The rainfall in September is key to water cuts in Mumbai. Only 30 per cent of the average rainfall was recorded in August. Due to this, there has been no expected increase in water stock in the seven lakes. If the water stock is not 100 per cent by the end of September, there is a possibility BMC will impose a water cut through the year.

On average there is rainfall of 400 mm to 500 mm in the lakes area in August. This year, in August just 100 mm to 150 mm of rain has been recorded, BMC’s Hydraulic Engineer Purushottam Malvade told the media on an official visit to the lakes. Till Saturday morning, there was 90 per cent stock in the lakes. “If by October 1, 100 per cent stock accumulates, the water supply will be smooth till June 15. If not, we will need to think about water cuts. We are hoping for a good wet spell as per the forecast,” Malvade added.
