New STP to keep 12 MLD sewage off lake

Treated water from the new sewage treatment plant (STP) in the upstream of Bellandur lake will be diverted to waterbodies in Kolar district. The STP with a capacity of 60 MLD (million litres per day) has come up at B Nagasandra, Yemalur, near Embassy Golf Links. Built at a cost of Rs 201 crore, the plant has been built by the Bangalore Water Supply and Sewerage Board (BWSSB) with financial assistance from the Japan International Cooperation Agency (JICA).

The plant is equipped with Biological Nutrient Removal (BNR) technology besides a biogas engine that will help generate 1 MW electricity daily. Wastewater from Kanakapura Road and Sarjapur Road will reach the plant via a canal of Agara lake. This way, about 12 MLD of sewage water can be stopped from going to Bellandur lake every day.

CM on Bellandur lake
Chief Minister Siddaramaiah, who inaugurated the STP, said: “We are developing Bellandur and Varthur lakes and will take up Rampura lake later. We are ready to allocate the required funds for the development of lakes.”

Bengaluru Development Minister K J George said the government had formed an expert committee for developing Bellandur lake besides an implementation committee. “Tenders were invited in the first phase. The committee asked for calling the tenders again. But before a direction on the re-tender could be given, members of the expert committee approached the NGT so as to take credit for cleaning the lake. In reality, all the work is being done by the government.”
