Sanitation is a fundamental infrastructure service of public health promotion in a community. This article demonstrates the impacts of the lack of sanitation services on its population's health considering the costs involved in Brazil. This study is divided in two segments: 1) analysis of the number of cases by geographic region of the top 10 most expressive waterborne diseases from 2001 to 2010; and 2) comparison between the number of cases of the same diseases with the spending/investments information on health and sanitation according government sources, considering population growth in same period. The results indicate that the number of cases over the years did not suffer a significant setback as expected. This situation can be explained by the lack of adequate investment in sanitation, expressed by poor services in sewage and solid waste treatments, faulty management of urban rainwater and deficient monitoring and maintenance of public water supply installations. The inefficiency of these services directly affects the increase on health spending from waterborne diseases treatments, consequently being an unsatisfactory management model. Therefore, this study affirms the importance of sanitation as a preventive and effective way on the improvement of public health rates in Brazil.

Sendo o saneamento basico um servico de infraestrutura fundamental na promocao da saude publica em uma localidade, este trabalho foi realizado com o objetivo de relacionar os impactos na saude da populacao e os custos gerados, devido a ineficiencia do servico de saneamento ambiental no Brasil. Destacam-se para a elaboracao desse estudo duas etapas: 1) analise do numero de casos, por regiao geografica, de 10 dentre as principais doencas de veiculacao hidrica no periodo de 2001 a 2010; e 2) comparacao entre o numero de casos das mesmas doencas com as informacoes de gastos/investimentos em saude e saneamento e crescimento populacional no mesmo periodo. Pode-se verificar que o numero de casos ao longo dos anos nao sofreu retrocesso significativo, como seria de se esperar. Isso pode ser justificado pela falta de investimentos adequados em saneamento gerando, portanto, uma ma prestacao dos servicos de coleta e tratamento de esgoto sanitario, de gestao de residuos solidos urbanos, de manejo de aguas pluviais urbanas e de abastecimento publico de agua. A ineficiencia destes servicos implica diretamente no aumento dos gastos c
