The seven lakes that supply drinking water to Mumbai now hold only 10.3 percent of their total storage capacity, signaling an alarming depletion of reserves. In response, the Municipal Corporation of Greater Mumbai (BMC) has implemented stringent emergency measures to manage the rapidly deteriorating situation.
The BMC announced the immediate suspension of water supply to construction sites and swimming pools. In addition, a 20 percent reduction in water supply has been enforced across sports clubs, industrial units, factories, and commercial establishments. These directives came into effect on Wednesday and are now strictly operational across the city.
Authorities have issued a strong warning that any misuse or wastage of municipal drinking water will result in strict legal action under applicable regulations. The administration has emphasized zero tolerance toward violations amid the ongoing crisis.
The measures have been introduced following directives from the Maharashtra Water Resources Department. Acting on these instructions, the Hydraulic Engineer Department of the civic body has issued a detailed circular outlining mandatory compliance guidelines for all concerned entities.
At present, Mumbai requires approximately 4,664 million liters of water per day, while the actual supply has dropped to around 4,100 million liters per day from all available sources. This widening gap between demand and supply has further intensified the strain on the city’s water distribution system.
Earlier, the civic body had already implemented a 10 percent water cut beginning May 15. However, the prolonged delay in monsoon onset has forced authorities to extend and intensify water rationing measures to ensure sustainability of available reserves.
Under the new regulations, organizations managing public sanitation facilities have been directed to minimize the use of potable water and instead rely on tanker-supplied water or groundwater sources. Activities such as vehicle washing, gardening, and street cleaning are now strictly restricted to non-potable sources such as wells and borewells.
Major public and industrial institutions, including Central Railway, Western Railway, the Indian Navy, Hindustan Petroleum Corporation Limited, and Bharat Petroleum Corporation Limited, have also been instructed to significantly increase their use of treated wastewater. They are required to utilize recycled water supplied from facilities such as the Colaba sewage treatment plant and other treatment installations across the city.
The unfolding situation highlights the growing vulnerability of urban water systems to climatic variability and underscores the urgent need for sustainable water management in Mumbai.
