Bengaluru’s Water Supply and Sewerage Board has adopted a decentralized wastewater treatment policy requiring all new apartment complexes (200+ units) to install on-site treatment plants (STPs) with ≥90% reclamation. Reclaimed water is used for landscaping and flushing. In the first year, six complexes have been certified, saving 150 ML of fresh water annually. The board offers grants for retrofitting older properties. Environment experts view this as a game‑changer for urban water sustainability in India.
