The Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) has taken up urgent work to repair sewer lines that have been damaged due to burst or leaking pipelines at various locations across the city.

This northeast monsoon, the board received 10,252 complaints related to overflowing sewage and mixing sewage with drinking water. Of these, most of the complaints are from Zones 6 (Thiru. Vi. Ka. Nagar), 10 (Kodambakkam) and 13 (Adyar). As many as 9,878 complaints were resolved.

Officials said that on days when it rained heavily, nearly 980 million liters of sewage was pumped a day, twice the normal amount of sewage collected in the network. As a result, in November, sewer lines were hit in 55 locations. Apart from repairing these, the CMWSSB has taken up the urgent work of repairing old pipelines that have burst.

Recently, major repairs were carried out on the Perambur Barracks Road to repair a damaged pipeline that caused the road to cave in. Similarly, work is underway to complete the repair work on the sewer line at Avvaiyar Street in Madhavaram zone, officials said. .

We received complaints about burst or leaking sewer pipes from 158 locations, and work is underway at the remaining 33 locations.

“We have increased the number of water samples taken from 200 sections for testing in our laboratory. About 3,300 water samples are tested daily,” the official said.

Apart from operating 323 sewage pumping stations on rainy days 24 hours a day, CMWSSB focuses on repairing damaged shafts. “In November, we received complaints of sewage overflowing in 2,313 manholes and most of the complaints were resolved,” the official said.

On some manhole covers that are placed unevenly in the city, officials said such manholes are identified as either buried in the road or protruding above the road surface to be leveled with the road.
