City apartment complexes to supply treated water to nearby industries

Bengaluru: Four residential communities across Bengaluru will soon supply treated wastewater to nearby industries. The initiative, implemented across Kolte Patil i-Towers, Nirman Layout, Himagiri Residency, and Purva Palm Beach, enables excess treated water from residential sewage treatment plants (STPs) to be further purified into high-quality water and supplied to industries in Electronic City, Jigani, and surrounding industrial areas.

Each of these apartments have partnered with Boson Whitewater, a water utility company that converts STP-treated water into high-quality potable water. The treated water supplied through the initiative is processed to achieve low dissolved solids and hardness levels, making it suitable for various industrial applications and reducing the need for additional treatment. Collectively, the four residential communities will contribute more than 25 tanker loads of treated water daily, averaging 48,000 to 60,000 litres per apartment per day, reducing dependence on freshwater resources for industries.

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
