Faults in transformers at sub-stations to hit flow

City will get water in trickles today

The problem occurred due to faults in transformers at Tataguni and Somanahalli sub-stations on Saturday afternoon.

Instead of the regular supply of 900 million litres per day (MLD) of water to the City, only 700 MLD will be supplied on Sunday, said Chief Engineer (Maintenance),  Bangalore Water Supply and Sewerage Board (BWSSB), T Venkataraju. “No specific area will bear the brunt. The reduction in water supply will be spread uniformly across all areas of the City,” he said.

According to Narayan, the additional chief engineer (ACE), Cauvery, the 50 MVA transformer on the 220 KVA sub-station at Tataguni which supplies power for pumping water to the City sent out alarm signals at 12.45 pm indicating a fault.

Water from Cauvery passes through T K Halli, Harohalli and finally Tataguni before it reaches Bangalore. Venkatraju said the problem cropped up at Somanahalli sub-station, too.

“All the pumps which supply water to the City tripped and hence pumping of water from Tataguni to the City came to a standstill until 5 pm,” he said.

A BWSSB spokesman said the transformer developed snags due to earthing.
The transformer has been disconnected and was being repaired, he added. Power supply was later restored to the pumps through a 66KVA line and pumping of water resumed.
The pumps tripped again at 7 pm and the pumping would be restored later in the night, Venkataraju said.
