Groundwater recharge, also known as deep drainage or deep percolation, is a water cycle stage. In this stage, water travels down from the surface to an underground area called an aquifer. This downward journey is mainly how water accesses an aquifer. This usually happens below the level of plant roots in an area called the vadose zone. Often, it's described as a flow to the water table's surface. Additionally, groundwater recharge involves water moving beyond the water table deeper into the saturated zone. Rainwater harvesting solution collection is an easy and effective technique to lessen your reliance on outside water sources and conserve water.
