The M_sChennai Metropolitan Water Supply and Sewage Board New Perungudi 54 MLD STP Phase II 60 MLD is a wastewater treatment plant located in Chennai Corporation, Tamil Nadu, India. It serves a population of approximately 400,872, making it a large-scale facility within the Chennai metropolitan area. The plant is operational and plays a key role in managing the city's wastewater. The plant operates under India's Water (Prevention and Control of Pollution) Act, 1974, and the Environment Protection Act, 1986. For a facility of this scale, secondary treatment is typically required, and the plant likely meets standards set by the Tamil Nadu Pollution Control Board (TNPCB). The designed capacity is 1.00 MLD, indicating a significant infrastructure investment. The treated effluent is discharged into the local water system, which ultimately drains into the Bay of Bengal via the Adyar River or other coastal waterways. This discharge supports the region's aquatic ecosystems but also requires careful management to prevent pollution in the coastal environment. The plant's location within 50 km of the coast underscores its importance in protecting marine water quality.
Environmental context
The plant's treated wastewater flows into the Chennai coastal watershed, eventually reaching the Bay of Bengal via rivers such as the Adyar or Cooum. This coastal ecosystem supports diverse marine life and is a critical habitat for fish and migratory birds. Proper treatment is essential to prevent nutrient loading and contamination that could harm the sensitive coastal environment and affect local fisheries and tourism.
