TG Halli Dam to resume water supply to Bengaluru

Bengaluru: The Thippagondanahalli reservoir has its water level risen up due to the rainfall will resume supplying water to Bengaluru.

TG Halli dam was built in 1933 at the confluence of rivers Arkavathi and Kumudavathi.

It was the first source of piped drinking water to Bengaluru, and was named Chamarajasagara.

BWSSB’s assistant engineer Ramakrishne Gowda S said the water level was just 42 feet four months ago.

“It has received record rainfall after about 15 years. The sluice gates built during the British era are opened when the level goes beyond 74.6 feet,” he added.

The decision to resume supply from the dam was taken after the quality of water in terms of TDS (total dissolved solids) was measured.

“The raw water shows less than 500 mg/litre of TDS, which is the standard level for supply. After treatment with alum and sodium hydrochloride, the water goes through sand distilling, the traditional method here,” said Chethan M S, chemist, TG Halli dam.
