Serampore at Jannagar Road Serampore Wastewater Treatment Plant, West Bengal

The Serampore at Jannagar Road Serampore wastewater treatment plant is located in Serampore, a city in the Hooghly district of West Bengal, India, within the densely populated Kolkata Metropolitan Area. The plant serves a population of approximately 126,208, classifying it as a large agglomeration under Indian urban wastewater management standards. As an operational facility, the plant is subject to India's environmental regulations, including the Water (Prevention and Control of Pollution) Act, 1974, and the National Green Tribunal guidelines. For a plant of this scale, secondary treatment is typically required, and the treated effluent must meet prescribed discharge standards before release into surface waters. The treated wastewater from the plant is discharged into the Hooghly River, a major distributary of the Ganges. The Hooghly flows through the Sundarbans delta before emptying into the Bay of Bengal. This region supports diverse aquatic life and is an important migratory corridor for fish and birds, making effective treatment crucial for downstream ecological health.

The plant discharges into the Hooghly River, which flows through the Sundarbans delta and ultimately reaches the Bay of Bengal. The Hooghly is a vital water source for the region, supporting agriculture, fisheries, and domestic use. The downstream Sundarbans mangrove forest is an ecologically sensitive area that relies on adequate water quality from upstream sources. Proper treatment at this plant helps mitigate nutrient loading and pathogen contamination, protecting both human communities and the rich biodiversity of the delta.
