NGT gives Delhi Jal Board four weeks to answer rainwater harvesting compliance claims

The National Green Tribunal has given the Delhi Jal Board four weeks to explain allegations that some rainwater harvesting and groundwater recharge systems in Delhi still breach its directions.

At a hearing on August 19, the tribunal considered an application alleging non-compliance by DJB, DDA, NDMC, MCD and NHAI. The applicant said some harvesting systems remained too close to stormwater drains, despite directions intended to prevent contaminated runoff entering groundwater during recharge.

The application also alleged that DJB had not installed piezometers near rainwater harvesting systems to track groundwater levels and the quality of recharged water. It claimed this had not been done despite nearly seven years since the original direction.

Recharge borewells must be at least five metres above the static water table, but the applicant alleged that several were 100, 200 or 400 feet below the water level. The Delhi Pollution Control Committee had issued show-cause notices to DDA and MCD in April 2025 over deficiencies, proposing interim compensation of Rs 5 lakh.

DJB's counsel sought time to obtain instructions and submit a further report. The matter is now listed for October 27.
