Mumbai Reservoirs Report 22.26% Water Stock Amidst Seasonal Concerns

The Brihanmumbai Municipal Corporation (BMC) has disclosed that the combined water stock in Mumbai’s crucial reservoirs stands at 22.26% as of July 11, according to recent data.

This figure reflects the stored water across seven reservoirs vital for supplying drinking water to Mumbai, including Bhatsa, Upper Vaitarna, Middle Vaitarna, Tansa, Modak Sagar, Vihar, and Tulsi, situated across Mumbai, Thane, and Nashik districts. Comparatively, on the same day last year, the reservoirs held 26.43% of their useful water stock amounting to 3,82,540 million litres, while in 2022, the water levels were significantly higher at 40.32%, totaling 5,83,640 million litres.

Mumbai’s daily water requirement fluctuates between 4,000 to 4,500 million litres, emphasizing the critical need to manage and sustain the available water resources effectively. The total holding capacity of these lakes amounts to 14.47 lakh million litres. Current reservoir levels indicate Tansa at 45.57%, Modak Sagar at 37.73%, Middle Vaitarna at 22.15%, Tulsi Lake at 58.59%, and Vihar Lake at 40.96% of their respective capacities. Notably, Powai Lake, with a storage capacity of 545 crore litres, began overflowing recently, though the water is designated solely for industrial use and not suitable for drinking purposes.

From the gross usable content of Bhatsa, 5,75,700 million litres are allocated for Municipal Corporation of Greater Mumbai (MCGM) consumption. Additionally, the Maharashtra government has allocated 1,37,000 million litres from Bhatsa and 91,130 million litres from Upper Vaitarna dam for Mumbai’s water supply this season.
