GMDA to use drones to map illegal links, sewage discharge along Badshahpur drain
GMDA will deploy drone surveys along the 26-km Leg-3 Badshahpur drain to identify illegal pathways and sewage discharge points. The plan includes sealing unsafe access routes, removing encroachments, and coordinating with MCG on action against illegal discharges, with additional measures such as desilting, pump deployment, and diversions to relieve pressure on the stormwater network.
Why It Matters
The effort targets pollution control and public safety by limiting unauthorized sewage connections and improving drainage management in Gurugram.

4 Events
April 23, 2026 — GMDA drone survey plan and related measures
April 23, 2026
GMDA will deploy drone surveys to geo-tag polluted stretches and map unsafe access points along the 26 km Leg-3 Badshahpur drain from Ghata to Sector 99 via Vatika Chowk to seal unsafe pathways. Encroachments along a 6 km Dhankot–Basai stretch will be removed and grilles installed. An estimate for Leg-3 repair work will be prepared; aerial surveys will support mapping of polluted sections. The Municipal Corporation of Gurugram (MCG) will act against illegal sewage discharge points from commercial establishments in Sectors 66, 67 and 69; tenders have been floated for desilting work and for deploying pump sets to manage wastewater. An internal sewer line being laid to connect to the Dwarka Expressway is targeted to join the master sewer line by June 30, and MCG plans to divert wastewater from five under-tapped discharge points along the Gadauli culvert upstream (two near Behrampur and one each near Ullawas and Ghata) during this period.
