This study aimed to identify problems arising from lack of knowledge in interest groups about wastewater reuse and Delphi survey was conducted. According to experts, the most important factor that may cause the public resistance against the use of treated wastewaters is “health concerns”. This factor may be resulted from “lack of trust on the responsible organizations” and “ignorance about treatment processes”. Experts believed that the main concern for the use of treated wastewater by farmers is their concerns about production of “unhealthy crops” that could affects on “products market”. According to experts, these problems can be caused by “lack of farmer’s awareness about quality standards of irrigation water” and “unfamiliarity to the wastewater treatment processes”. On the other hand, “lack of skill” in experts in responsible organizations and “unfamiliarity about new sciences and technologies”, resulting in “inefficient wastewater treatment” and together with “lack of understanding about public attitudes”, lead to inefficient implementation of wastewater reuse projects. According to experts, first factor affecting policymakers and regulators sights about wastewater recycling projects to ratify necessary legislation and funding, is giving an “understanding about sustainable development” to them and inform them about “socioeconomic benefits” of wastewater recycling projects.
