Aplicação dos instrumentos de gestão de recursos hídricos “outorga” e “enquadramento” para o setor de saneamento no perímetro urbano da bacia do rio Coxipó – Cuiabá/MT

Abstract

The granting of right of use of water resources aims to ensure the quantitative and qualitative control of water use and the effective exercise of rights of access to water, so essential to the administration of water supply and compatibility of different uses. However, as the granting of right of use of water resources must comply with the framework of water resources in rivers and streams with water availability already saturated for dilution of effluent and / or real quality at odds with the class in which it is framed, it may be necessary to amend the class framework. This work is guided in order to evaluate the uses and impacts in the application of "granting of right of use of water resources" and "transitional framework" for the sanitation sector in the urban river basin Coxipó in Cuiabá/MT. To achieve this, initially it was necessary to make a diagnosis of the current quality of the study area, through literature search covering studies in the area, results of environmental monitoring and field visit. Sequentially, from the use of spreadsheet, and with the knowledge of the demand for water use obtained from the manager of water resources, it was possible to determine the corresponding class water quality of water bodies included in the basin and more preponderant use restrictive in its urban area of Cuiabá. The end result of this work was to formulate a proposal for a transitional framework Coxipó stretches of the river, to allow the regularization of the use for public sanitation. The transitional framework enables the regularization of users, and may result in improvement of water quality parameters of the study area in the medium and long term. This experience can also bring assistance to other municipalities in the state, already suffering from environmental degradation of urban water bodies and have little willingness to dilute its effluents.
