To Combat Monsoon Flooding:

10 Vehicle-Mounted Mobile Pumps Deployed by BMC for Immediate Water Drainage

In a first-of-its-kind initiative this year, the Brihanmumbai Municipal Corporation (BMC) has deployed ten vehicle-mounted mobile dewatering pump units to tackle urban flooding in low-lying areas during the monsoon. These units aim to rapidly drain accumulated rainwater, especially in areas where fixed dewatering pumps fail due to various reasons.

Each vehicle is equipped with two high-capacity pumps, with each pump capable of draining up to 250 cubic meters of water per hour.

In recent years, significant shifts in rainfall patterns have been observed due to climate change. Specific areas of Mumbai have recorded extreme rainfall of 250 to 300 mm in a very short span. This year, Mumbai witnessed record-breaking pre-monsoon rainfall in May itself. Considering the city’s unique topography, the BMC undertakes annual flood-mitigation measures to ensure that rainwater is drained in minimal time and that citizens face minimal inconvenience.

As part of these flood management efforts, the BMC deploys 514 dewatering pumps across vulnerable zones every year. However, in the event of equipment failure, seamless and efficient backup systems must be available.

“All dewatering mechanisms, including backups, must operate at full capacity and without failure,” emphasized Additional Municipal Commissioner (Projects), Mr. Abhijit Bangar.

Accordingly, the Storm Water Drain (SWD) Department has decided to procure ten vehicle-mounted mobile pump units on lease for a four-year period from 2025 to 2028. These pumps will serve as immediate response systems in case of emergencies.

The deployment will include one vehicle per zonal Deputy Commissioner’s office (total 7), and one each at the offices of the Deputy Chief Engineers for SWD Operations & Maintenance, Eastern Suburbs, and Western Suburbs (total 3). Each vehicle will carry two pumps with a drainage capacity of 250 cubic meters per hour per unit.

This proactive move will ensure swift response during flood events and reduce reaction time significantly. The mobile pump units are expected to reach flood-prone locations on short notice.

“These vehicles must be manned around the clock in three shifts to ensure 24×7 operational readiness,” instructed Mr. Bangar. “Quick mobilization is critical to minimize waterlogging and safeguard public movement during the monsoon
