The Bangalore campus of Amrita Vishwa Vidyapeetham has implemented an effective rainwater harvesting system to sustainably manage and utilize rainwater, supporting groundwater recharge, gardening, and flushing.

 Key Elements of the Rainwater Harvesting System

Harvesting of Surface Runoff and Rooftop Rainwater

  •  Surface runoff is strategically directed to recharge groundwater through specially designed structures around the campus. 
  •  Rainwater from rooftops of the Academic Blocks, Guest House, and Staff Quarters is channeled into recharge pits to enhance groundwater levels.

Recharge Pits and Aquifer Recharge

  • 39 recharge pits across the campus, each with a diameter of 1 meter and a depth of 3 meters, are used to promote percolation of rainwater into the ground. 
  • Bore wells located near Girls and Boys Hostels (A, B, and C Blocks) are recharged using rooftop rainwater, ensuring year-round groundwater replenishment.

Storage Tanks

  •  Collected rainwater from the Boys’ Hostel (Mathura Block) is stored in two tanks with capacities of 40 KL and 90 KL. 
  •  An additional 40 KL storage tank located behind the STP unit collects rainwater, further enhancing water storage capacity for non-potable uses.

This system exemplifies the campus’s dedication to sustainable water management, showcasing how rainwater harvesting can support environmental conservation and efficient resource use.
