SISTEMAS CONSTRUíDOS DE áREAS ALAGADAS: REVIS?O DA LEGISLA??O E DOS PADR?ES DE QUALIDADE DA áGUA

摘要

The shortage of the water has been worrying the world population and the use of this primordial natural resource to the human life, it happens in a growing way. Countries of everyone steer to the development of legal and scientific mechanisms that can control the shortage and to improve the water quality found in the nature. The water quality is theme of a lot of legislations and it won relevance in the last decades. The qualitative and quantitative of water administration is intimately linked to the concept of maintainable development. The right of the future generations is directly linked to the natural resources conservation. The legal norms adapted the new realities and there is need of the implantation of alternative systems of hidric resources conservation. This work sought to detach the pertinent legislations to the hidric resources quality and to compare CWSs to the Brazilian legislation that disposes on the same. After the analysis of the laws and the parameters used to evaluate the efficiency of CWSs the need of adaptation of the same ones was observed the first ones together and of larger amounts of studies than they seek an improvement of that technique.
