There was only 10.6 feet of water in the dam on August 2. The dam can store up to 72 feet of water.

Last year, there was 33 feet of water in the dam on the same date.

According to data available with the Bangalore Water Supply and Sewerage Board (BWSSB), only six inches of water has flowed into the TG Halli dam till August 2 during this rainy season.

“The TG Halli catchment areas have not received adequate rain and normally a lot of water flows into the dam during August and September,” said BWSSB chairman PB Ramamurthy.

 At present, BWSSB is pumping 15 MLD of water to the city from TG Halli dam though it has the infrastructure to pump 125 MLD of water every day.

It is pumping nearly 900 MLD of water from all the four stages of Cauvery drinking water project, though it has a capacity to pump only 810 MLD. “The demand for water is increasing by the day and we are able to meet the demand due to the efficient distribution management of our officers,” said Ramamurthy. “It will be very difficult to meet the demand if TG Halli does not receive adequate water.”

BWSSB has already altered its method to treat water that is pumped from TG Halli reservoir as the turbidity level increases if the water level recedes beyond a level.
