ABSTRACT

Esta dissertação analisa as tarifas médias e os custos dos Prestadores Regionais de Água e de Esgoto do Sudeste do Brasil. Foram aplicadas regressões múltiplas a variáveis selecionadas do Sistema Nacional de Informações sobre Saneamento (SNIS), referentes ao ano de 2010. Foi detectado o descolamento entre as tarifas e os custos dos serviços de esgotamento. Em média, as tarifas de esgoto foram identificadas como inferiores às dos serviços de água, apesar de apresentarem custos maiores. Adicionalmente, a diferenciação percebida entre os preços dos serviços de coleta e tratamento de efluentes foi ínfima, o que desincentiva o investimento neste último procedimento, essencial para a saúde da população e para a redução de impactos ambientais...


This dissertation made an evaluation of the average tariff and the cost structure of South-Eastern Brazil’s Water and Sewage Regional Companies (CESBs). Multiple regression models were applied, using Ordinary Least Squares (OLS) in sets of key variables selected from the Brazilian National System of Information in Sanitation (SNIS). The database refers to 2010. A gap was detected between sewage services’ tariffs and costs. On average, sewage tariffs were identified as lower than those of water services, even though their costs were perceived as higher. Additionally, the differentiation between the prices of the collection and the treatment of wastewater services was minimal, which discourages investment in the latter procedure, essential to the population’s health and to reduce environmental impacts...
