Boson Whitewater, a water utility company specializing in converting treated wastewater into potable-quality water, has partnered with the Bangalore Water Supply and Sewerage Board (BWSSB) to launch a pilot project at the Kadubeesanahalli Government Sewage Treatment Plant (STP). The initiative will supply 70,000 litres of recycled water every day to industries and commercial establishments along the Outer Ring Road.
The project was selected as one of six grantees under the Design Impact Awards initiative by Titan Company Limited, chosen from over 500 applications. Each grantee receives a grant of Rs. 50 lakh in the first phase, with additional support from Villgro and Sattva Consulting.
At the heart of the pilot is an advanced tertiary treatment plant that processes water from the government’s 50 MLD STP through Boson Whitewater’s proprietary 11-step recycling system. The recycled water will primarily be used in cooling towers, reducing dependence on freshwater and preventing wastewater discharge into local water bodies.
BWSSB Chairman Ram Prasath Manohar praised the initiative, stating: “First of its kind initiative by BOSON where high quality water is recovered from the treated waste water and supplied to IT parks, industries & commercial buildings for their secondary applications. BWSSB always appreciates water re-use efforts.”
Vikas Brahmavar, Co-Founder of Boson Whitewater, added: “This pilot demonstrates how Bengaluru can move towards a true circular water economy. By supplying 70,000 litres of high-quality water every day, we are not only conserving precious freshwater but also ensuring that treated wastewater is put to productive use within the city. If scaled, this model can transform how our city manages its water.”
BWSSB has provided space for the pilot and will support the sale of recycled water generated. Initially, supply will be managed through tankers, but future plans include expanding the model to other STPs across Bengaluru and potentially building a pipeline network to directly connect treatment plants with industries.
If successful, the Kadubeesanahalli pilot could serve as a scalable model for cities worldwide, demonstrating how centralized wastewater treatment systems can be leveraged to create sustainable, circular water economies.
