The document discusses GRIHA criterion 18 for promoting rainwater recharge into groundwater aquifers. It awards up to 2 points for projects that recharge surplus rainwater through appropriate filtration measures. Projects are exempt if the local groundwater authority recommends against recharging due to a high water table. Compliance requires submitting details of the rainwater harvesting and filtration system to prevent aquifer damage from recharged water.

1. GRIHA CRITERION 18: Rainwater Recharge

2. Intent:
The intent of this criterion is to promote the recharge of
groundwater aquifers.
Maximum Points: 2

3. Non-applicability:
If the CGWB norms suggest that the ground water table is
high and ground water recharging should not be done, then
the project is exempt from this criterion

4. Appraisals:
Recharge of surplus rainwater into aquifer (through appropriate
filtration measures) – 2 points

5. Compliances:
Submit details of rainwater harvesting for ground water
recharge and its filtration system to show that adequate
preventive measures are being taken to avoid damage to the
aquifer by the recharged rainwater
