Overview
- The Brihanmumbai Municipal Corporation reported on June 22 that the seven reservoirs supplying Mumbai held about 8.34% of usable storage, roughly 120,712 million litres of a 1,447,363 million litre capacity.
- Since the delayed monsoon reached Mumbai on June 23–24, intense local downpours have produced extreme short‑duration totals at automatic stations, flooding low‑lying areas and forcing the temporary closure of the Andheri underpass and some targeted rail services.
- Despite heavy local rain, reservoir levels have not seen a material rise and BMC officials say the city still faces a 500–600 MLD shortfall versus nominal demand, so they are running emergency demand measures including cloud seeding, flow meters at tanker points and squads against unauthorised use.
- Civic teams are reviving wells for non‑potable uses, prioritising tanker allocation to tail‑end areas and deploying pumps to dewater flooded subways while suburban rail and BEST buses largely continue to run with some localized suspensions.
- The BMC plans to add about 840 MLD by 2030 through projects such as the Gargai dam and Manori desalination plant but those schemes require clearances, soil tests and multi‑year construction so they will not ease this season’s shortfall.
