Even as the Bangalore Water Supply and Sewerage Board is yet to resume normal water supply in some areas after last week's crisis, Bangaloreans will have to face another dry day on Sunday.
The entire city will be affected as pumping from all the four stages of Cauvery had stopped for nearly six hours at Tataguni after the 220 KV line in this reservoir tripped.
Last week, the whole of Bangalore went without water for four days after a part of the raw water canal between Shiva Balancing Reservoir and Netkal Balancing Reservoir was breached. Board officials, who could not plug the breach, had to use the services of the Madras Engineering Group (MEG) and Centre and Karnataka Power Transmission Corporation Limited (KPCL) to take up the emergency repair.
A top BWSSB official told The Hindu the main transformer burst at Tataguni around 1 p.m. on Saturday. Although officials got it repaired, the main 220 KV power line tripped, disrupting power supply to the reservoir. Following this, pumping had to be stopped for nearly six hours, the official said.
“Although we restored the lines and resumed pumping from Cauvery 1st, 2nd and third stages by late evening, pumping from the fourth stage might take a little longer,” the official said.
This problem will affect water supply to the entire city on Sunday.
While the supply will not be stopped totally, the timings will be rescheduled and the duration of supply reduced.
Meanwhile, the BWSSB is planning to stop pumping from the Thippagondanahalli reservoir from the first week of May if the water level, which has plummeted to 16 feet, does not rise by then. The official said that only one of the two pumps of this reservoir was running and only 22 million litres of water a day (MLD) was being drawn from here.
Dependent on rain
“If there are no rains by then and the water level does not increase, we will have to stop drawing water from this source. This is likely to affect supply in the western parts of the city,” the official added.
