If you're on your apartment complex's owners association, RWH compliance is probably not something anyone's checked since the builder handed the property over. That's usually where the problem starts.

Who's responsible after handover

Builders install RWH systems to get their occupancy certificate, but once the property is handed over to residents, ongoing compliance and maintenance responsibility shifts to the owners association (OA). Many OAs don't realize this transition happened, or assume the builder's original installation is still functioning correctly years later without anyone having checked.

Common problems in apartment RWH systems

  • Never maintained since handover — filters clogged, recharge pits silted up, sometimes for years
  • Undersized for the actual roof area — some builder installations meet minimum compliance but don't handle the complex's full runoff effectively
  • No one owns the responsibility — without a specific committee member or vendor assigned, RWH maintenance falls through the cracks between facility management and the OA

Getting the OA to act

If you're raising this at a committee meeting, the practical starting point is a professional assessment — get the current system inspected and documented, so the OA has concrete facts (is it compliant, is it functioning, what would it cost to fix) rather than a vague sense that "someone should check on this."

Cost for apartment complexes

RWH installation for apartment complexes typically runs ₹80,000-₹1,50,000, scaled to the number of downpipes, total roof area, and recharge system design the property needs. Getting an existing system properly assessed and repaired is usually a smaller cost than a full new installation.
