deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and, is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone.[1] Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and or reclaimed water is routed to the subsurface.
Explanation:
RWH involves the process of diverting rainwater from surfaces to tanks or into the ground, for use at a later stage. Underground tanks can be used, to store the rainwater and it can be used for flushing or gardening. However, the amount of water that can be stored, is limited by the size of tank. Hence, an alternative method, is to dig bore-wells in the ground and divert the rainwater into it, to recharge the ground water. From bore-wells, this potable water can be pumped for daily use.
By using harvested rainwater, housing complexes and individual households can reduce their dependence on municipal water supply and/or water tankers and thereby, save money. Shaishav Dharia, regional CEO of the Lodha Group, points out that “Many developers have already installed rainwater harvesting systems in their projects. Some have also installed large Reverse Osmosis (RO) plants, to treat water from bore- wells, which would be recharged by rainwater harvesting.” Such integrated methods are necessary, to ensure availability of water, for residents, he maintains.
