Mumbai Water Stock Crosses 40% Mark Amid Steady Monsoon Showers

Mumbai, June 30 – Mumbai’s water security received a substantial boost as the total water stock in the city’s seven key lakes crossed the 40 per cent mark, thanks to consistent monsoon showers over the past week. As per the latest figures released by the Brihanmumbai Municipal Corporation’s (BMC) Hydraulic Engineer’s Department at 6:00 am today, the city’s water stock stands at 5,82,175 million litres — 40.22 per cent of the required total storage capacity of 14.47 lakh million litres.

The cumulative rainfall recorded at the Bhandup Complex has reached 474 mm, with 2 mm received on Sunday alone. The sustained rainfall has led to a significant rise in water levels across all major lakes supplying drinking water to Mumbai.

Bhatsa Lake, the city’s largest water supplier, recorded 21 mm of rainfall on Sunday, bringing its cumulative monsoon total to 788 mm. It now holds 2,44,439 million litres, which is 34.08 per cent of its capacity.

Modak Sagar has shown robust improvement, storing 68,955 million litres, which is 53.48 per cent of its useful storage. The lake received 20 mm of rain in the last 24 hours. Similarly, Upper Vaitarna has reached 47.78 per cent capacity, following a 0.12-meter rise in water level.

Tansa and Middle Vaitarna lakes, located in Thane district, have also recorded encouraging figures. Tansa currently holds 61,707 million litres (42.53%), while Middle Vaitarna stands at 43.28 per cent.

The combined stock from Upper Vaitarna, Tansa, Modak Sagar, and Middle Vaitarna now totals 3,22,906 million litres — a significant step forward in ensuring the city’s short-term water security.

Within city limits, Tulsi and Vihar lakes recorded rainfall of 10 mm and 20 mm respectively. Tulsi now stands at 40.24 per cent of its capacity, while Vihar is at 42.21 per cent.

With lake levels now exceeding 40 per cent, civic officials are cautiously optimistic about the city’s immediate water availability. “The water situation is under control for the short term,” a BMC official stated, adding that continued rainfall through July is essential to avoid future water cuts.

The civic body continues to monitor lake levels closely and will adjust supply strategies based on further rainfall and usage patterns. Mumbai typically enters its peak monsoon phase in July, making the coming weeks critical in ensuring sufficient reserves for the post-monsoon months.
