Rain Water Harvesting in Bangalore Apartments — your questions

Is rainwater harvesting mandatory for apartments in Bangalore?+
Yes — BWSSB mandates rainwater harvesting for buildings on plots above a specified size, as part of Bangalore's broader water conservation regulations.
How can I verify a building's RWH system is actually functional?+
Ask the builder or association for RWH compliance documentation, and where possible inspect the recharge pits or storage system during a site visit rather than relying on paperwork alone.
How does Relgrow verify a project before listing it?+
Every project shown for RWH-compliant listings is checked against the Karnataka RERA portal, along with khata type and sanctioned building plan, before it's added to any shortlist.
