CHENNAI: Persistent sewage stagnation in four major subways of south Chennai has emerged as a serious concern, causing daily inconvenience and safety risks for motorists, especially two-wheeler riders, even in the absence of rainfall.
Subways serve as key connectivity routes in the city, with 22 such facilities currently functioning under the control of the Greater Chennai Corporation. Although advanced surveillance systems with modern cameras have been installed to monitor rainwater accumulation during the monsoon, recurring sewage stagnation during dry periods has now become a routine problem in several locations.
In particular, the Aranganathan, Pavalavannar, Madley Road and Duraisamy subways in south Chennai have witnessed continuous accumulation of sewage water over the past few days. The situation has created difficulties for commuters who depend on these routes daily, with two-wheeler riders facing the brunt of the problem.
As vehicles move through the stagnant water, sewage splashes onto riders, causing discomfort and raising health concerns. The prolonged presence of sewage has also made the concrete surfaces inside the subways slippery, significantly increasing the risk of skidding and accidents, especially for two wheelers.
Karthikeyan, a resident of T Nagar, who frequently uses these subways, pointed out, “Water stagnation in the rainy season was understandable, but its persistence during dry weather is unacceptable. Sewage water splashes on us every time a car or bus passes through. The authorities must take immediate action.”
When contacted, Deputy Mayor Magesh Kumaar said the stagnation at the Pavalavannar subway was not due to sewage but due to a leak in a Metro Water pipeline supplying water to the Railways. “I have instructed officials to take necessary action to address the leakage,” he told DT Next. “The issues in the remaining three subways can be resolved through minor maintenance works. Appropriate steps will be taken, and the problem will be addressed in the coming weeks.”
