Mumbai’s drinking water reserves, drawn from seven reservoirs, rise as heavy monsoon rainfall continues over the city and surrounding catchment areas. BMC data cited by multiple outlets show that the combined useful live storage in the seven lakes increases to about halfway of total capacity, crossing the 50% mark on July 18. One report says the seven lakes hold 7,34,891 million litres (ML), or 50.77% of total capacity, after a 0.98% increase over the previous 24 hours. Another outlet reports that by July 12 the total useful live storage is 721,354 ML, or 49.84% of capacity, placing reserves close to 50%. Earlier in the monsoon period, reservoirs were much lower—around 41% on July 8–9—before rainfall led to faster gains over the following days. Several lakes reach higher levels at different times, with Vihar and Tulsi repeatedly reported as at or near full storage during peak wet periods. The BMC continues to track reservoir levels and rainfall patterns, while an ongoing supply management approach (including water cuts earlier) has been described as tied to whether reservoirs overflow and whether rainfall intensity sustains.

- Mumbai’s seven reservoirs supplying drinking water collectively reach around half of total useful live storage (50.77% reported as of July 18).
- BMC/Hydraulic Engineer’s Department figures show the reserves increase over short periods during heavy monsoon rainfall (e.g., a 0.98% rise in 24 hours reported on July 18).
- By July 12, combined useful live storage is reported at 49.84% (721,354 ML).
- During earlier days, storage is reported around the low-40% range (e.g., 41.36% on July 8–9) before rising with sustained rainfall.
- Vihar and Tulsi are repeatedly reported as reaching full or near-full useful live storage during the wet spells, while other lakes rise more variably.

1 month agoMumbai: Despite four of the seven lakes supplying water to Mumbai overflowing and the combined lake stock reaching 77 percent of capacity, the BMC has decided to continue the 10 percent water cut imposed on May 15, citing concerns over a possible El Niño-induced rainfall deficit in August and September.Stock Rose 16% in Two Days; Modak Sagar, Tansa, Vehar, and Tulsi FullAs of July 24, the seven lakes together hold 11.23 lakh million litres (ML) of water, enough to meet the city's needs for 274 days. Following heavy rainfall in Thane district, where most of the lakes are located, the water stock rose by nearly 16 percent between 6 am on July 22 and 6 am on July 24. Modak Sagar, Tansa, Vehar and Tulsi lakes have already reached full capacity.Maharashtra Govt Introduces Five-Star Rating System For 623 Public Hospitals To Boost Quality And TransparencyHowever, with the weather bureau forecasting low rainfall in August and September due to the expected El Niño effect, the BMC is adopting a cautious approach. "The El Niño effect is likely to persist until next year. The state irrigation department has instructed all civic bodies to plan water availability till August 31, 2027. We will review the situation once all seven lakes are full, likely by September, before taking a decision on withdrawing the water cut," a senior civic official said.Among the remaining lakes, Bhatsa is at 77 percent, Middle Vaitarna at 75 percent, and Upper Vaitarna at 62 percent of their capacities. Mumbai requires 14.47 lakh ML in its seven lakes by October 1 to ensure an uninterrupted year-round supply. The BMC currently supplies 4,100 MLD of water against a daily demand of 4,600 ML.
