Through a partnership between the government’s Department of Environmental Affairs and a water engineering firm, this project would develop grey-water treatment and distribution facilities to recover grey water from mosques in 3 pilot communities. In doing so, it would increase incomes by adding irrigated land and increasing water availability. To promote social acceptance and to increase understanding of grey-water reuse and sustainable water management, the project would conduct a public awareness campaign and seek the support of religious leaders, sheikhs, and government officials. In addition, the Department of Environmental Affairs would disseminate the project experience and results gained to other communities. This project expects to reduce groundwater extraction for agriculture and initiate an industry to reuse grey water throughout Yemen.
