National Water and Sewerage Corporation (NWSC) is a water supply and sanitation company in Uganda. It is wholly owned by the government of Uganda.
NWSC was formed by Decree No. 34 in 1972 to serve the urban areas of Kampala, Entebbe, and Jinja. In 1995, NWSC was re-organized under the NWSC Statute. The company was given more authority and autonomy and the mandate to operate and provide water and sewerage services in areas entrusted to it, on a sound commercial and viable basis.
