Work is in progress along a 5.3 km stretch, aiming to mitigate pollution

Some stretches of Adyar river now sport a cleaner look as the Water Resources Department (WRD) has started a desilting exercise. Sources at the WRD said the work is in progress along a 5.3 km stretch of Adyar river under the eco-restoration project, which aims to mitigate pollution and improve the waterway.

About 30 earth-movers are engaged in desilting the river and strengthening the river bank. The department has received Coastal Regulation Zone (CRZ) clearance for the stretch between Thiru Vi Ka bridge and Saidapet. The department is now awaiting CRZ clearance to take up similar work along 1.5 km stretch between the Adyar river mouth and Thiru.Vi.Ka. bridge.

Officials said the silt removed from the river bed would be conveyed to low-level areas within a radius of 16 km, including Perundudi and Kodungaiyur. Better quality soil from nearby areas, particularly localities where eviction has taken place, would be used to form bunds. Eviction drives are pending in localities such as Suriya Nagar and Kesavaperumalpuram.

The desilting work will continue for six months. Building of flood protection walls in vulnerable portions is also part of the project.

The project has been taken up along with the Chennai Rivers Restoration Trust, under which the 20-km portion of the waterway between the Adyar river mouth and Tiruneermalai is proposed to be improved

Meanwhile residents’ associations have questioned the wisdom of taking up desilting work after the the north-east monsoon has set in. If there are heavy rains, it is likely to undo the work undertaken by the WRD, washing out the accumulated earth back into the river.
