Bengaluru’s Bangalore Water Supply and Sewerage Board (BWSSB) is set to adopt the ‘Zero Bacteria’ technology, developed by the Indian Institute of Science (IISc), to improve the quality of treated water in apartment sewage treatment plants (STPs). BWSSB chairman Ram Prasath Manohar announced the initiative at the IGSTC Bilateral Workshop 2025, focusing on sustainable habitat solutions through AI and ML tools.
To promote sustainable groundwater management, BWSSB supplies 60 lakh litres of treated water daily to IT parks for air conditioning systems. A task force comprising IISc scientists, the Central Groundwater Authority, and BWSSB is monitoring borewells using AI-driven technology to prevent misuse, assess groundwater levels, and optimize water usage during summer.
Given that Bengaluru’s apartments generate large volumes of wastewater, STPs are now mandatory under the National Green Tribunal (NGT) order. Treated water is commonly used for gardening and cleaning, and some apartments even sell it. However, concerns over water quality have been raised by developers via CREDAI.
To tackle these issues, BWSSB is considering the ‘Zero Bacteria’ technology, which aims to enhance water purity and expand its usability. Manohar urged the scientific community to develop further solutions for wastewater treatment and access to clean, safe drinking water.
