Mumbai's seven drinking water reservoirs have crossed 77% of their total capacity after another day of heavy monsoon rainfall, with three lakes now overflowing and more rain forecast over the next 48 hours.
The city's seven lakes, which supply drinking water to Mumbai, collectively held 11,23,443 million litres against 14.47 lakh million litres capacity. In the last 24 hours, there has been a 7.88% increase in the reservoir stock.
Among them, three lakes - Vihar, Tulsi, Modak Sagar - have reached their full capacity and continue to overflow. Tansa, which reached its full capacity on July 22, currently stores 98.77% capacity. Bhatsa, the city's largest source of drinking water, currently stands at 73.51% of its capacity. Middle Vaitarna is also at 75.14%. Upper Vaitarna has reached 62.97% of its storage capacity.
The seven reservoirs - Bhatsa, Modak Sagar, Upper Vaitarna, Middle Vaitarna, Tansa, Vihar and Tulsi - are spread across Mumbai, Thane, Palghar and Nashik districts and depend largely on the southwest monsoon for replenishment.
