The Greater Chennai Corporation has yet to begin cleaning 19 of the 42 waterbodies it planned to tackle this year under various schemes. While work is underway on 20 of these water bodies, only three have been completed as of June 10.
An engineer of the Stormwater Drain (SWD) Department of the GCC, responsible for the cleaning, attributed the delay to the prolonged process of dewatering the ponds before cleaning and deepening them. Dewatering is done by draining the water from the waterbodies to the nearest SWD or canal, he said.
Jayshree Vencatesan, Managing Trustee at Care Earth Trust, said that dewatering is one effective methods of cleaning. However, she emphasised the importance of local bodies conducting surveys of water bodies and following the survey recommendations for dewatering. This approach would prevent excessive removal of earth and help water bodies retain rainwater, preventing them from becoming inundated during heavy showers, she added.
