Aproveitamento de águas pluviais para fins não potáveis: estudo de caso para uma residência em Rio Brilhante – MS

Abstract

Brazil holds about 12% of the world's fresh water, however, the increasing demand and consumption by agricultural and industrial activities creates problems such as pollution and decreasing supply. In order to mitigate these problems, rainwater and greywater catchment and reuse systems have been developed. The objective of this study is to present the sizing of a rainwater harvesting system for non-potable purposes, using as a case study a residence in the city of Rio Brilhante - MS. The methodology used is based on NBR 15527/2019, using the method proposed in the standard for pre-dimensioning and subsequent optimization in software Netuno®, suitable for reservoirs with commercial dimensions. The results are satisfactory, since the reservoirs capacity was determined, as well as the system sizing for its implementation, meeting the recommendations of Brazilian technical standards and design manuals for rainwater reuse systems.
