increased coverage of improved sanitation and clean environment for the nearly 8 million population living in this area. The project entails construction of the next phase of GAWWTP (Stage II Phase II). This phase will provide an additional wastewater treatment capacity of 500,000 m3/d.
1. The importance of the water and sanitation sector to the economy of Egypt is demonstrated by the inclusion of the WSS sector in the Development Agenda of GOE. These include a) environmental protection and b) directing development towards desert land and correcting spatial imbalance. The pursuit of the development agenda and the achievement of the expected outcomes are being guided by the ten points action programme. The points are contained in the Government's statement presented to Parliament by the Prime Minister in December 2004, and re-affirmed in the Government's Policy Statement issued in January 2006. Some of the ten points supported by the proposed project include:
(i) protection of natural resources;
(ii) investment and employment;
(iii) enhancing economic performance; and
(iv)developing basic public services. The current access to water supply is 98% while only 66% benefit from improved sanitation.
2The objective of the Bank Group's assistance strategy in Egypt during 2007-2011 is to support the implementation of GOE's development agenda. According to the CSP 2007-2011, the Bank will, support, among others, Pillar I - infrastructure development (in energy, water and sanitation, transport) critical for enhancing the efficient functioning of the private sector. The project therefore falls within the Bank's Strategy for support for Egypt as elaborated in the CSP. Furthermore, the proposed project is clearly spelled out in the updated CSP MTR progress report, under Pillar I (Infrastructure - water and sanitation).
3The Bank's intervention is justified for the following reasons: 1) The Bank has a long standing successful relation and experience in the water supply and sanitation sector in Africa and is therefore in a position to contribute to the sectors development in Egypt 2) Egypt is a water scarce country and the degradation of water quality is a major problem as it affects all sectors of the country's economy 3) The country's progress towards reaching the MDGs in water supply is well on track while extra effort is required to reach the MDGs for sanitation.
The GAWWTP, whose expansion is the subject of this report is located in Cairo East. The plant's catchment area occupies the greater part of this part of the City, and is serving a population of approximately 8 million people. When completed, the proposed additional treatment capacity of 500,000m3/d will serve approximately 2.5 million more people in Cairo East. For these people, the project will provide a clean environment through safe wastewater disposal. Other beneficiaries of the project include people living in villages downstream of the plant and along the system draining the effluent from the plant into Lake Manzala, with an estimated population of more than 785,800. These families will also benefit from an improved environment and consequent reduction of diseases associated with untreated wastewater.
