Experience Note: Demonstrating the Suitability of Using Engineered Wetlands as a Low-cost Alternative for Treating Sanitary Sewage
2007: The Lake Manzala Engineered Wetlands Project (LMEWP) is a successful demonstration of the use of engineered wetlands to treat and reuse wastewater. The demonstration project has shown that engineered wetland treatment facilities constitute an effective, low-cost, low maintenance option and are well-suited for the climatic and operational conditions present in the Nile Delta of Egypt. Reduction rates of 61 % of BOD, 51% of Total Nitrogen and 99.7 % total Coliform bacteria have been collected at the project site, demonstrating a highly efficient technology. Treated water from the LMEWP can be safely and effectively used as a water source for fish farming and for safe disposal into Lake Manzala. These successes, if replicated in the area, will have a significant impact on the quality of local fish for human consumption, and will help to improve the water quality in Lake Manzala. LMEWP is contributing to an increasing interest across the Egyptian national government and several governorates to use low cost innovative treatment technologies (approximately 1/4 of the price of conventional treatment systems) to cope with the significant sewage treatment demands in Egypt.
