BENGALURU: A massive effort to treat the sewage entering the Thippaggondanahalli reservoir (T G Halli) via Madavara Lake on Nice Road is yet to start operations, as the Karnataka State Pollution Control Board (KSCPB) has not released nearly `10 crore promised for it.
The reservoir, located 35 km from the city, was the main source of drinking water to the City decades ago. However, since November 2012, water from here was not used because it was found unfit for consumption.

T G Halli presently has water up to 41 feet out of its total capacity of 74 feet, said a top official in the Cauvery Division of BWSSB. “Sewage from Madavara Lake flows into Arkavathy River which supplies water to T K Halli along with Kumudavathi River. Due to shortage of rainfall, there has been no water supply this year,” the official said.
The Detailed Project Report for it was readied by the Bengaluru unit of an Israeli concern Ayala Water and Ecology and had been accepted by BWSSB for implementation.
When asked about it, KSPCB Chairman, Lakshman, told Express, “We have okayed the release of `9.8 crore for the project in our meeting early this month. We will release it shortly.”
Meanwhile, the last date for the tender called by BWSSB to finalise a consultant to prepare a DPR for restoration of T G Halli and Hessarghatta lakes is December 5.

The Yettinahole Drinking water project will provide 0.8  tmc ft of water to Hessarghatta and 1.7 tm cft to T G Halli after both these water bodies are rejuvenated, said Engineer-in-Chief Kemparamaiah. “After a consultant is appointed shortly for readying the DPR, it would take up to two months for the report to be submitted. Overall, it would take two years for the lakes to be restored fully. So by 2018, the City can look at receiving an additional 135 MLD to 140 MLD from T G Halli,” he said. Since October, BWSSB has been pumping between 1,335 MLD and 1,340 MLD of water to the City daily from the Thoraikadanahalli Reservoir. Water from T G Halli is looked at one of the major ways to supplement it in future.
