Krishnagiri Municipality Wastewater Treatment Plant, Tamil Nadu

Krishnagiri Municipality wastewater treatment plant is located in Krishnagiri, Tamil Nadu, India, serving a population of approximately 61,400. The plant is operational and manages municipal wastewater from the city, contributing to local sanitation and water quality. As a medium-sized agglomeration, the plant operates under India's Water (Prevention and Control of Pollution) Act, 1974, and the Environment Protection Act, 1986. These regulations require appropriate treatment to meet discharge standards set by the Tamil Nadu Pollution Control Board (TNPCB). Typical treatment for plants of this scale includes secondary biological processes such as activated sludge or sequential batch reactors. The treated effluent is likely discharged into local water bodies that drain into the Ponnaiyar River basin, which flows into the Bay of Bengal. The plant plays a key role in protecting downstream ecosystems and maintaining water quality in the region's rivers and coastal areas.

The plant's treated effluent likely enters local streams that feed into the Ponnaiyar River, which flows eastward through Tamil Nadu and discharges into the Bay of Bengal near Cuddalore. The downstream environment supports diverse aquatic life and is important for local fisheries and agriculture. Protecting this watershed from untreated sewage is critical for maintaining water quality and ecosystem health in the Ponnaiyar basin and the Bay of Bengal.
