"We have decided to conduct a study wherein the executive engineers from GHMC will determine what kind of water is being discharged in the lake -storm water or sewage water -and the spots from where it is entering the lake. We will be inspecting all the water connections that lead to the lake," said Harichandana, commissioner of West zone, GHMC.

She further added that the study will begin from Monday of which TSPCB officials will also be a part of. "Once we determine the spots from where the water is entering the lake, the TSPCB will collect samples from the lake and determine the toxicity levels. If the findings of the study reveals that the lake is indeed toxic and hazardous to the wildlife on campus, we shall look for solutions to divert the sewage water entering the lake or will try to treat it," said Harichandana.

The commissioner has also instructed the Gachibowli stadium authorities to set up sewage treatment units.Apart from this, even the university has constituted a committee to probe the pollution in the lake.

Expressing concern over the lack of accountability , environmentalists feared that the condition of the lake one among the four major lakes in UoH -will deteriorate further if the sewage inflow isn't stopped.

"We demanded the authorities that before the inspection is undertaken, the sewage should be stopped immediately. The tests and other rejuvenation programs can be done at a later stage," said Ravi Jillapalli, founder of Wild Lens, a wildlife protection group at UoH, who had previously petitioned to the PMO on this issue.
