Eco-friendly, new-age stormwater drains network planned along ECR

The ECR is not only a popular road connecting Chennai with Mahabalipuram and Puducherry but a hub of many activities in itself. Now ECR will have an eco-friendly drain network. A combination of new-age drains, a cutting-edge rainwater harvesting system, artificial wetlands, sponge parks, and a series of recharge wells ideal for sandy soil will help prevent rainwater from being let into the sea.

Since many outfall locations of the conventional drains are breeding spots of Olive Ridley turtles, the civic body has junked the concrete drain project in Kottivakkam, Palavakkam, Neelankarai, Injambakkam, and the experts have started preparing a project report for eco-friendly drains.

As per the plan, the eco-blocks will have infiltration tanks that will allow rainwater to flow and collect in artificial ponds. Tree plantations and other vegetation beds will be used in locations where there is minimal or no water stagnation. Artificial wetlands will also be set up in areas of heavy inundation. New-age sponge parks that include an urban park space with tanks, greenery, and water beds to soak up rainwater will also be set up. All the road run-off will be stored there for a period of time which help in reducing water stagnation along the stretch.

Chennai gets most of its annual rainfall from mid–October to mid–December. Over the years, the city has depended on the annual rains in monsoon to replenish water reservoirs. As per government records, more than 8 lakh structures have rainwater harvesting facilities. Experts feel that in addition to individual structures at homes, initiatives like the upcoming facilities in ECR will ensure that public areas have harvesting systems.

There is an urgent need to stop the precious rainwater from stagnating on the roads and running off into the sea. The state-of-the-art #AquaStar rainwater harvesting systems assist residents to conserve water & prevent water from stagnating on the streets. Explore more at
