Water supply and sanitation in Senegal
From Wikipedia, the free encyclopedia
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, as the private partner. SDE does not own the water system but manages it on a 10-year lease contract with the Senegalese government. Between 1996 and 2014, water sales doubled to 131 million cubic meters per year and the number of household connections increased by 165% to more than 638,000. According to the World Bank, "the Senegal case is regarded as a model of public-private partnership in sub-Saharan Africa".[5] A national sanitation company is in charge of sewerage, wastewater treatment and stormwater drainage, which is modeled upon the national sanitation company of Tunisia and is unique in Sub-Saharan Africa.
