As Mumbai battles the rising February heat, residents can take solace in an encouraging update—the city’s water reserves are in a better position than last year. Despite high demand, Mumbai’s overall water stock currently stands at 51.12%, which is 5% higher than the same period in 2024.
Last year, low water levels forced the Brihanmumbai Municipal Corporation (BMC) to impose a 10% water cut in June. However, this year’s improved stock may help delay or avoid such restrictions.
As of now, the seven lakes supplying water to Mumbai—Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vihar, and Tulsi—collectively hold 739,830 million liters, compared to 653,006 million liters (45.12%) at this time last year. Their total capacity stands at 1,447,363 million liters.
Currently, Mumbai receives 3,950 MLD (million liters per day) from these lakes, while actual demand remains higher at 4,500 MLD.
To address the growing water needs, the BMC is working on long-term solutions, including a desalination project at Manori and the construction of the Gargai dam in the Tansa sanctuary. The desalination project is expected to add 200 MLD within three years, with potential expansion to 400 MLD. Meanwhile, the Gargai dam could contribute an additional 440 MLD upon completion.
While the current water stock provides temporary relief, continued conservation efforts and infrastructural improvements will be crucial in ensuring Mumbai’s long-term water security.
