One of the key points in providing healthy conditions for people is to prevent water-borne diseases. Therefore, wastewater treatment plants play an important role in promoting public health and environmental protection. Following the establishment of rural water and wastewater companies in Iran, sanitary disposal of wastewater may be considered through a comprehensive plan.
Having the mentioned objectives in mind, the researchers planned the present study. With the major goal of presenting an optimal strategy and methods for treatment and disposal in rural areas throughout the country and after collecting basic information on the situation of villages in Iran (population, climate and water supply), the research was conducted.
First, the necessary data about the sewage collection and disposal system were gathered through questionnaires. Second, based on the fundamental criteria of sewage collection needs, villages were classified and ranked. Villages were classified into 6 groups based on the conditions of climate, ground water table and soil structure. Of course, our conclusions must be considered as guidelines. For a decisive conclusion, it would be necessary to consider local specifications and very special conditions as other sub-criteria in the study.
