DESWSP project is designed to collect raw water from the Meghna River, treat the water in a treatment plant at Gandharbpur, and supply the treated water to the Dhaka city dwellers, mostly in Uttara, Gulshan, Baridhara and North Badda, through the DWASA distribution system.

The principal aim is to enhance the use of raw surface water sources and thereby decrease reliance on abstraction of underground water.
