Concept of Artificial Recharge (AR) of Groundwater by Injection Wells

Artificial Recharge (AR) of Groundwater by Injection Wells refers to a method of enhancing the natural replenishment of groundwater (or aquifers) by actively injecting water into the ground using specially designed wells. This process is used to increase the amount of water stored in aquifers, typically to meet water demand, mitigate land subsidence, prevent saltwater intrusion, and reduce surface water runoff, such as floodwaters. It’s a vital tool in regions facing water scarcity or those needing to balance groundwater use with conservation. Artificial recharge (AR) of groundwater is a process that involves the deliberate addition of water to aquifers to replenish groundwater reserves and mitigate the negative effects of excessive groundwater extraction. One of the most effective methods for artificial recharge is through injection wells, where water is injected directly into the aquifer. This technique has gained significant attention as a solution to address issues such as groundwater depletion, land subsidence, and saltwater intrusion, as well as to mitigate the challenges posed by stormwater runoff. This literature review explores key studies, trends, methodologies, challenges, and benefits of artificial recharge via injection wells.
