Safeguarding Mumbai from Monsoon Flooding with High-Capacity Storm Water Pumping Solutions
Mumbai, originally a cluster of seven islands, faces severe flooding challenges during the monsoon season due to its coastal geography, intense rainfall, and high tide conditions. With an average annual rainfall of 2,420 mm—and daily extremes reaching up to 400 mm—gravity-based drainage often fails when heavy rains coincide with high tides. This leads to large-scale inundation of low-lying areas, affecting homes, businesses, transportation networks, and critical infrastructure, resulting in significant economic losses and risks to human life.
To combat this recurring challenge, Wilo axial submersible pumps have been deployed across four major storm water pumping stations—Haji Ali, Britannia, Lovegrove, and Cleveland. Nearly thirty high-capacity pumps operate continuously during the monsoon season, protecting South Mumbai from flooding. Wilo India has played a key role in this project from the design stage through execution, ensuring reliable performance, operational efficiency, and long-term service support for these critical flood-mitigation systems.
The Wilo storm water pumping solution plays a critical role in protecting Mumbai—a city with one of the largest storm water drainage networks in India—from catastrophic monsoon flooding. By combining high-capacity axial submersible pumps with expert system design and comprehensive service support, Wilo ensures efficient removal of floodwater even under extreme rainfall and tidal conditions. This project stands as a benchmark for large-scale urban flood management and resilient coastal infrastructure in India.
Large-Scale Sewerage & Storm Water Pumping Systems
Kolkata Municipal Corporation (KMC) is responsible for the planning, development, and maintenance of the city’s civic infrastructure, including sewerage and drainage systems. Large parts of Kolkata operate on a combined sewerage network developed over more than a century, which faces increasing stress due to population growth, aging assets, and low-lying terrain prone to flooding and prolonged waterlogging.
Under the SD-32 project, a high-capacity combined sewerage and storm water pumping station has been constructed to manage both dry weather flow and storm water flow. The pumping systems are designed to operate continuously under demanding urban conditions, handling high flow rates, mixed sewage, and storm water during peak monsoon events. The installation supports effective flood mitigation, improved sewage conveyance, and enhanced reliability of the city’s drainage network.
Urban sewerage and drainage applications impose severe hydraulic and mechanical demands on pumping equipment due to continuous operation, high inflow variability, suspended solids, and extreme weather conditions.
