The Karperayan stream, originating from the Marudhamalai forest and feeding Krishnampathi Lake, has become a dumping ground for solid waste in recent months. While the stream remains dry for most of the year, during monsoon runoff it serves as the lake’s principal conduit, passing through neighborhoods such as Vadavalli, Linganoor, and Seeranaickenpalayam.

Environmental Concerns and Local Impact

Environmental activist K. Mohanraj highlighted that Krishnampathi Lake has two feeder channels—Koilmedu and the larger Karperayan. However, the Karperayan channel now carries primarily sewage and discarded materials rather than natural flow, owing to households and small businesses indiscriminately dumping waste, including plastic bottles and cough‑syrup containers.

Public Health Implications

R. Santhakumar of the NGO Aniver Amaippu reported large piles of plastic near the inlet point, especially close to the Government Law College. The blockage has caused water stagnation, creating ideal breeding grounds for mosquitoes and heightening the risk of dengue, malaria, and other water‑borne diseases for residents.

Municipal Response

Coimbatore Corporation officials confirmed that a complaint from Ward 75 (Netaji Main Road, S.N. Palayam) triggered an inspection on Monday. The individual responsible for the dumping was identified, fined ₹10,000, and warned against future violations. Authorities pledged intensified monitoring and stricter penalties for repeat offenders.

Looking Ahead

Experts argue that punitive measures alone will not solve the problem; a comprehensive approach—public awareness campaigns, robust waste‑management infrastructure, and community‑driven clean‑up drives—is essential. Without such interventions, Coimbatore’s water bodies risk descending into a chronic environmental crisis that could undermine the city’s livability and health standards.
