As the water stock in reservoirs drops down to 10 per cent, the BMC might have to take a call on water cuts in the next few days. Though there is a reserved stock of water for emergencies, the high water evaporation rate and the unpredictable monsoon left the authorities in a lurch.

The current water stock is lower compared to the same period last year. Though 10 per cent of water lasts over 28-30 days, the current rate of evaporation is very high. “The IMD predicted a good and early monsoon and we are keeping a close watch on it. Currently, it arrived in Andmans but may be delayed for a day or two in Kerala. The monsoon arrival dates for Mumbai haven’t been confirmed yet and we need at least two weeks of good rain to increase the water levels in lakes. The BMC will decide on the matter after taking all factors into consideration,” said a senior official from the BMC.
