Amid Growing Water Crisis, Chandigarh University Biotechnology Researchers Get Patent for Innovative Device to Kitchen Wastewater Reuse, Save Potable Water

CU Researchers Patent Two-Stage Filtering Device to Address Water Scarcity with Recycling of Kitchen Wastewater for Gardening, Cleaning and Other Uses CHANDIGARH, India , Aug. 29, 2026 -- At a time when 80% of water supplied to households in India is released as wastewater even as over 60 crore people in the country are facing severe water crisis due to extreme groundwater over-extraction, erratic monsoons and rapid urbanisation, a team of Chandigarh University (CU) researchers has conceived and patented an innovative wastewater filtering device designed to provide a two-stage treatment for kitchen wastewater before it enters the drainage system, while also enabling collection of the filtered water for suitable domestic uses including gardening, irrigation and outdoor-area cleaning, thus reducing the demand for fresh potable water.
