In August 2009 the North RSC functions were completely separated from the other RSCs and a DGM was appointed. An AGM was also put in place to provide support in running the RSC. O&M activities come under Jaffna Region and are managed by a regional manager. The main RSC functions are to provide necessary support to the regional office in the day to day O&M activities and to provide help and guidance in the existing scheme rehabilitation and augmentation work.

The O&M manager reports to the AGM. All RSC functions are monitored by the Additional General Manager for North & Central. The RSC is providing services to the regional offices within their capacity. Any additional help, if necessary is obtained from H/O through the respective Additional General Manager.

As this is a newly setup unit and due to the extraordinary situation that has prevailed for nearly three decades, the coverage of NWSDB in the North is limited. There are some medium scale schemes operational in Vavuniya and Mannar district. All other schemes in North RSC are very small scale water schemes.

The NWSDB is now taking steps to establish the North RSC as an independent unit, providing it with support in order to be able to widen and improve the services to the consumers in the North.
