Chennai Corporation will kick-start work on stormwater drains in the neighbourhoods along the East Coast Road in the southern zones of the city. The work will cover 52.5 km of stormwater drains at an estimated cost of ₹270 crore in areas, including Palavakkam, Neelankarai and Uthandi. The project was delayed for many years owing to paucity of funds.
Speaking at a press conference, Corporation Commissioner D. Karthikeyan said the government had given administrative sanction for the project. The Chennai Corporation is yet to get funding for other areas of Kovalam basin, such as Sholinganallur and Perungudi along Rajiv Gandhi Salai and the ecologically sensitive Pallikaranai Marshland.
Chennai Corporation will float bids shortly. The project has 27 outfalls, 127 roads and 318 nodes. Water stagnation in Sunrise Avenue, Maharashtra Bank on ECR, Bata Showroom on ECR, Sixth Avenue Modern Layout on ECR, Kottivakkam-Kuppam beach road junction, Kuppam Beach Road, Panaiyur Kuppam, Sea Cliff, Chinandimadam and Lakshmana Perumal Nagar will be reduced after the completion of the project.
In the first phase, around 405 km of stormwater drains have been constructed in zones of Ambattur, Valasaravakkam and Alandur in the basins of Adyar River and Cooum River. Work on stormwater drains in Kosasthalaiyar basin will be taken up after funding from Asian Development Bank, he said.
During the north east monsoon in 2015, the Chennai Corporation collected data on water stagnation in many locations. The civic body has developed new drains in 33 such locations. For example, work on stormwater drain along Habibullah Road in T.Nagar has been completed. Similarly, stormwater drains have been constructed along Tiruvottiyur High Road, Purasawalkam High Road, North Usman Road, Sardar Patel Road, Kumaraguru Avanue, Neelangarai and First Avenue Main Road in Vettuvankeni. However, the delay in getting funding from multilateral agencies has affected monsoon preparedness of the city.
Chennai Corporation has desilted 1498 km of drains at an estimated cost of ₹21 crore. Of the 210 waterbodies identified for restoration, 30 waterbodies have been restored using CSR funding. As many as 50 ponds are being restored using smart city funds. Ten ponds have been restored using capital fund of the Chennai Corporation. “We have resettled 13,923 families along waterways,” said Mr. Karthikeyan. The capacity of 30 canals has been increased by over three times by using amphibian vehicles and robotic excavators.
