Dubrayapet Puducherry Wastewater Treatment Plant, Puducherry, India

Dubrayapet Puducherry is a wastewater treatment plant currently under construction in the city of Puducherry, India. Located near the Indhra Gandhi Sports Complex on Cuddalore Road, the facility is designed to serve a population of approximately 113,580, placing it in the category of a large agglomeration under Indian urban wastewater standards. As the plant is still under construction, its treatment process and capacity details are not yet finalized. In India, wastewater treatment plants serving populations over 100,000 are typically required to provide secondary treatment at minimum, with many moving toward tertiary treatment to meet increasingly stringent discharge standards. The plant's designed capacity is 1.00 million liters per day, indicating a significant infrastructure investment for the region. The plant is situated within 50 km of the coast, and its treated effluent will likely discharge into local water bodies that drain into the Bay of Bengal. Puducherry's coastal location means that proper wastewater treatment is critical to protect marine ecosystems and public health. The facility will play a key role in reducing pollution in the region's rivers and coastal waters.

Puducherry lies on the Coromandel Coast of the Bay of Bengal, with local rivers such as the Gingee and Pennaiyar draining into the sea. The plant's discharge will ultimately reach the Bay of Bengal, a biologically productive marine environment supporting fisheries and diverse aquatic life. Proper treatment is essential to prevent eutrophication and protect coastal ecosystems from nutrient pollution.
