Common STP UGSS Tiruvallur - Proposed Wastewater Treatment Plant in Egattur, Tamil Nadu

Common STP UGSS Tiruvallur is a proposed wastewater treatment plant located in Egattur, Thiruvallur, Tamil Nadu, India. The facility is designed to serve a population of 41,423, classifying it as a medium-sized agglomeration under Indian urban wastewater management standards. The plant is part of the broader sanitation infrastructure for the region, aimed at improving wastewater collection and treatment. As a proposed facility, specific treatment processes and operational details are not yet finalized. In India, wastewater treatment plants of this scale typically employ secondary treatment technologies such as activated sludge or sequencing batch reactors, in compliance with the Central Pollution Control Board (CPCB) norms. The plant's designed capacity is 1.00 million liters per day, which aligns with the population served. The treated effluent is expected to be discharged into local water bodies, likely contributing to the drainage system of the Arani River basin, which flows into the Bay of Bengal. Proper treatment will help protect downstream ecosystems and reduce pollution in the region's water resources.

The plant is located in the Arani River basin, which drains into the Bay of Bengal. The downstream environment includes agricultural areas and coastal ecosystems that depend on clean water. Effective wastewater treatment is crucial to prevent nutrient loading and contamination of surface waters, supporting aquatic biodiversity and local livelihoods.
