Drinking water supply and sanitation in Benin has been subject to considerable progress since the 1990s, in particular in rural areas, where coverage is higher than in many other African countries, and almost all development partners follow a national demand-responsive strategy, which has been adopted in 1992. New strategies to increase water supply in rural and urban areas have been adopted in 2005 and 2006. Tariffs in urban and rural areas are usually high enough to cover the costs for operation and maintenance.
