Twin Ponds Revived: A Win for Groundwater and Biodiversity

The Pozhichalur Thangal, a vital waterbody near Pammal, has undergone a significant restoration, transforming from a neglected site marred by garbage dumping and sewage into a thriving ecosystem. The Environmentalist Foundation of India (EFI) spearheaded this initiative under the 'Blue-Green Chengalpattu' project, successfully removing over 11 tonnes of debris.

Restoration measures included comprehensive desilting and blocking sewage inlets, leading to a remarkable increase in the ponds' storage capacity to more than 8.6 crore litres. Invasive vegetation was cleared, and dual embankments were constructed. Five nesting islands for birds were also created using excavated silt.

Work on the seven-acre south pond commenced in September 2025, with the four-acre north pond completed by March of this year. Residents have welcomed the project, anticipating improved groundwater levels and a cleaner local environment, with hopes for enhanced well water availability after decades of decline.

Further enhancements include the development of a pedestrian pathway around the south pond, funded by MPLADS, with the State government expected to complete the remaining stretch and add amenities like lighting. Authorities are urged to prevent re-entry of sewage, ensuring the long-term health of the restored waterbodies.
