Mumbai’s water stock will sustain the city until September 5, 2027, if the 10% water cut is extended and the approved reserve storage in Upper Vaitarna and Bhatsa – dams that provide the major share of water to the city – is maintained, reported the water-supply planning data prepared by the Brihanmumbai Municipal Corporation (BMC) . It was presented by Abhijit Bangar, additional municipal commissioner (projects), at the civic standing committee on Thursday.
the situation is worrisome in other parts of the Mumbai Metropolitan Region (MMR) as they largely rely on the state irrigation department’s dams While Mumbai has water stock in its reservoirs. On the other hand, with the monsoon season officially ending on September 30, 2026, and 75.25% stock available in the state’s irrigation reservoirs, authorities have decided to regulate supply to farmlands until the onset of the monsoon in 2027, so that water is prioritised for drinking purposes until August 31, 2027, said an officer from the irrigation department.
Navi Mumbai’s Morbe dam has 74% stock, which is used by the Navi Mumbai Municipal Corporation (NMMC) to provide 498 MLD in its area. The civic body’s 10% water cut was revoked after September. Kalyan-Dombivli Municipal Corporation (KDMC) which gets 425 MLD water supply has communicated with the state government seeking additional quota, arguing that it has not been revised since 2018 despite the increase in population. Hence, we have demanded that the sanctioned quota be increased by 180 MLD,” said an official from the water supply department.
However, with limited stock in the dam now, NMMC has issued an advisory to citizens to save and use water conservatively. “As of now we have only issued an advisory to save water. “While there are no water cuts by KDMC, areas governed by it along the borders are facing shortage.
But we are waiting for the state government’s decision on possible future cuts,” said an official from NMMC.
