Sewage Treatment Plant Thirumazhisai Town Panchayat - Proposed Facility in Agaram Mel, Tamil Nadu

Sewage Treatment Plant Thirumazhisai Town Panchayat is a proposed municipal wastewater facility located in Agaram Mel, near Nazarathpet, in the Poonamallee area of Thiruvallur district, Tamil Nadu, India. The plant is designed to serve a population of 20,044, placing it in the medium-agglomeration category under Indian urban wastewater management norms. As a proposed plant, its treatment process and capacity details are not yet finalized. However, under India's National Green Tribunal and Central Pollution Control Board guidelines, sewage treatment plants serving populations of this scale are typically required to meet secondary treatment standards, with potential for tertiary treatment if the receiving water body is sensitive. The designed capacity volume is 1.00 million liters per day, indicating a facility sized for the projected community needs. The plant's treated effluent will likely be discharged into local water bodies that drain into the Bay of Bengal via the Palar River basin or nearby coastal streams. Proper treatment is essential to protect downstream ecosystems and groundwater quality in the region, which supports agriculture and urban settlements. The facility's operation will be subject to state-level pollution control board permits and monitoring.

The plant is located inland, approximately 50 km from the Bay of Bengal coast, in the Palar River basin. Treated wastewater will likely be discharged into local streams that eventually drain into the Bay of Bengal, affecting coastal water quality and marine biodiversity. The region's semi-arid climate and reliance on groundwater for drinking and irrigation make effective treatment crucial to prevent contamination of aquifers and surface water bodies that support local agriculture and ecosystems.
