Water harvesting ponds collect and store rainwater runoff from surrounding areas, preventing it from flowing away and allowing it to be stored for future use. By capturing rainwater, these ponds help reduce soil erosion and prevent surface runoff, thereby protecting the landscape and maintaining soil fertility. These ponds facilitate the recharge of groundwater aquifers by allowing rainwater to percolate into the ground, replenishing underground water sources. These ponds create habitats for various wildlife, including birds, amphibians, and insects.

This rainwater harvesting pond at GIM has a capacity of 800 cum. A pump of 5000 LPH capacity along with a filtration unit ensures water reuse (for flushing) in the hostel blocks or faculty housing during water scarcity. It drains out in 3-4 months after which it is filled again by bore well water. The wildlife found here includes Muscovy ducks, Yellow-billed ducks, and Malabar gliding frogs.

It aligns with SDG Goal 6: Clean Water and Sanitation, Goal 11: Sustainable Cities and Communities, Goal 13: Climate Action, and Goal 15: Life on Land.
