The Allasandra lake and the Puttenahalli lake in Bangalore North may soon be rejuvenated with authorities of the Bangalore Water Supply and Sewerage Board (BWSSB) promising to stop flow of sewage into the two water bodies by February 20.
The BWSSB authorities agreed to stop sewage flow into the two lakes when Karnataka Upalokayukta S.B. Majage directed them to do so here on Sunday.
The Upalokayukta visited the two lakes and saw that sewage was being let to flow into the lakes and both the water bodies had been polluted.
At Allasandra lake, the sewage flows into the lake through two storm water drains – one connected to Yelahanka and another to Judicial Layout.
Mr. Majage said that as untreated sewage was entering the lakes, all efforts being made by Bruhat Bangalore Mahanagara Palike to develop the lakes was going waste. So, he said flow of sewage into the lakes should be stopped.
He also suggested that Karnataka State Tourism Development Corporation should provide boating facility at the Allasandra lake, and authorities concerned should develop aquatic life in the lake to attract birds.
While the BWSSB officials accompanying Mr. Majage said that flow of sewage into the lake would be stopped by February 20, the Bruhat Bangalore Mahanagara Palike officials promised to provide a temporary bund in the lake to act as natural filter to stop sewage polluting the entire lake. Yelahanka United Environment Association (YUVA) secretary B.M. Narayan said that the BWSSB authorities had also agreed to set up a sewage treatment plant near the lakes soon.
BWSSB has agreed to study the feasibility of commissioning a sewage treatment plan at the inlet points and Bruhat Bangalore Mahanagara Palike has agreed to fund 30 per cent of the cost of the plant, Mr. Narayan added.
