Iran receives 400 billion cubic meters of precipitation annually, 70% of which is lost due to surface evaporation or runoff. Of the approximately 90 billion cubic meters of water consumed by the country, more than 50% is supplied by groundwater resources. Therefore, managing water supply through groundwater reservoirs (tables) is very important. In artificial recharge methods with a flood spreading approach, they often become evaporation ponds after a period of 3 to 5 years due to the high volume of sediments and, in practice, instead of water infiltration, they cause evaporation and water waste. The method proposed in this article is a solution to overcome the two issues of flooding and surface evaporation in water supply. In this method, during the rainy season, river water is added to the aquifer through injection wells after the containment and purification process, and during the hot season, it will be possible to exploit it through production wells.

In this study, the technological background was studied along with a case study of process design in one of the aquifers in the country. In addition to preparing a reliable computer model of reservoir behavior and water hydrodynamics in this porous environment, the effect of injection on increasing the water level in the aquifer was studied for 8 injection scenarios from 1 to 20 million cubic meters. Using Prosper software, the pressure drop in the well column and the injection flow rate were studied. The results of the technical section showed that in this aquifer, there is a daily injection capacity of 10 thousand barrels of water for the defined wells without the need for additional pressure.

Also, an economic evaluation of the investment amount, final cost and project revenues was estimated. The results show that this technology has the potential to increase storage efficiency in the country's watershed management plans. Also, the final cost of water storage and supply is much more economical than the method of dam construction, desalination and water transfer.
