BMC Imposes 20% Water Cut for Mumbai Commercial Users as Lake Levels Drop to 10%
On June 16, 2026, the Brihanmumbai Municipal Corporation (BMC) imposed a 20 percent water cut for commercial and industrial users across Mumbai, alongside suspending temporary water connections for construction sites. The decision was prompted by a delayed monsoon, which caused the total water stock in the city's supplying lakes to deplete to a critical level of 10.35 percent.
The BMC confirmed that the ongoing 10 percent water cut applied to residential areas across Mumbai will continue to ensure the remaining stock lasts longer. The municipal body issued these directives in a circular on Tuesday, warning of strict penalties for anyone found wasting or misusing drinking water.
Under the new regulations, heavy industries and major organizations operating in the city must mandatorily transition to recycled or treated sewage water for their operational needs. These entities include the Western Railway, Central Railway, Rashtriya Chemicals and Fertilizers (RCF), Hindustan Petroleum Corporation Limited (HPCL), Bharat Petroleum Corporation Limited (BPCL), Maharashtra Industrial Development Corporation (MIDC), and the Indian Navy.
The civic body has also targeted construction activities to conserve resources. No new water connections for construction sites will be sanctioned, and all existing temporary connections for these sites are suspended immediately.
Additionally, water supply to swimming pools throughout the city has been temporarily disconnected. For aerated and packaged drinking water bottling plants, the BMC has slowed water supply to strictly meet only the drinking needs of the workers.
The circular also bans the use of drinkable water for washing vehicles, gardening, or cleaning roads. The BMC has urged citizens to use borewells or wells for these activities instead. Public toilet operators have also been instructed to maximize the use of tankers and borewell water.
Mumbai relies heavily on rainfall for its water supply, which is drawn from seven key lakes: Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vihar, and Tulsi.
