The purpose of this study is to quantitatively investigate the effects of artificial recharge of treated wastewater of Meybod and Ardakan cities with infiltrations and injection wells and comparing the economics of the two alternatives. In this study, the simulation of the groundwater flow in aquifer for a one-year period of 2002-2003 was carried out using the MODFLOW model and three locations were selected for artificial recharge. The annual volume of treated wastewater to recharge was estimated at 13.2 million cubic meters and the average level increase within a radius of three kilometers from the artificial feeding site was about 0.8 meters. The price of each cubic meter of water extracted from artificial feeding, excluding the costs of transfer and treatment of wastewater by the infiltration basin method in feeding places No. 1, 2 and 3, is equal to 342.2, 417.4 and 9.381 rials and with the injection well method it was obtained as 506.2, 515.2 and 495.7 rials, respectively. The cost of transporting each cubic meter of water to places 1, 2 and 3 (which are 13200, 11000 and 9000 meters from the treatment plant, respectively) was equal to 3580, 2958 and 2418 rials, respectively. Therefore, choosing the right place is one of the most important points in the design of such systems.
