Bangalore Water Supply and Sewerage Board (BWSSB) announced plans to furnish zero-bacterial treated water to prominent technology firms like Wipro and defense PSU Hindustan Aeronautics Limited (HAL). The initiative, spearheaded by BWSSB chairman Ramprasad Manohar, underscores a pioneering indigenous water treatment technology, endorsed by scientists from the Indian Institute of Science (IISc).
According to Manohar, the demand for zero-bacterial water has surged, with firms like Wipro seeking substantial quantities. For instance, Wipro has requisitioned three lakh liters daily, accounting for a quarter of its overall water usage, predominantly for non-potable purposes such as landscaping, sanitation, and cooling systems. The treated water, distinguished by its lower Total Dissolved Solids (TDS), offers a cost-effective alternative to borewell water, which is both expensive and high in salt content.
Highlighting the versatility of the zero-bacterial treated water, Manohar clarified its suitability for all purposes except drinking. BWSSB stands prepared to produce up to 1 crore liters of treated water daily, a testament to its commitment to sustainability and innovation.
The innovative technology is being deployed at STPs in key areas such as Agra, KC Valley, and Bellandur, especially in zones with multiple tech parks. Rigorous testing by IISc scientists has validated the water’s zero-bacterial quality, both onsite and in labs.
Manohar highlighted the potential of enhanced treated water availability in easing pressure on vital resources like Cauvery water. With increasing interest from tech parks, BWSSB aims to supply around 1 crore liters of treated water to these sites soon.
He mentioned talks with ORRCA, leading to treated water provision. HAL, among others, showed interest in the solution. Bengaluru generates 1800 MLD sewage daily, with STPs treating around 1200 MLD, reflecting proactive water management.
