The Delhi government is set to overhaul 300 kilometers of the city’s drainage network starting April 1, 2026. This project is part of a massive ₹57,362.85 crore Master Plan designed to address the needs of a population that has grown to 2.75 crore. The Public Works Department (PWD) aims to reduce monsoon waterlogging incidents by 50% over the next three years by prioritizing chronic hotspots.
What are the key features of the new drainage plan?
The redevelopment follows a two-phase rollout over five years to modernize infrastructure that has remained largely unchanged since 1976, when the population was only 60 lakh. The new system is being built based on scientific assessments of natural slopes and depressions rather than the outdated designs of the past.
- Phase 1: Focuses on the next three years to fix over 160 chronic waterlogging hotspots.
- Phase 2: Covers years 3 to 5, focusing on drainage in colonies that currently lack proper infrastructure.
- Financial Support: The Delhi government has sought assistance from the World Bank and received ₹105 crore from the Central Government under the SASCI scheme.
- Technical Guidance: Experts from IIT Delhi and IIT Roorkee provided the technical blueprint for the major drainage basins like Najafgarh and Barapullah.
Which areas and technologies are being prioritized?
The PWD has already floated tenders for major works in Azadpur, Mehrauli-Badarpur (MB) Road, Nangloi, and Kanjhawala. To minimize public inconvenience, the department is adopting modern construction methods that do not require digging up entire roads. For instance, trenchless jack pushing technology is being used near Maharani Bagh to keep the Ring Road traffic moving smoothly.
| Project Location | Status/Update |
|---|---|
| Model Town 2 and 3 | Work started with ₹48.13 crore budget |
| Rohtak Road (NH-10) | Targeted completion by March 2026 |
| Kirari-Rithala Drain | Completion expected this month |
| Maharani Bagh | Use of trenchless technology for pipelines |
Officials confirmed that budget requirements for the 300 km revamp were finalized on March 3, 2026. The shift in strategy focuses on creating connected stretches instead of fixing isolated patches. This approach ensures that rainwater flows systematically into the major basins, preventing the standard overflow that leads to citywide traffic jams during the monsoon season.
