Synopsis: The BWSSB has launched a pilot project to supply recycled water to industries and commercial establishments along Bengaluru’s Outer Ring Road as part of a shift towards a circular water economy. The initiative is expected to produce 70,000 litres of recycled water daily from the Kadubeesanahalli sewage treatment plant, ease pressure on freshwater sources, reduce wastewater discharge and potentially serve as a scalable model for other cities.
The Bangalore Water Supply and Sewerage Board (BWSSB) is launching a pilot project to supply recycled water to industries and commercial establishments along the city’s Outer Ring Road as part of its effort to move toward a circular water economy.
The initiative will set up an advanced tertiary treatment plant to process treated water from the government’s 50 million litres per day (MLD) sewage treatment plant (STP) at Kadubeesanahalli in East Bengaluru.
The pilot is being implemented jointly by Boson Whitewater, a water utility company that converts STP-treated water into potable-grade water, and the BWSSB. The latter has provided space within the STP and will support the sale of recycled water produced during the pilot.
The plant will use Boson Whitewater’s 11-step water recycling system to generate 70,000 litres of high-quality recycled water every day, primarily for use in cooling towers of nearby industries and commercial buildings.
Officials said the project aims to reduce dependence on freshwater sources and prevent wastewater from being discharged into local water bodies.
BWSSB Chairman Ram Prasath Manohar described the initiative as a major step forward.
“First of its kind initiative where high quality water is recovered from the treated waste water and supplied to IT parks, industries and commercial buildings for their secondary applications. BWSSB always appreciates water re-use efforts,” he said.
Vikas Brahmavar, Co-Founder of Boson Whitewater, said the pilot demonstrates how Bengaluru can rethink its water management systems.
“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,” he said.
Boson Whitewater was selected as one of the six grantees from more than 500 applications under Titan Company Limited’s Design Impact Awards initiative. Each beneficiary receives ₹50 lakh in the first phase, along with additional support from Villgro and Sattva Consulting.
In the initial phase, the recycled water will be transported via tankers to consumers. Over time, officials said the model may be expanded to other STPs across the city, with the long-term possibility of establishing a pipeline network linking STPs directly to industries.
The project is expected to serve as a replicable model for other cities worldwide that rely on centralised wastewater treatment systems.
