Environmental protection is being considered as one of the main dimensions of sustainable development. It is argued that other aspects of development directly and indirectly are associated with this issue. The major domains of Iran’s resources are located in rural areas. Thus preservation of these resources is the prime responsibility of rural settlements. Appropriate management and location of analysis regarding rural waste sanitation fields are being considered as prominent measures as far as rural environmental issue is concerned. Many methods and techniques are available for this type of location of analysis. Flexibility and evolutionary nature of ordering weighing average technique (OWA), led to application of this method. Moreover, Fuzzy as well as GIS techniques were used for this type of locational analysis in Vill of Qaleh Dareh-C in Makoo County. This in turn demands selection of 11 indices. The results using different models of OWA were classified in seven classes. This study suggests that taking into account low risk, balance and accuracy issues shown in different maps, OWA is a very good option and is capable of determining 21.5 km2 domains as a prime location for installing west sanitation in the study area.
