Groundwater Recharge Program

Groundwater Recharge Program


This program aims to address water scarcity with rainwater conservation and percolation pits.

Recharging ground water through aquifers is the most sustainable method of storing natural water. It is a program to enhance the depleting groundwater levels by conserving rainwater. The intervention involves an integrated approach where social, technical, and environmental aspects are blended. The goal of the program is to build percolation pits and thereby conserve liters of rainwater every year.

The Need

Rainwater is a natural water recharger, when not managed well it can lead to water scarcity. Rain water wastage is the most common existing issue which often leads to imbalance in the existence of groundwater, resulting either in flooding or drought.

The Benefits

The project is helping water conservation by permeating rainwater to better storage facilities.

  • Conserve and implement rainwater harvesting for sustainable resource usage.
  • Ensuring water security by recharging percolation pits through rainwater.
  • Improve quality and accessibility of water resources for local communities

Our Intervention

  • Under the intervention, percolation pits are made to ensure the rise in the water table by about 20 feet (about six meters)

  • It works towards ensuring water security by recharging groundwater and helps in the growth of trees and plants in the Bio-diversity Park as the moisture in the soil will be a great benefactor for trees and plants. Rainwater does not get stored in the big parks and it finally reaches the storm water drain. With the implementation of percolation pits, there will be no water logging or wastage of water due to these rainwater harvesting pits. Rain water harvesting also helps in the growth of trees and plants in the Bio-diversity Park as the moisture in the soil will be a great succor for trees and plants. There will be lesser dependency on water sources, especially borewells at the park and surrounding residential areas in the future.


15,000+ beneficiaries across various project sites in Bengaluru, Karnataka
