The Brihanmumbai Municipal Corporation (BMC) has announced a temporary 5 per cent reduction in water supply across several parts of the city and eastern suburbs from April 20 to April 27, 2026, due to essential maintenance work on key water tunnels.
Maintenance work on major water tunnels
According to the BMC, the work will involve charging, flushing, chlorination, and dechlorination of Water Tunnel No. 1 (AMT-1) and Water Tunnel No. 2 (AMT-2), both of which play a crucial role in Mumbai’s water distribution network.
Water Tunnel No. 1 supplies water from Amar Mahal (Hegdewar Garden) to Wadala (Pratiksha Nagar) and further to Parel (Sadakant Dhavan Garden). Meanwhile, Water Tunnel No. 2 runs from Amar Mahal to the Trombay Low-Level and High-Level Reservoirs, ensuring continuous water supply to key areas.
The civic body stated that these maintenance operations are necessary to ensure the long-term efficiency and safety of the water supply system.
Areas to face water supply reduction
The BMC said the 5 per cent water cut will affect several wards in the eastern suburbs, including L (Kurla East), M East, M West, N, S, and T wards.
In addition, parts of south and central Mumbai under A, B, C, E, F North, and F South wards will also experience reduced water supply during the same period.
Citizens urged to cooperate
The BMC has appealed to residents in the affected areas to use water judiciously and cooperate with the administration during the maintenance period.
Officials emphasised that the reduction is temporary and aimed at improving the overall reliability of Mumbai’s water infrastructure.
BMC announces water cut in parts of south Mumbai on April 16-17
Earlier, on April 10, the BMC announced a temporary disruption in water supply in several parts of south Mumbai on April 16–17, stating that the supply will be affected for 18 hours as it plans to undertake essential work on a major water distribution line.
The water cut is scheduled from 10 am on Thursday, April 16, to 4 am on Friday, April 17, 2026, officials said.
The BMC will install two 1500 mm butterfly valves on the tunnel water pipeline at Haji Bunder Road in the F South Ward, near Sewri, they said.
According to the Mumbai civic body, the work is being carried out to improve and regulate water supply from the Bhardavada Hill Reservoir, Phosberry Hill Reservoir, and Golnaji Hill Reservoir.
An official statement said that due to the work, parts of the A, B, C, E, and F-South BMC wards will experience either complete water supply shutdown or low-pressure supply during the operation period.
The operation will impact several key areas, including residential zones, commercial pockets, hospitals, and government offices.
