Delhi’s Rs 57,000-Crore Drainage Overhaul Targets 50% Flood Reduction, With Key Approvals Still Pending

Experts say success hinges on integrating sewerage and nature-based measures mandated by a recent court directive.

Overview

  • The Detailed Project Report has not received cabinet approval, and tendering will begin only after finance and other departmental clearances.
  • City planners have reorganised Delhi into three drainage basins and incorporated IMD analysis showing an 11% rise in rainfall intensity since 1994 with a similar increase projected by 2054.
  • Phase one prioritises critical flood spots including Minto Bridge, ITO, Mathura Road, Barapullah and key numbered drains for rehabilitation and capacity upgrades.
  • Specialists urge linking drains to wetlands, deploying SCADA and sensors, and folding sewerage redevelopment into the plan to prevent contamination and future conflicts.
  • Legacy policies that boxed or covered storm drains have hindered desilting and worsened waterlogging, with ongoing site-level fixes progressing slowly across agencies.
