Cairo water

The project, to be implemented by the General Organization for Greater Cairo Water Supply (GOGCWS), will enable new or improved water service to 600,000 people by expanding the capacity of the Rod El Farag Water Treatment Plant, laying transmission lines, and installing house connections. To expand Rod El Farag capacity by 200,000 cu m/day, a new raw water intake facility will be installed and the plant"s raw water pumping station will be modernized. New flash mixing and mechanical flocculation basins will be constructed, while existing clarifiers and sedimentation tanks will be modified to improve flow characteristics. New chemical storage and chlorination stations, a filtered water pump station, and office, residential, and laboratory facilities will be constructed, the latter to provide services for biological analysis and the treatment of heavy metals and pesticides as well as daily testing. Two cement-lined, ductile iron transmission lines totaling 5 km will be constructed and linked to existing mains in Cairo"s Shoubra, Rod El Farag, and Sahel districts. To provide indoor public water supplies and waste disposal systems in low-income areas, 40,000 metered house connections will be installed, each to include a floor sink and drainline to transfer wastewater to existing seepage pits or other disposal points. Amendment No. 1 of 6/81 will increase Rod El Farag capacity by an additional 250,000 cu m/d. The plant will be converted to a solids contact clarification system and the project as revised will provide all new equipment: raw water intake and pump station; chemical feeding and handling systems, solids contact clarifiers, filtering units, a filtered water pumping station, a backwash station, an administration building, and 6 km of transmission lines. Of the total 450,000 cu m/d increase in water produced, 270,000 will be available for residential use; beneficiaries will number at least 1.35 million. Facilities to handle the 300,000 cu m/d of increased wastewater flows resulting from the expansion will be provided under the Cairo Sewerage Project (2630091). GOGCWS personnel will be provided in-country and U.S. management training. The house connections element has been terminated, at least for the time being, due to implementation problems. (PD-AAI-100) Amendment No. 2 of 7/82 increases funding.
