George tells officials to rejuvenate Ulsoor lake

Bengaluru Development Minister K J George has said that the construction work of mini sewage treatment plant (STP) at Ulsoor lake would begin soon.

After inspecting various works taken up to rejuvenate Ulsoor lake on Wednesday, the minister said, “Karnataka State Pollution Control Board (KSPCB) will fund Rs 4 crore for the construction of the mini STP at Ulsoor lake. The STP once functional will treat 2 million litres of waste water per day (MLD). The civil works will begin this month.”

George, accompanied by Infrastructure Development Minister Roshan Baig, BBMP Commissioner Manjunath Prasad and a host of officials, reviewed various other works taken up to make Ulsoor lake sewage-free. 

The minister directed Bengaluru Water Supply and Sewerage Board (BWSSB) to ensure sewage does not enter the lake. A BWSSB official told the minister that about 11 MLD of sewage enters the lake from the surroundings of Jeevanahalli through two inlets. Although, the flow of sewage has been diverted to a STP in Koramangala and Challagatta Valley, dirt water enters the lake during the monsoon. The official mentioned that many residents were letting sewage into the stormwater drains. 

BBMP Commissioner Manjunath Prasad has said that the Prestige Group has come forward to keep the lake clean.

Lake oxidation  George mentioned that a private firm (Eco Genentech) has been tasked to oxidise Ulsoor lake, which made headlines for a fishkill. “The BWSSB officials will test the water quality before and after the oxidation process. If the firm is able to purify the lake, we will implement it in all the lake,” he said.

“The oxidation would increase the DO level to desirable levels in the lake and bring down BOD and COD levels. It will eradicate the presence of blue green algae. Besides, the microbial population will reduce, which will bring down the foul odour,” the firm stated in a press release.
