Putheri Lake in Chennai, initially planned as a crucial urban water buffer, is facing challenges despite a restoration initiative announced almost a year ago. The lake is grappling with issues such as continuous sewage inflow, encroachments leading to reduced boundaries, and accumulation of solid waste, casting doubts on the effectiveness of the restoration process.
Situated along the Radial Road in Chennai, Putheri Lake spans 10.45 acres and is part of a series of waterbodies in the area. Despite a restoration tender of Rs 3.4 crore by the Chennai Metropolitan Development Authority to enhance its storage capacity and ecological health, progress has been slow, mainly focusing on one section of the lake.
Efforts on the southern side have included limited desilting and removal of water hyacinth, but challenges persist. The primary inlet remains blocked by a concrete step, and multiple sewage entry points are still open, hindering the restoration progress. Additionally, the water overflow channel towards Keelkattalai Lake is clogged with plastic waste and sewage, impeding water flow.
The northern side of Putheri Lake faces more severe issues, receiving untreated sewage and overrun by water hyacinth. No restoration work has begun in this area, turning it into an open dumping ground. Encroachments around the lake have not been addressed adequately, limiting the restoration project’s effectiveness.
Environmental experts emphasize the need to halt sewage inflow and reclaim encroached land before implementing restoration measures to ensure substantial improvements. Officials mention that the approved plan encompasses both lake sides, with sewage inlets to be sealed after completing work on the southern part, followed by restoration on the northern side. Residents stress the urgency of coordinated action to prevent further deterioration of the lake and restore its vital functions in drainage, groundwater recharge, and public health protection.
