About Us

System of Regional Support Centre (RSC) was established for smooth management of Operation & Maintenance (O&M) Section in 1992. This was a recommendation made by the Institutional Development Programme funded by USAID. At the inception, only four RSCs were established for Western, Southern, Central and North Central Provinces. All Water Supply Schemes (WSS) except Kalutara WSS were under the Western RSC. With the expansion of water supply facilities in Western Province, it was decided to divide Western RSC in to 3 RSCs in 2008. Accordingly, RSC- Western Central (WC) was established to coordinate activities related to the central part of Western Province.
At present, RSC-WC geographically covers all areas in Colombo District except Dehiwala-Mount Lavinia and Moratuwa Municipal Council Areas. It consists of 03 Municipal Councils (Colombo, Sri Jayawardhanapura & Kaduwela), 05 Urban Councils, 03 Pradeshiya Sabhas falling within 10 Divisional Secretary areas.
RSC-WC has the largest number of connections (about 560,000 as at August 2020) when compared to all other RSCs. It generates the highest income for NWS&DB.
