HYDERABAD: The trial runs for the sewage treatment plants (STPs) of three more highly polluted lakes Pedda Cheruvu, Mir Alam and Durgam Cheruvu will commence in September first week.
As part of the trial runs, the 10 million litres per day STPs of Pedda Cheruvu and Mir Alam and 5 mld STP for Durgam Cheruvu would begin to draw the sewage for testing the components and for `bacterial colonisation' required for decomposing the nutrient material nitrates and phosphates. The process takes about 20 to 30 days. The formal inauguration of STPs is expected to be in October, says Executive Director (GHEP), HUDA, K.S. Reddy.
HUDA had earlier restored Safilguda, Saroornagar and Langar Houz lakes that were once sewage cesspools under the lake restoration project taken up as part of Green Hyderabad Environment Programme. The STPs would treat part of sewage and let it into the lakes to maintain required lake water balance. The untreated excess sewage would be diverted from the lake through diversion channels into the Musi downstream.
The construction of 2.5 mld STD for another highly polluted lake, Patel Cheruvu would be completed by December or January. The restoration of lakes was taken up to check deterioration of ground water quality in the surrounding areas and to transform lakeshore area into lake parks for recreation of residents nearby, Mr. Reddy said.
Though a park in five-acre area near Mir Alam on the National Highway could not be developed as planned due to court case, other works like 6.5 km ring bund around the lake, fencing of the lake area, diversion channel and surplus weir and plantation of hedges, trees were completed, Mr. Reddy said.
For Pedda Cheruvu in Kapra municipality, 2.1 km ring bund was completed and fencing and walkway work was nearing completion, he added.
HUDA identified 18 highly polluted lakes for restoration by the end of 2006. But at least 11 such lakes would have to wait as residents who encroached the lakebed and constructed houses and `Shikam' pattadars had approached the court. The work on Nalla Cheruvu in Uppal, Rangadhamuni and Mysamma tanks in Kukatpally was stalled due to such disputes. Mr. Reddy said they requested the irrigation and revenue departments to demarcate the lake areas for settling encroachment issue.
