Under the project, 610 industrial units in Guindy Estate and 398 houses in nearby localities of Labour Colony, Nagi Reddy Garden and Arulayamman Pettai have been given drainage connections by laying 18 km sewer lines. To facilitate pumping sewage to the treatment plant in Nesapakkam, two pumping stations have been built. While the main pumping station on Reddy Street close to the Estate has a capacity of 13.88 million litres per day (MLD), the Lift Station in the south phase has a capacity of 4.30 MLD.

After inaugurating the new facility, Stalin told reporters that with the launch of the facility, the seven outfalls that let sewage into the Adyar River would stop immediately, preventing pollution. “The sewage from Labour Colony, Nagi Reddy Garden and other areas will now go the treatment plant.” On the delay in the execution of the plan, Executive Engineer, Metro Water D Yuvaraj told Express that officials had to overcome plenty of problems. “One major trouble was the high water table and the entire area lay close to the Adyar River,” he said adding the region had buried networks of storm water and disused sewer lines that were laid many decades ago.

An IDS was prepared by SIDCO that maintains the industrial estate, to improve amenities and the task of laying sewer network was given to Metro Water. While the Guindy Estate Manufacturers Association pitched in with Rs 257.50 lakh for the sewer scheme, Metro Water’s fund component was Rs 477.50 lakh.
