Department Of Water And Sanitation Nepal, The Department of Water Supply and Sewerage (DWSS), established in 1972, is the lead agency for the drinking water supply and sanitation sector of Nepal. It is working towards achieving the sector objective of the Government of Nepal which is to achieve ‘sustained improvement in health status and productivity for Nepalese people as a whole with particular emphasis on lower income group through the provision of adequate, locally sustainable water supply and sanitation facilities in association with improved personal, household and community hygiene behavior’.

DWSS is acting as the lead government department to achieve this target with the following broad objectives:

1. Provide and ensure safe, convenient, and adequate water supply to all Nepalese, with sanitation as an integral component, and with a specific focus on disadvantaged groups;
2. Reduce the incidence of water-related dieses prevalent in the country; and
3. Reduce suffering and drudgery of women and children, traditionally responsible for collecting water and domestic sanitation and hygiene.
