Four residential communities across Bengaluru will soon supply treated wastewater to nearby industries.The communities at Kolte Patil i-Towers, Nirman Layout, Himagiri Residency, and Purva Palm Beach will collectively contribute more than 25 tanker loads of treated water daily, averaging 48,000 to 60,000 litres per apartment per day, to industries in Electronics City, Jigani and surrounding areas, in a bid to help reduce their dependence on freshwater resources.Excess treated waterThe apartments have partnered with Boson Whitewater, a water utility company, to convert excess treated water from residential sewage treatment plants (STPs) into high-quality 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 further treatment.Pranjal Kumar, a resident of Kolte Patil iTowers, said that while the residents have been using treated water for landscaping and maintenance activities, there was still a significant surplus that required disposal.“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,” said Rachita Bhujle, another resident of the apartment.The 438-unit residential complex, housing nearly 1,600 residents, generates approximately seven tanker loads of excess treated water every day, which is now supplied for industrial reuse in the Electronics City region.Commencing soonAt Nirman Layout in Jigani, a 60,000-litre-per-day recovery system has been established, enabling up to five tanker loads of water to be supplied daily to industries in the Jigani industrial area.Himagiri Residency in Electronics City is expected to contribute around four tanker loads of treated water per day by the end of June, while Purva Palm Beach is expected to supply eight to ten tanker loads daily for industrial use by the end of this year.“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,” said Gowthaman Desingh, co-founder, Boson Whitewater, said.
