The paper aims at identifying the main determinants of the presence of water supply and sanitation services, for Brazilian urban households in 2000. The supply and demand dimensions were converted in variables, using data from IBGE and Receita Federal. Descriptive and analytical statistics were performed, in the last case through multiple regression with hierarchical model. In explaining the presence of the services in the households, the supply perspective showed more relevant than the demand variables, probably due to the extreme regional differentials in the Country. In supply dimension the categories that presented the highest chances were the Southeast region and the Autarchic management model. About the demand perspective, the lowest chances are in households were the head are man, single, younger, black and with lower schooling, as well as the family gains are lower.
