Legislações quanto ao reúso de água no Brasil: uma breve fundamentação teórica aliada a óptica de autores da contemporaneidade

Abstract

The attempt in favor of water sustainability has been constantly addressed, in order to minimize the conscious anthropic effects of waste and scarcity. Among several alternatives, the reuse of water is an intelligent path, which in most cases can be adopted in homes and the like. In the past, its poor management may result in a risk to human health, when guidance is not presented to practitioners. With this, the present work aims to present, through contemporary authors, recurring guidelines for the validation of this practice, since, even today, there is no effective regulation at the federal level for the development and implementation of water reuse. The discussion presents applicable categories and maximum establishments of standards for the quality of water reused at the federal and sub-federal levels, however, it is noted that the vast majority systemically guides only water resources, existing a lack in the elaboration of normative exercises that determine the reuse. When presented, it was analyzed that almost always, the values for the quality standard of reuse water are prominent considering the current socioeconomic scenario, which results in the hesitation of the trivial population, both due to lack of technical understanding and the cost factor resulting.
