Mumbai’s 10 per cent water cut will continue as the Brihanmumbai Municipal Corporation urges residents, housing societies, businesses and public institutions to conserve drinking water amid concerns over reservoir levels and a persistent gap between the city’s requirement and available supply.
The BMC said below-average rainfall in 2026, influenced by climate factors including El Nino and the Indian Ocean Dipole, has affected water availability in the seven lakes that supply Mumbai. The civic body has appealed to citizens to use water judiciously, prevent wastage and adopt conservation measures so that the available stock lasts longer.
Mumbai and its suburbs require around 4,664 million litres of water per day, while the average supply from available sources is approximately 4,100 million litres per day, according to the information released by the civic administration. The shortfall has added pressure to the city’s water management system as the BMC continues to assess future drinking-water requirements.
The 10 per cent Mumbai water cut was implemented from May 15, 2026, following directions from the Maharashtra government’s Water Resources Department. The reduction remains in force while the civic administration focuses on preserving the available reservoir stock and planning water availability up to August 31, 2027, in accordance with state government directions.
The BMC has asked residents not to leave taps running unnecessarily and to repair leaking taps and pipelines promptly. Housing societies, commercial establishments, industries, educational institutions and public organisations have been advised to use treated sewage water, wells, tubewells or borewells for activities that do not require potable water.
The civic guidelines say treated water from sewage treatment plants or borewell water should be used for construction work wherever drinking water is not necessary. Alternative sources should also be used for vehicle washing, gardening, road washing and cleaning surrounding areas. Organisations managing public toilets and washrooms have been asked to use non-potable water wherever possible, while drinking water must not be used to fill swimming pools.
The existing 20 per cent reduction in water supply to industrial and commercial establishments and sports clubs will also continue. The BMC’s Hydraulic Engineer Department has formed special teams to address water losses caused by leakage, prioritise leak prevention and respond to reported cases within stipulated timelines.
The civic administration has warned that appropriate action will be taken against misuse of water supplied by the BMC. It has asked Mumbaikars and institutional users to avoid using drinking water for non-essential purposes and maximise the use of alternative sources as the city manages its available stock.
