How to Solve Issues with Old & Failed Rainwater Harvesting Systems in Delhi NCR

The Problem: When Rainwater Harvesting Exists, But Doesn’t Work

Across Delhi NCR, thousands of housing societies technically have Rainwater Harvesting systems—but in reality, most of them are non-functional.

Over time, we commonly find:

  • Recharge pits completely choked with silt and debris
  • Filter chambers damaged, missing, or never maintained
  • Stormwater pipelines blocked or incorrectly connected
  • No inspection chambers for cleaning and monitoring
  • Systems constructed without proper engineering or testing

These systems may look fine on paper, but actual groundwater recharge is zero.

The consequences are serious:

  • Notices and penalties from Delhi Jal Board
  • Repeated waterlogging during monsoon
  • Wasted capital investment
  • Continued depletion of groundwater levels

In most cases, societies assume the only option is to build a new system, when the real solution is repair and retrofit.
