Why Groundwater Recharge Systems?

It is no secret that Bangalore has been facing water scarcity problems. Borewells are going dry as the water table falls by an estimated 7 percent each year. One of the reason for this depletion is that the amount of water infiltrating into the ground is decreasing as more concrete structures are added and Bangalore continues to expand and develop. Instead of losing rainwater as run-off, a groundwater recharge system can be built to meet water needs for at least 3-4 months a year, and use the overflow water to recharge the groundwater. It will help you meet your water needs and those of next generations.
