STP Town Panchayat Sriperumbudur is a proposed municipal wastewater treatment plant located in Sriperumbudur, Kanchipuram district, Tamil Nadu, India. The facility is designed to serve a population of 56,790, placing it in the medium-agglomeration category under Indian urban wastewater management frameworks. As a proposed plant, its treatment process and level are not yet finalized. However, Indian environmental regulations, including the Water (Prevention and Control of Pollution) Act, 1974, and the National Green Tribunal directives, typically require secondary or tertiary treatment for plants serving populations over 50,000, especially in water-stressed regions like Tamil Nadu. The plant's designed capacity is 1.00 million liters per day, which aligns with the projected population load. The plant will discharge treated wastewater into local water bodies that eventually drain into the Bay of Bengal via the Palar River basin. The region faces water scarcity and groundwater depletion, making treated wastewater reuse a critical component for local agriculture and industrial needs. The plant's operation will help reduce pollution in downstream ecosystems and support sustainable water management in the Chennai metropolitan area.
Environmental context
The plant is located in the Palar River basin, which drains into the Bay of Bengal. The downstream environment includes agricultural areas and the Chennai coastal ecosystem, which supports diverse aquatic life and is important for local fisheries. Treated wastewater discharge must meet stringent standards to protect these sensitive habitats from nutrient pollution and pathogens.
Frequently asked questions
The plant is located in Sriperumbudur, Kanchipuram district, Tamil Nadu, India, with coordinates 12.98° N, 79.946° E.
The plant is designed to serve a population of 56,790, classifying it as a medium-sized agglomeration under Indian urban wastewater standards.
The plant has a designed capacity of 1.00 million liters per day, which is appropriate for the projected wastewater generation from the served population.
The plant operates under India's Water (Prevention and Control of Pollution) Act, 1974, and is subject to standards set by the Tamil Nadu Pollution Control Board. For agglomerations of this size, secondary treatment is typically required, with possible tertiary treatment for water reuse.
In India, wastewater treatment plants serving populations of 50,000-100,000 usually employ secondary treatment processes such as activated sludge or sequencing batch reactors. Tertiary treatment may be added for reuse in agriculture or industry, especially in water-scarce regions like Tamil Nadu.
