MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611024047 A) filed by Chandigarh University, Mohali, Punjab, on Feb. 28, for 'a building-integrated system for electricity generation and groundwater recharge.'

Inventor(s) include Dr. Navdeep Singh; Dr. Asha Deepak Bhatia; Sanjeev Jain; Dr. Sandeep Salhotra; Dr. Jagdeep Singh; Dr. Muklesh Kumar Tiwari; Dr. Sharneet Singh Jagirdar; and Dr. Nihal.

The application for the patent was published on May 1, under issue no. 18/2026.

According to the abstract released by the Intellectual Property India: "The present invention relates to a building-integrated method and system for recovering gravitational potential energy from greywater in multi-storeyed buildings. Greywater from kitchen sinks and bathtubs is selectively collected from predetermined upper floors to ensure a minimum hydraulic head. The collected greywater is stored in an intermediate reservoir, filtered, and conveyed downward through a vertical penstock under gravity to drive a micro-hydro turbine coupled with an electrical generator, thereby producing renewable electricity. The turbine outflow is captured and directed into infiltration basins and/or recharge wells for controlled groundwater replenishment instead of discharge into municipal sewers. The present invention enables cascading utilization of wastewater for both decentralized energy generation and urban water sustainability within the building itself. The system is scalable, cost-effective, and suitable for residential and commercial high-rise structures."
