Chennai Canals Choked: Six Months Later, Toxic Waste Flows

Six months after a report on toxic waste and sewage in Chennai's Kodungaiyur canals prompted suo motu action by the National Green Tribunal (NGT), concrete improvements are notably absent. Untreated sewage continues to be discharged into stormwater drains, ultimately polluting the Kodungaiyur North and South canals. This ongoing pollution has turned stretches of the canal into a significant health hazard for local residents.

The Tamil Nadu Pollution Control Board had previously inspected the area and confirmed illegal domestic sewage discharge into drains connected to the canal network. Following these findings, the board issued directives to the Greater Chennai Corporation and Metrowater officials to cease sewage discharge and ensure complete wastewater collection for treatment. However, residents report that little has changed on the ground.

Locals describe a persistent foul odor, a surge in mosquito populations, and overflowing drains during rains, significantly affecting their quality of life. Concerns are particularly high for children and the elderly. Despite occasional official visits, residents feel there has been no permanent solution implemented to address the continuous illegal sewage discharge, with some even reporting discharge from nearby industrial units.
