Nowadays, water management through the use of non-conventional water resources has gained attention as a means of reducing pressure on local natural water resources. One of the most widely used non-conventional water resources is treated wastewater, or effluent, which has been the subject of numerous studies, and whose benefits are recognized worldwide. In the process of effluent utilization, the location of the wastewater treatment plant is of great importance. To determine the most suitable sites for WWTP construction, large-scale zoning of suitable and restricted areas based on various effective criteria is essential. In this study, after examining the criteria required for zoning, suitable and restricted areas for WWTP construction in Isfahan were identified by defining the most important siting criteria in GIS software. For this purpose, nine constraint criteria were used, including slope, rivers, the 25-year floodplain, faults, power transmission lines, transportation networks, protected areas, urban and rural residential areas, and population centers. The results showed that 612.90 km² (39.13%) of the total study area was suitable for WWTP construction, whereas 953.55 km² (60.89%) was restricted. The results also indicated the significant influence of population centers and urban and rural residential areas on the spatial suitability pattern. The highest percentages of restricted land were associated with population density (45.67%), urban areas (34.65%), and population centers (29.09%). In contrast, the lowest shares of restricted land were associated with minor roads (0.25%), protected areas (0.65%), and power transmission lines (0.91%). The final spatial suitability map showed that one of the existing WWTPs is located within a restricted area.
