The Water Sector is divided into two sub-sectors namely: Water Resources which is regulated by Water Basins and Water Supply and Sanitation. Provision of water supply and sanitation services is done through Water Supply and Sanitation Authorities (WSSAs) which are regulated by EWURA; and Community Owned Water Supply Organisations which are regulated by the Ministry of Water. The Water Supply and Sanitation Authorities are established in accordance to Section 91(a) of Water Supply and Sanitation Act, Cap 272 whereby the Minister responsible for Water may, in consultation with the Minister responsible for local Government, establish a WSS Authority based on criteria detailed in Water Supply and Sanitation Regulations, GN. No. 90 of 2013. Water Supply and Sanitation Authorities (WSSA’s) are responsible for management of water supply and sanitation services mostly in urban areas.
Regulation in the water sector started in 2006 after amending the Water Works Ordinance of 1949. A new Water Supply and Sanitation Act, Cap 272 came into operation in August 2009. The Act provides clear division of responsibilities between the Ministry of Water, Water Supply and Sanitation Authorities and EWURA. It also translates the 2002 National Water Policy into legislation.
Currently, EWURA regulates 130 Water Supply and Sanitation Authorities which provide water supply and sanitation services in Regional and District headquarters, Small towns and National Projects Water Authorities, as shown on a List of Regulated WSSAs declared by the Minister responsible for water and summarised below.
