The method of injecting water into groundwater for the purpose of storage generally has several reasons. For arid and semi-arid regions such as Iran, where surface water storage increases its evaporation due to hot weather, priority is groundwater storage. In the current situation, that climate change has caused several problems, especially in the area of lack of access to freshwater; storage is a very important solution for the countries involved in the water challenge. In addition, for areas near the coast, extraction of groundwater causes interference with fresh and salty water and a decrease in the quality of groundwater. Because of the vastness of Iran and the presence of warm and dry areas as well as coastal areas and population density in coastal areas, there are problems with the evaporation of water and the interference of fresh and salty water in our country. In addition, due to different types of water storage methods, the ASR method is one of the methods that, if used correctly, helps to reduce the overall cost of water production. Considering that about 11% of the area of Iran is in the form of a karst aquifer, part of this article deals with this type of aquifer and how water is stored in it.
