Site Selection and Designing of Landfills for Rural Solid Wastes in Roudab, Sabzevar

considering the growning population and the consequent increase in the amount and the varieties of wastes during land life in recent years, management of solid wastes is of great importance. The aim of this study was to present a suitable design for the hygienic disposal of wastes in the rural regions of Roudab, Sabzevar. In this research the quality and quantity of wastes, methods of collection, disposal and site selection for solid wastes from summer 2006 to spring 2007 for one year was investigated. In this study, suitable sites for the disposal of wastes were determined and eventually the site for waste disposal was designed on the basis of different standards using several models of information, including road maps with the guide Leopold matrix. Through field visits, two locations for comparison and evaluation through hierarchical analysis process were selected and studied throuthly. Giving appropriate weight to each of the locations, the final location was selected. The two selected sites were then assessed for their environmental impacts. Results showed that both sites were suitable for landfill solid wastes for the Roudab area. The needed area for the landfill site was 100000 m2 The current situation and method of collection and disposal of solid wastes in Roudab is not suitable. Therefore, considering the above results and in order to prevent invironmental pollution the establishment of a suitable management system for organization of solid wastes in the Roudab area is imperative.
