ESTUDO DE UM SISTEMA DE CAPTAÇÃO DE ÁGUA DE CHUVA E REUSO DE ÁGUA CINZA PARA FINS NÃO POTÁVEIS PARA O CONDOMÍNIO VILLA ROMANA NO MUNICÍPIO DE VARGINHA - MG

Abstract

This paper presents a case study, conducted in a closed condominium in the city of Varginha - MG, where it was analyzed the waste of water generated by one of the buildings in it. The average discarded volume of gray water (tank and washing machine) and its quality parameters were analyzed. Also calculated were the average annual volumes of rainwater discharged from the roof of the building, which is currently of no use, totaling an average of volumes of water discharged from that building. Thus, a rainwater catchment system and a Gray Water Treatment Plant (ETAC) were proposed, in which its technical and economic viability was evaluated. Where it was found that the proposed system will be able to supply all non-potable water demand to the intended points. But when it comes to savings, its deployment cost does not make it viable due to the high payback period.
