BENGALURU: The recent Supreme Court directive asking Karnataka to release Cauvery water to Tamil Nadu may not have an immediate impact on Bengaluru's water supply.Kemparamaiah, engineer-in-chief, Bengaluru Water Supply and Sewerage Board BWSSB ) told TOI that even after releasing water to the neighbouring state for 10 days, they can meet Bengaluru's drinking water needs till December 2016. "However, if it doesn't rain enough in the next few months, we may find ourselves staring at a water crisis from January. We hope the city receives good rain during October and November so that a problem doesn't arise," he added.BWSSB is allotted 19 thousand million cubic feet of Cauvery water every year, of which 7tmcft has already been utilized since the beginning of monsoon. Though 12tmcft is needed to meet the city's requirements till the beginning of monsoon next year, it may not be available with the state government complying with the SC order.A senior BWSSB official said, "On an average, the city needs 1.5tmcft of Cauvery water every month to meet the daily supply of 1,400 MLD. We hope the Cauvery basin gets good spells of rain till December. Otherwise, we have to start water rationing from November. If it doesn't rain in the next two months, Bengaluru will face one of the worst drinking water crises in the recent past," she added.BWSSB has 9.13 lakh customers with water connections, including both domestic and non-domestic. Though the present infrastructure is equipped to supply 1,500 MLD of water, the pipeline network is yet to reach many peripheral areas.
