Mumbai Water Stock Reaches 92%, 10% Cut Remains

Mumbai's water stock has increased to 92% as of August 15, 2026, with the city's seven lakes holding approximately 13.24 lakh million litres of water. This amount is sufficient to meet Mumbai's water requirements for around 323 days.

The water stock has risen from around 88% over the past three weeks, with several lakes overflowing due to recent rainfall. Tansa and Modak Sagar, two major water sources in Thane district, are among the lakes that have reached overflowing levels.

In addition to these lakes, the smaller reservoirs of Vehar and Tulsi in Mumbai are also overflowing. The combined water stock in the seven lakes is higher than the same period last year, when it stood at 12.95 lakh ML. However, it is lower than the 13.48 lakh ML recorded in 2024.

Despite the improvement in water stock, the Brihanmumbai Municipal Corporation (BMC) has decided to retain the 10% water cut imposed since May 15 as a precautionary measure. The city still needs around 14.47 lakh ML of water by October 1 to ensure a full year's supply.

The BMC's decision to retain the water cut is due to concerns over rainfall during the remaining monsoon months. The El Niño phenomenon is expected to influence rainfall activity in August and September, which could impact the city's water supply.

The water stock in Mumbai's lakes is closely monitored by the BMC, which provides updates on the city's water supply through its social media channels. The corporation has been working to ensure a steady water supply to the city's residents, while also taking measures to conserve water and prevent waste.

The 10% water cut imposed by the BMC is aimed at conserving water and ensuring that the city has sufficient supply throughout the year. The cut has been in place since May 15 and will continue until further notice.

In conclusion, while Mumbai's water stock has improved, the city still needs to be cautious about its water supply. The BMC's decision to retain the 10% water cut is a precautionary measure to ensure that the city has sufficient water throughout the year.

The improvement in water stock is a positive development for Mumbai, but the city must continue to conserve water and take measures to prevent waste. With the El Niño phenomenon expected to influence rainfall activity in the coming months, it is essential for the city to be prepared and take necessary measures to ensure a steady water supply.
