Water supply to several areas, especially in the east and northern parts of the city, was hit on Tuesday following Bangalore Water Supply and Sewerage Board (BWSSB)'s shifting of lines to provide link from 66kv to 220 kv at Tataguni Pumping Station. Residents of areas that are fed by Cauvery I, II, III Stages, whose supply was scheduled on Tuesday, had to go without water. Work on providing the link commenced at 10.30 a.m. and was completed by evening.

Although pumping was restored by 6.30 p.m. on Tuesday, areas whose supply is scheduled on Wednesday are also likely to be affected. This is because of the ground-level reservoirs will take some time to fill up in the areas that are fed by Cauvery I, II and III Stages, a top official said.

Of the 900 million litres of water per day (MLD) that is pumped to the city through four stages of the Cauvery, only 370 MLD was pumped on Tuesday. The BWSSB had announced two days ago that supply would be hit. This work was essential to prevent frequent tripping of power at Tataguni Pumping Station, the official added.
