Resumo: The aim of this study was to propose a new model of charging for water use which considers the granted rights, the capitation volumes, and the discarded domestic sewage. For this purpose, the main charging models applied in federal river basins, implemented by the ANA, were analyzed: Paraíba do Sul river, Piracicaba, Capivari and Jundiaí rivers, and São Francisco river. After defining the model that better adapts to the reality of Ceará State, considering simplicity and applicability of each model, the valuation of water as an economic good was performed in the Salgado river basin, in Cariri region. Optimal prices for water supply and domestic sewage was calculated based on the economic theory of general equilibrium, known as second best. The results showed that elasticity of demand, for each purpose of use, is inelastic reinforcing the results of other studies on water charging. The calculated optimal prices were R$ 0,0148/m3 for water supply, and R$ 0,1914/kg DBO for domestic sewage.
