Mumbai Water Stock Reaches 88.81%

Mumbai's drinking water reserves have continued to improve following fresh monsoon showers, with the combined stock in the seven reservoirs supplying water to the city rising to 88.81% of their total live storage capacity.

According to data released by the Brihanmumbai Municipal Corporation's (BMC) Hydraulic Engineer's Department, the increase follows rainfall recorded between 6 am on Monday, July 27, and 6 am on Tuesday, July 28, 2026.

The seven lakes, Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vihar, and Tulsi, now collectively hold 12,85,449 million litres (ML) of water against their total live storage capacity of 14,47,363 ML.

Among the reservoirs, Modak Sagar, Vihar, and Tulsi continue to remain at 100% useful live storage capacity. Tansa is at 99.02%, while Middle Vaitarna stands at 90.30%. Bhatsa, Mumbai's largest reservoir, has reached 87.36%, while Upper Vaitarna has climbed to 77.51% of its useful storage capacity.

The catchment areas received steady rainfall over the past 24 hours, with Upper Vaitarna recording 85 mm of rain, followed by Bhatsa with 72 mm, Modak Sagar with 57 mm, Tansa with 47 mm, Middle Vaitarna with 40 mm, Tulsi with 25 mm, and Vihar with 16 mm.

The Bhandup Complex, which houses Mumbai's Master Control Centre for water supply operations, recorded 15 mm of rainfall during the period, taking the season's cumulative rainfall at the complex to 2,261 mm.

Four reservoirs have already started overflowing this monsoon, with Vihar and Tulsi starting on July 7, Tansa on July 22, and Modak Sagar on July 23.

With reservoir levels now nearing 89% of total live storage capacity, Mumbai's water reserves remain in a comfortable position, providing reassurance over the city's drinking water supply as the monsoon season progresses.

The improvement in water reserves is a welcome relief for the city, which has been experiencing a relatively dry monsoon season so far. The BMC's efforts to manage the city's water supply have been successful, and the current reservoir levels are a testament to this.

As the monsoon season continues, it is essential for the city's residents to conserve water and use it judiciously. The BMC has been working to improve the city's water infrastructure, and the current reservoir levels are a positive sign for the city's water supply.

In conclusion, Mumbai's water reserves have improved significantly, and the city's residents can breathe a sigh of relief. The BMC's efforts to manage the city's water supply have been successful, and the current reservoir levels are a testament to this.
