Overview
- The Expenditure Finance Committee approved a 4.48–4.5 km trunk drain along the Mundka–Kirari railway corridor as the first major project of the Drainage Master Plan.
- Northern Railway has granted land permission and a tripartite MoU is in place with the I&FC Department, MCD, DDA and PWD.
- The new trunk line is designed to carry about 760 cusecs, paired with a revamped DDA drain of roughly 433 cusecs to handle an estimated 1,193 cusecs from the Kirari catchment.
- Officials note the existing KSN drain carries only about 88 cusecs, a shortfall that contributes to severe monsoon waterlogging in the bowl-shaped, low-lying basin.
- More than 70 unauthorised colonies and nearby areas across Kirari, Nangloi Jaat, Bawana and Mundka are expected to benefit, though the secondary DDA drain faces delays due to pending tree-cutting permissions.
