The objective of this study was to evaluate the potential for reuse of treated gray water (TGW) in a high standard residence in Feira de Santana ? BA. The microbiological risk for TGW use was assessed via the methodology Quantitative Microbial Risk Assessment (QMRA); the potential for generating bad odors by means of pH, DO and ORP measurements; the color was measured directly; and the embodied energy using the methodology of Life Cicle Assessment LCA. The average microbiological risk of TWG was of the order of 10-5 DALY.pppa-1. The ACT also presented ow potential for generating bad odors. The measured color was on average 13.5HU, with a standard deviation of 10 uH. The system?s embodied energy found was 2.74 kWh/m? of TGW produced, lower than the local concessionaire numbers. The gray water (GW) is found to have great potential for less noble reuse purposes / O tratamento e o re?so de ?guas cinzas tem sido estudado como uma alternativa para usos n?o pot?veis. O objetivo deste trabalho foi avaliar o potencial de re?so de ?gua cinza tratada (ACT) em uma resid?ncia de alto padr?o em Feira de Santana ? BA. Analisou-se o risco microbiol?gico atrav?s da metodologia da Avalia??o Quantitativa de Risco Microbiol?gico (AQRM); o potencial de gera??o de maus odores por meio de pH, OD e ORP; a cor medida diretamente; e a energia incorporada usando a metodologia da An?lise do Ciclo de Vida (ACV). A m?dia do risco microbiol?gico da ACT foi da ordem de 10-5 DALY.pppa-1. A ACT tamb?m monstrou baixo potencial em gerar maus odores. A cor medida foi em m?dia 13,5 uH, com desvio padr?o de 10 uH. A intensidade energ?tica do sistema foi de 2,74 kWh/m? de ACT produzida, resultado inferior ao da concession?ria local. Conclui-se que a ?gua cinza (AC) possui grande potencial de re?so para fins menos nobres
