Nowadays, one of the financial and environmental problems faced by cities is related to the adequate final disposal of solid waste in municipal sanitary landfills. The selection of the areas implies in several factors as the proximity of watercourses, soil resistance to contaminating effects, protection of conservation areas, size of the area available, distance between collection and disposal, which are the main issues that make the topic relevant. Thereby, was employed a methodology to assess the potential for selected of areas with the capacity to receive a landfill, considering as the study areas intercropping municipalities, by using techniques of Geographic Information Systems. The method used, considered as criteria of exclusion for unsuitable areas, the airport security zones, conservation unities and others operational and technical aspects of environmental, weighted according to their influence within the theme, generate the ranking of the most suitable areas for 20-years operation of landfill installation. Therefore, after applying the criteria, it was found that less than 50% of the entire region area is suitable for such an initiative leading to 31ranked sites with great aptitude to implementation of the landfill sanitary, according to multicriteria analysis by weighted overlay.
