Delhi LG Orders Phased Revival of Sanjay Lake

The order seeks to fix treated-water supply failures blamed for May’s fish kill, rebuilding the lake's ecology and recreational use.

Overview

  • Lieutenant Governor Taranjit Singh Sandhu visited the site and directed the Delhi Development Authority to start a phased engineering and ecological revival of the 52-acre lake and its 165-acre protected forest.
  • He ordered the Delhi Jal Board to expedite repairs to the pipeline from the Dallupura sewage treatment plant to restore a steady supply of treated water that officials say failed in May and contributed to mass fish deaths.
  • On-ground remedial work is already under way, including continuous de-weeding, algae removal, repair of broken boundary walls, and embankment slope strengthening using geo-textile technology.
  • Planned technical measures for later phases include channelising stagnant flows, installing bioswales to boost groundwater recharge, carrying out bio-remediation, and fitting aerators and fountains; one agency has proposed Phase I completion by August 2026 and Phase II by May 2027 but those targets remain subject to implementation.
  • The LG also ordered a plantation of 5,000 native trees and asked for greater coordination with resident welfare associations and potential corporate support to secure long-term park management, public recreation, and improved local groundwater recharge.
