Water supply and sanitation in Senegal is characterized by a relatively-high level of access compared to most of sub-Saharan Africa. A public–private partnership (PPP) has operated in Senegal since 1996, with Senegalaise des Eaux (SDE, a subsidiary of Saur International) the private partner. SDE does not own the water system, but manages it on a 10-year lease from the Senegalese government. Between 1996 and 2014, water sales doubled to 131 million cubic meters per year; the number of household connections increased by 165 percent, to over 638,000. According to the World Bank, "The Senegal case is regarded as a model of public-private partnership in sub-Saharan Africa". A national sanitation company is in charge of sewerage, wastewater treatment and stormwater drainage, which is modeled on the national sanitation company of Tunisia and is unique in sub-Saharan Africa.
