What is Aquifer Recharge
There are two types of aquifer recharge (AR): 1 - Natural recharge and 2 - Artificial aquifer recharge. Natural recharge is precipitation, river bed seepage, flooding and other natural forms of water that enter the groundwater system. Artificial aquifer recharge is the enhancement of natural groundwater supplies using man-made conveyances such as infiltration basins, field flooding, infiltration galleries or injection wells. Often, AR is conducted to improve groundwater resources (i.e. increasing storage) and is often incorporated into a broader water resource plan.
