Reúso de água: proposta normativa para implementação de política para fins não potáveis no Estado do Rio de Janeiro

Abstract

In the current scenario of intensification of climate and non-climate stressors on water security, especially in large urban conglomerates, it is essential for managers and users of water resources to analyze and develop alternative sources of supply, in addition to traditional water infrastructure. In this context, the option of reuse arises as an alternative water source with great potential in the country, especially to increase water security in metropolitain areas. Based on the finding that the State of Rio de Janeiro has a need for a policy and regulation on the theme, this study has as a main objective to propose a normative text that aims to institute a state policy of water reuse for non-potable purposes. The research was developed using methods of bibliographic review, document survey, panel of experts and observation research. The state of art was identified on the existing legislation and legal proposals on the subject in Brazil, no policy or regulation, to which comments were made, in order to extract concepts and minimum content for the normative proposal of this studty. The main result is thus a draft decree on the water reuse for non-drinking purposes in the State of Rio de Janeiro. As a recommendation for effective implementation of reuse practices, the study also highlights the need to issue technical rules to be dispatched by the environmental agency to regulate the modalities of reuse.
