Reúso de águas no brasil: situação atual e perspectivas

Abstract

This paper discusses the current situation of water reuse in Brazil and presents the perspectives for its use. A discussion is made about the federal and some states' laws, which establish the criteria, procedures and quality standards for the various modalities of reuse, emphasizing that the legal framework at the federal level is still very incipient. It is highlighted that the modalities of industrial and urban reuse were the ones that developed the most in the country, not having news about the use of treated sewage in medium or large systems in irrigation and fish farming. The paper presents the perspectives for the reuse of waters in Brazil, highlighting the proposals for direct or indirect drinking reuse. It is also emphasized the need for a broad program of awareness of the population to face the existing resistance to this practice. The necessary instruments for water reuse in Brazil are discussed, including a legal and institutional framework.
