Projeto de reuso de água pluvial em habitação popular para fins não potáveis

Abstract

Strong population growth and urbanization have led to increased drinking water consumption. This factor, coupled with irresponsible use and pollution of water sources, has contributed to a considerable water crisis. Brazil is a privileged country, as it has 12% of the world's freshwater, but due to poor distribution, there are regions of the country where water availability is low, such as the Northeast of Brazil that faces severe scarcity crises most of the year. Therefore, the search for sustainable policies that provide solutions to this problem and at the same time make the population aware of the importance of conscious use of water is necessary. Within this context, the reuse of rainwater becomes a viable alternative, easily applied, which provides the preservation of the environment. Therefore, the present work elaborated a popular housing project in Recife based on the city's Master Plan and designed a Rainwater harvesting System for this dwelling, according to NBR 10844 (1989). In the project, the rainwater was captured only by water from the roof, which enough to meet the house reuse needs, as the city has a high rate of rainfall. The materials used in the installation of the collection system were low cost and simple to apply, where the implementation project presented a much lower cost than the total value of residential construction, besides representing an excellent alternative for environmental awareness and treated water saving
