Mumbai’s water supply situation has come under closer scrutiny after the Brihanmumbai Municipal Corporation (BMC) asked officials to monitor rainfall over the lake catchment areas for the next two months.
Mumbai draws its potable water from seven lakes viz Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vehar and Tulsi, which together have a cumulative storage capacity of 14.47 lakh million litres. On Tuesday, the total stock in the these lakes touched 15% or 2.21 lakh of the total capacity. With each one percent of lake stock providing water for three days, the current stock can last the city for the next 45 days, reports The Indian Express.
During a recent review meeting, the BMC administration directed officials to keep a close watch on rainfall activity over the catchment areas that feed the city’s reservoirs. Civic officials said that while it was too early to announce further restrictions, the forecast of around 90% of average rainfall had raised concerns.
“While it is too early to take any steps, the recent forecast of 90% of the average rainfall is concerning as we have to ensure that Mumbai has sufficient water in its lakes till the next monsoon season, even if we do not receive adequate rainfall in the lakes,” a senior official privy to the developments told The Indian Express.
The city is currently facing a 10% water cut, which came into effect on May 15. Officials said the next two to three months would be crucial in determining whether Mumbai can avoid a deeper water supply challenge.
Civic officials also warned that inadequate rainfall, combined with intense heat later in the year, could worsen the situation. If the lakes fail to receive sufficient rain and Mumbai experiences severe heat in October, evaporation losses could increase, potentially creating a more serious situation during the summer of 2027.
