MG, bem como examinar os efeitos das vari?veis determinantes em seu comportamento. Permite ainda uma compreens?o do cen?rio pesquisado, possibilitando, deste modo, analisar a magnitude de poss?veis pol?ticas tarif?rias utilizadas, sendo capaz de sustentar no processo decis?rio sobre a necessidade de investimentos, por meio de proje??es do consumo. Para esse fim, utilizou-se t?cnicas de an?lise explorat?ria temporal de dados, considerando o per?odo de setembro de 2012 a dezembro de 2014, dividida em duas categorias de consumo: social e normal. O modelo de demanda de ?gua apoiou-se na estrutura tarif?ria da Companhia de Saneamento de Minas Gerais (COPASA-MG), visando avaliar aspectos importantes tanto para o servi?o de abastecimento de ?gua quanto de consumidores. Ressalta-se a import?ncia das vari?veis pre?o m?dio, renda e clima, objetivando-se substancialmente em encontrar os par?metros de elasticidade. A compreens?o desses par?metros viabiliza uma an?lise do impacto de pol?ticas tarif?rias e possibilita a proje??o do consumo futuro de ?gua no longo prazo. Os resultados encontrados destacam a inelasticidade pre?o da demanda de ?gua para ambas categorias estudadas, apresentando coeficientes significativos para o pre?o marginal e a vari?vel diferen?a. A quantidade de ?gua defasada e a renda para ambas as categorias estudadas, n?o apresentaram o sinal esperado pela literatura; j? o clima, na categoria normal, o coeficiente n?o foi significativo estatisticamente; e na categoria social, o coeficiente mostrou-se significativo. Portanto, presume-se um maior conhecimento na estrutura tarif?ria da cidade, al?m da busca por vari?veis que expliquem melhor a demanda de ?gua. / Disserta??o (Mestrado Profissional) ?

It also allows an understanding of the researched scenario, thus making it possible to analyze the magnitude of possible tariff policies used, being able to sustain in the decision making process on the need for investments, through consumption projections. For this purpose, we used techniques for exploratory temporal data analysis, considering the period from September 2012 to December 2014, divided into two categories of consumption: social residential and normal residential. The water demand model was based on the tariff structure of the Minas Gerais Sanitation Company (COPASA-MG), in order to evaluate important aspects for both the water supply service and consumers. The significance of the variables average price, income and climate is emphasized, aiming substantially at finding the parameters of elasticity. The understanding of these parameters enables an analysis of the impact of tariff policies and enables the projection of future water consumption in the long term. The results found highlight the price inelasticity of water demand for both categories studied, presenting significant coefficients for the marginal price and the difference variable. The coefficient was not statistically significant, in the social category, the coefficient showed to be highly significant. The coefficient was not statistically significant, in the social category, the coefficient showed to be highly significant. Therefore, it is assumed a greater knowledge in the tariff structure of the city, besides the search for variables that better explain the water demand.
