Water management is very important task in countries that have water shortage. Agriculture is the largest user of water in the entire world. Wastewater reuse is one of the main options that can be considered as a new source of water in regions where water is scarce. The main purpose of this study is to determine the feasibility of Isfahan’s north wastewater treatment plant effluent for agricultural irrigation. To evaluate suitability of treated wastewater forirrigation, important indicators like Sodium Adsorption Ratio (SAR), Soluble Sodium Percentage (SSP) and Potential Salinity were investigated. In this study the SAR value foreffluent was 2.62 and according to approved criteria by Food and Agriculture Organization (FAO) it was excellent for irrigation, SSP was 39.7% so it has good quality for irrigation usage and the potential salinity was 4.81 meq/L, thus according to approved criteria by FAO it is medium for soil permeability. Also the EC value of effluent was 1250 μS/cm (1.25 dS/m)and according to approved criteria by FAO it was permissible for irrigation
