National Water Supply and Drainage Board

The National Water Supply and Drainage Board (commonly abbreviated as NWSDB) is the National Organization responsible for the provision of safe drinking water and facilitating the provision of sanitation to the people in Sri Lanka. The organization had its beginning as a sub department under the Public Works Department for water supply and drainage. In 1965, it became a division under the Ministry of Local Government. From 1970, this division functioned as a separate department under the Ministry of Irrigation, Power and Highways and remained so until the present board was established in January 1975 by an act of Parliament of Sri Lanka.
