Mumbai: Four residential communities in Bengaluru will begin supplying treated wastewater to nearby industries under a water reuse initiative aimed at reducing dependence on freshwater resources.
The initiative is being implemented across Kolte Patil i-Towers, Nirman Layout, Himagiri Residency and Purva Palm Beach. Excess treated water generated from residential sewage treatment plants (STPs) will be further purified and supplied to industries located in Electronic City, Jigani and surrounding industrial areas.

The residential communities have partnered with Boson Whitewater, a water utility company that converts STP-treated water into high-quality potable water. According to the company, the water is processed to achieve low dissolved solids and hardness levels, making it suitable for various industrial applications while reducing the need for additional treatment.
Collectively, the four communities are expected to contribute more than 25 tanker loads of treated water every day. Each apartment complex is estimated to provide between 48,000 and 60,000 litres of treated water daily for industrial use.
Commenting on the initiative, Gowthaman Desingh Co-Founder, Boson Whitewater, said, “We need to rethink how we use and reuse the water that is already available within the city. Every day, residential communities generate large volumes of treated water that often have limited reuse avenues. Through these partnerships with apartments, we are creating a circular ecosystem where excess treated water from apartments is upgraded into high-quality industrial water and supplied to nearby industries. Our aim is to build a decentralised water reuse model that can help cities like Bengaluru improve water security while reducing dependence on freshwater sources.”
Pranjal Kumar, Resident of Kolte Patil iTowers, said, “We have been looking for sustainable ways to manage excess treated water from our STP. While we reuse it for landscaping and maintenance activities, there was still a significant surplus that required disposal.”
Rachita Bhujle, Resident of Kolte Patil iTowers, said, “This initiative provides a practical solution by converting that excess water into a resource for nearby industries. Apart from reducing our disposal costs, it also gives residents the satisfaction of knowing that water is being responsibly reused rather than wasted and also saving money in disposing of the excess STP treated water for the apartment.”
At Kolte Patil i-Towers in Electronic City, a 438-unit residential complex housing nearly 1,600 residents generates around seven tanker loads of excess treated water daily. The project is currently operational and supplies treated water for industrial reuse in the Electronic City region.
Nirman Layout in Jigani has established a 60,000-litre-per-day recovery system that enables up to five tanker loads of treated water to be supplied daily to nearby industries.
Himagiri Residency in Electronic City, a residential community with nearly 300 units, is expected to contribute around four tanker loads of treated water per day once operations commence by the end of June.

Purva Palm Beach, spread across a 19-acre campus and home to more than 10,000 residents, is expected to supply between eight and ten tanker loads of treated water daily for industrial use by the end of the year.
