Overview
DWASA Dasherkandi Sewerage Treatment Plant (DSTP) is an operational municipal facility in Dasherkandi, Bangladesh, serving the Dhaka metropolitan area. It treats wastewater before discharge into local water bodies.
The DWASA Dasherkandi Sewerage Treatment Plant (DSTP) is a key municipal wastewater facility located in Dasherkandi, on the outskirts of Dhaka, Bangladesh. It serves the densely populated capital region, addressing sanitation needs for millions of residents. The plant is operated by Dhaka Water Supply and Sewerage Authority (DWASA) and is part of the city's expanding sewerage network. As a major treatment plant in a rapidly urbanizing area, it operates under Bangladesh's national environmental regulations, which mandate treatment for municipal wastewater. Plants of this scale typically employ secondary or tertiary treatment to meet effluent standards. The facility plays a crucial role in reducing pollution loads from Dhaka's domestic and industrial sources. The treated effluent is discharged into the Balu River, a tributary of the Shitalakshya River, which eventually flows into the Meghna River and then the Bay of Bengal. This discharge impacts the local aquatic ecosystem and downstream communities, making effective treatment essential for public health and environmental protection.
Environmental context
The plant discharges into the Balu River, which flows into the Shitalakshya River, a major waterway in central Bangladesh. The Shitalakshya joins the Meghna River, one of the largest rivers in the country, before emptying into the Bay of Bengal. This watershed supports diverse aquatic life and provides water for irrigation, fishing, and domestic use. The area is ecologically sensitive due to high population density and industrial activity, requiring robust wastewater treatment to prevent eutrophication and contamination.
