As a precautionary measure, Mumbai faces a 10% water cut amid dwindling levels in reservoirs, the Brihanmumbai Municipal Corporation (BMC) has warned of stringent action, including criminal cases, against citizens caught using electric pumps to illegally siphon off water from pipelines.

The civic body enforced a 10% water cut in the metropolis starting from Friday (May 15, 2026) as a precautionary measure amid falling water stock in lakes and forecasts of below-normal monsoon conditions linked to El Niño and Indian Ocean Dipole (IOD) patterns.

According to the BMC, the total usable water stock in the seven reservoirs supplying Mumbai stood at 3,40,399 million litres on May 11, which is 23.52% of the annual required stock of 14,47,363 million litres.

Additional Municipal Commissioner (Projects) Abhijit Bangar on Friday (May 15, 2026) directed civic officials to intensify action against illegal practices, and said repeat offenders would also face disconnection of water supply.

Mr. Bangar noted that inspections conducted by the civic administration have revealed instances of residents installing electric pumps directly on pipelines and tap connections to extract excess water, resulting in low-pressure supply in other areas.

“Such illegal practices put additional stress on the water distribution system and increase the risk of contamination entering pipelines,” he said. Officials were directed to seize unauthorised pumps, impose penalties and register criminal cases against violators.

Mr. Bangar also instructed engineers to undertake ward-wise micro-planning to ensure regular water supply with adequate pressure during water rationing. He directed officials to identify areas likely to face supply issues, including elevated and tail-end localities, and prepare action plans to minimise inconvenience to citizens.

Field-level engineers have been directed to remain at worksites, speak to residents and public representatives, and ensure complaints related to water supply are resolved promptly.

Mumbai’s primary water supply comes from Tulsi, Vihar, Bhatsa, Modak Sagar, Tansa, Upper Vaitarna, and Middle Vaitarna lakes located across Mumbai, Thane, and Nashik districts.
