Rajesh B. Nair A sewage treatment plant is being planned on the southern side bund of Kanakaneri at Thattanchavady in Puducherry. PUDUCHERRY: The Kanakaneri, one of the oldest waterbodies in the town, is once again in the news. Environmental activists have come out against the government's decision to establish a sewage treatment plant on Kanakaneri under the Comprehensive Sewerage Scheme. They argue that setting up the plant would destroy the lake, which once served as the main source of irrigation for the town and its adjoining areas. During the last several years, encroachment on the waterbody remained unchecked and desilting operations were not carried out, which had led to the shrinking of Kanakaneri, president of Sembadugai Nanneeragam, Puducherry, K. Ramamoorthy told The Hindu.
