Although Brazil has one of the biggest water resources of the Planet, the reuse of greywaters has become necessary, mainly in major urban centres, whose demand is limited by pollution.

O crescimento rápido da população urbana e da industrialização está submetendo a graves pressões os recursos hídricos e a capacidade de proteção ambiental de muitas cidades. Embora o Brasil possua um dos maiores patrimônios hídricos do planeta, o reúso de águas cinzas tem se tornado necessário, principalmente nos grandes centros urbanos, cuja demanda é limitada pela poluição. A construção sustentável procura a interação entre o ser humano e o meio ambiente, provocando considerável diminuição na degradação de ambos. Assim, a possibilidade de substituição de parte da água potável de uma edificação por uma de qualidade inferior para fins não nobres reduz a demanda sobre os mananciais de água. No entanto, cabe institucionalizar, regulamentar e promover o reúso de água no Brasil, fazendo com que essa prática se desenvolva de acordo com princípios técnicos adequados, como também seja economicamente viável. Este trabalho de pesquisa busca determinar os parâmetros de qualidade e quantidade das águas cinzas em edificações, visando à minimização do consumo de água e à sustentabilidade dos recursos hídricos, através do uso racional ou eficiente da água, o qual compreende também o controle de perdas e desperdícios, e o seu reaproveitamento. Este artigo sugere que o reúso da água em edificações é viável, desde que haja projeto para este fim, respeitando-se todas as diretrizes analisadas.

The fast growth of urban population and industrialization has resulted in serious pressures on the water resources and on the capacity of environmental protection in many towns. Although Brazil has one of the biggest water resources of the Planet, the reuse of greywaters has become necessary, mainly in major urban centres, whose demand is limited by pollution. Sustainable construction seeks the interaction between human beings and the environment, resulting in a decrease in the degradation of both. Therefore, the possibility of replacing part of the drinking water used in a building for one of inferior quality, for uses that do not require such a high quality water, may reduce considerable the demand on drinking fountains. However, it is necessary to formalize, regulate and promote water reuse in Brazil, in order to increase the adoption of that practice according to adequate technical principles, and to make it economically feasible. The main objective of this research work is to determine quality parameters and the amount of the greywater in buildings, aiming to minimize the consumption of drinking water and to increase the sustainability of water resources, through the rational or efficient use of the water, which also involves the control of losses and wastes, and its reuse. This article suggests that water reuse in buildings is feasible, provided that the building is designed for that end, considering the analysed guidelines. |
