A larger monsoon preparedness plan has been drawn up by the Brihanmumbai Municipal Corporation as a rise in flood-prone locations has been recorded across Mumbai over the past year. In response, 547 dewatering pumps are set to be deployed across the city this monsoon, and a stronger anti-flooding mechanism is being put in place before the rains arrive. A cost of Rs 144 crore has been estimated for the exercise, and the western suburbs have been assigned the highest number of pumps under the new plan.
The expansion has been seen as a direct response to changing ground conditions in the city. More low-lying and waterlogging-prone pockets have been identified, and monsoon management is being intensified accordingly. Of the total pumps planned, 223 are to be installed in the western suburbs, 178 in the eastern suburbs and 146 in the island city. The move represents a clear increase from last year, when 510 pumps had been deployed, and from 2024, when the number stood at 482.
The civic body’s latest decision has also been influenced by last year’s difficult monsoon experience. The earlier pump deployment had been found inadequate during the extreme rainfall of May 26, 2025, when Mumbai experienced its earliest monsoon onset in more than 75 years. That event had exposed vulnerabilities in the city’s flood-response system, and a broader deployment now appears to have been adopted as a corrective measure.
A tender has already been floated by the BMC for contractors to operate and maintain the pumps during the monsoon. These pumps are typically installed in flood-sensitive areas so that rainwater can be removed quickly and discharged into nearby drains. This year, the contract period has been planned for two years, suggesting that the issue is being treated not only as a seasonal requirement but also as a continuing urban challenge.
The rise in flood-prone locations has been linked by senior officials to growing infrastructure activity across Mumbai. It has been stated that demands from ward-level officials have increased because works related to Metro construction, roads and bridges have led to more vulnerable spots emerging in several parts of the city. In that sense, urban development itself has been identified as one of the factors contributing to temporary flooding risks.
Municipal data has shown that 498 flooding spots have been identified this year, against 453 in the previous year, reflecting an increase of about 10 percent. Out of these, 391 locations have already been addressed. Another 52 are expected to be remedied within the next two months before the onset of the monsoon. For the remaining 55 locations, plans have been prepared, while 26 of them are to be handled in coordination with external agencies such as the railways, Metro authorities, the traffic department and MMRDA.
Overall, a wider and more structured flood-control approach has been adopted by the BMC this year. With more pumps, higher spending and longer contractor engagement, the city’s monsoon strategy is being strengthened in anticipation of another challenging rainy season.
