The Brihanmumbai Municipal Corporation (BMC) on Tuesday announced a 20 per cent water supply cut across Mumbai and parts of the Western and Eastern suburbs following technical issues at the Pise Bandhara.
The civic body said urgent repairs are underway on the pneumatic gates installed at Pise Bandhara, along with irregularities in water release from Bhatasa Dam, leading to a rapid decline in water levels at the bandhara.
Due to the reduced water level, pumping stations could not be operated effectively, affecting water supply to the Bhandup Water Treatment Plant.
