Charging for collection, removal, transport and final destination services is not an easy task, since it should be implemented for a divisible service and the issue is how to measure waste generation. The current charging model, which consists of dividing total costs by number of users, taking into account the built area of the residence and IPTU, is considered unconstitutional. Cities, autarchies and companies responsible for waste management have been trying to find ways to solve this problem by modifying ways and equations for charging. However, few studies in this field were able to provide a practical and fair equation that considers waste production in each residence, which would guarantee the divisibility of the service, i.e. the payment for the amount of solid waste generated. By determining the correlation between waste production and water consumption, this study proposes and analyzes models for charging which enable the financial sustainability of collection, removal, transport and final destination services for urban solid waste produced in Viçosa. The relation between water consumption and solid waste production in each building was determined by regression analysis. Solid waste and water consumption data were obtained for each building (distribution meter), except for large waste producers. The equations were obtained from the regression analysis including factors such as the activity performed at each building; socioeconomic zoning of the municipality and unit cost of the kilogram of collected residue. The proposed models for charging proved to be adequate to promote the economic sustainability of the services once the simulation showed an important increase in service tax revenue.
