Ready for inauguration by month-end after restoration

HYDERABAD: Yet another highly polluted lake gets transformed into a clean and pleasant looking lake, enhancing the ambience of surrounding colonies.

The 97-acre Peddacheruvu at HMT Nagar near Nacharam of Kapra municipality was once a highly polluted lake with unbearable stench due to direct release of effluents from industrial areas of Uppal and Nacharam and domestic sewage of surrounding habitations.

After HUDA has taken up conservation and restoration of the lake under the Green Hyderabad Environment Programme two years ago, the first thing it has done is to construct a ring bund along the FTL of the lake to prevent further encroachments. Subsequently it has set up a 10 mld sewage treatment plant to treat sewage before letting it into the lake, beautification of the lake bund, walkway and landscaping at a cost of Rs.20 crore.

The inlets carrying industrial effluents have been diverted to a trunk main executed by Metro Water Supply and Sewerage Board (HMWSSB) downstream to Musi. The HUDA has deposited Rs.5 crore as its share with the water board for the diversion work. It has also deposited Rs.2.3 crore with Kapra and Uppal municipality for the underground sewerage system in the habitations surrounding the lake.

HUDA Chairman D. Sudheer Reddy, accompanied by Executive Director, Urban Forestry, K.S. Reddy, and Chief Engineer Vivek Deshmukh inspected the STP and the lake on Friday and said it would be ready for inauguration by month-end along with Saroornagar Park.

The tertiary treatment plant, running for the last few month, had stabilised with better parameters of BOD, COD, TKN (potassium and nitrates), total suspended solids for treated lake water, said Mr. Deshmukh.

Biological filtration to reduce presence of nutrients was the unique feature of Pedda Cheruvu STP as it would eliminate the seasonal menace of algal bloom commonly found in all lakes, according to S. Kishore of Degremont Company that constructed the STP.

As the capacity of STP was 10 mld, the excess sewage and industrial effluents were being diverted downstream of the lake thus preventing its flow into the lake, officials said.

Of the 18 highly polluted lakes taken up for restoration under GHEP, seven had been completed. The remaining would be taken up under JNNURM funding, they said.
