Four software behemoths have come together to sponsor a Sewage Treatment Plant that can treat 1 million litres of sewage flowing daily into the Mahadevapura lake.

The 26.23-acre lake was rejuvenated recently at a cost of ₹6 crore. However, as the sewage from its four inlets were diverted, water was not flowing into the lake.

The STP, however, will ensure that a minimum of 1 MLD of treated water enters the lake. “This will compensate for the evaporation and other losses of the lake, and ensure the water levels remain steady,” said Manish Michael, Chief Executive Officer of United Way Bengaluru (UWBe) that coordinated with Amazon, Mphasis, Dell, and HTC Global to raise funds for the STP.

The foundation stone for the STP was laid on Thursday, and it is expected to be operational within five months. With the lake having filled to the brim owing to heavy rain, Mr. Michael expected the STP to maintain a steady water level even during summer.
