Cooum River's Clean Stretch Choked by Sewage

A pristine section of the Cooum River in Tiruvallur district is facing degradation due to untreated sewage discharge. Urbanization and inadequate sewage systems have led to raw sewage entering the river, jeopardizing freshwater storage in check dams and the river's health downstream. Residents are concerned about the declining quality of groundwater, which is a vital source for local communities and irrigation.

The situation is exacerbated by a dysfunctional sewage treatment plant, with raw sewage reportedly flowing through stormwater drains. Residents have submitted multiple petitions urging for effective sewage treatment before discharge and stricter monitoring to prevent groundwater contamination. The local municipality is working on pipeline extensions and new treatment facilities.

Authorities are implementing advanced treatment technologies and introducing bacteria-based chemicals to break down pollutants and improve wastewater quality. A new sewage treatment plant is nearing completion, and proposals for shutters at the Putlur check dam are under consideration to enhance water storage. The Water Resources Department is also monitoring treated sewage quality to ensure it meets permissible limits.
