Water reuse as an alternative to enhance water security in brazil

This study aims to present water reuse as an alternative to enhance water security in Brazil. To achieve this, the main concepts related to the topic were explored, including the types of water reuse, the Brazilian legal and regulatory framework, examples of successful initiatives in the country, and studies on the feasibility of the solution. The findings indicate an increase in the number of laws and regulations on the subject over the past decade, but there is still no national law defining parameters for its use. Additionally, the difficulty in finding information about existing initiatives was observed. The practice has proven to be viable as an alternative source of water supply in various regions, however, further studies on the technical aspects and costs involved are necessary, as well as greater public awareness.
