Coimbatore Corporation has proposed to set up new sewage treatment plants at four lakes

With sewage continuing to pose a threat to waterbodies across the city, the Coimbatore Corporation has drawn up a fresh set of proposals to strengthen sewage treatment and restore lakes, with projects worth ₹31.17 crore planned across multiple zones.

According to the officials, sewage treatment plants (STPs) are currently in operation at eight of the nine lakes managed by the Corporation to prevent the inflow of untreated sewage. However, a recent assessment has identified the need for four additional STPs at Kurichi Lake, Singanallur Lake, Valankulam, and Periyakulam. The Corporation has estimated the cost of these new facilities at ₹20 crore.

Beyond sewage treatment, the civic body has proposed restoration works for several waterbodies in the West Zone. Subramaniya Nagar in Ward 38, Keerthi Nagar in Ward 39, and Madathur Kuttai in Ward 41 have been identified for desilting and related works, with a combined project cost of ₹4.35 crore. These works are proposed for the coming financial year.

In the South Zone, attention has turned to Kurichi Lake, where the existing barbed-wire fencing along the western and southern bunds has deteriorated. Citing public safety concerns, the Corporation has proposed the construction of a compound wall with fencing at a cost of ₹1.82 crore. Parallelly, infrastructure works are under way to channel surplus rainwater during the monsoon from the Sengulam into Sundakkamuthur Lake, aimed at improving water storage and reducing flood risk.

The North Zone proposals include the construction of retaining walls on both sides of the Palla Vaikkal in Ward 12, from Kandhasamy Nagar to Vayal Thottam, covering a length of about 600 metres. The project has been estimated at ₹3 crore.

In addition, the Corporation has planned works to strengthen lake bunds and create green cover along the waterbodies. Officials said the State government funding would be sought for the projects.
