Este artigo compara eficiências custo de empresas publicas e privadas brasileiras de oferta de água. Para mensurar a eficiência faz-se uso de um modelo de fronteira estocástica definido por meio de uma função custo na família Cobb-Douglas. A especificação da fronteira inclui efeitos técnicos. Estima-se o modelo pelo método de máxima verossimilhança para um painel de firmas brasileiras observadas no período 20022004. Os resultados estatísticos indicam evidência de que as firmas públicas são mais eficientes, embora a diferença em eficiência esteja declinando no período analisado. De um modo geral, o sistema de oferta de água e saneamento está se tornando mais eficiente ao longo do tempo
