New Drainage Design for Delhi: Masterplan to Tackle Flooding Issues

The Delhi government announced plans to finalize a comprehensive drainage masterplan to combat the city’s recurring waterlogging issues. With the current drainage system buckling under just 50 mm of rainfall, leading to severe flooding during monsoons, the initiative aims to transform the capital’s infrastructure. The plan, covering the Najafgarh, Barapullah, and Trans-Yamuna basins, is a critical step toward ensuring Delhi remains functional during heavy rains.

New Drainage Design for Delhi

Delhi’s topography has been divided into three key drainage basins—Najafgarh, Barapullah, and Trans-Yamuna—for targeted interventions. Each basin faces unique challenges, from clogged drains to inadequate outflow capacity, exacerbating urban flooding. The masterplan seeks to address these by redesigning the drainage network to handle higher rainfall volumes, reduce stagnation, and improve water flow to prevent disruptions in daily life and economic activity.

Delhi Govt Finalizes Drainage Plan

Consultants tasked with developing the masterplan are set to submit a draft report within the next 15 days, by July 28, 2025. This report will outline the proposed redesign of the drainage system, incorporating advanced engineering solutions and sustainable practices. Following the draft’s review, the Delhi government will present a finalized design, detailing infrastructure upgrades, timelines, and funding. This swift timeline reflects the urgency to mitigate flooding before the next monsoon season.

Masterplan to tackle Flooding Issues

Waterlogging has long plagued Delhi, causing traffic chaos, property damage, and public health risks. The new masterplan promises relief by enhancing drainage capacity to withstand heavier rainfall, ensuring safer roads and neighborhoods. Residents, especially in low-lying areas, are hopeful that the revamped system will prevent the annual ordeal of flooded streets and disrupted services.
