KSPCB launches project to fill up Puttenahalli lake

The Karnataka State Pollution Control Board (KSPCB) on Sunday, launched an experimental project to let treated sewage water from apartments in JP Nagar 7th Phase into the Puttenahalli Lake.

The decision was taken after Upa Lokayukta Justice Subhash B Adi and KSPCB Chairman Vaman Acharya visited the polluted and dying water body on March 28. Speaking to Deccan Herald, Dr Acharya said the treated sewage water from apartments along with rain water will fill the Puttenahalli lake to its brim in another 10 months.

The process will be slow because there is no channel to let the drain water into the lake, he said.

“The KSPCB, the Bruhat Bengaluru Mahanagara Palike (BBMP) – who are the custodians of the lake – and the apartment association have entered a tri-party agreement. The association will monitor the lake. A four member committee has also been set up, with one person each from the KSPCB, BBMP and the apartment association to monitor the daily activities of the lake. We have also invited the fisheries department to introduce fish into the lake which will improve the lake water quality and act as an indicator,” said Acharya.

The lake bed is spread across 10 acres and has a capacity of 200 million litres.
There are 18 apartment blocks in the vicinity housing about 2000 flats. Thus, through a 1100 kilo litre sewage treatment plant, the lake will be filled to its capacity. Two acres of the lake was also encroached upon and this was cleared under the Lokayukta directions. The L&T apartments will discharge about 0.8 mld water every day and with this alone it will take 250-275 days for the lake to fill up, he said.

Similar projects

After the experiment at the Puttenahalli lake, the KSPCB will start similar projects at the Sarakki lake next month, followed by the Madiwala lake, Varthur lake and Yemalur lake.
“We are starting from Bengaluru South, because water flows into the main lakes from here. Gradually we will reach the 900-acre Belandur lake. Later, the same will be extended across the City. Talks are on with the BBMP to take such measures at six of their lakes and with the BDA for another six lakes,” Dr Acharya said.
