Resumo: | Rainwater harvesting (RWH) is an alternative to the problem of water scarcity. However, its quality must be analyzed before its use, so that it does not represent any danger to the consumer. Thus, the objective of this paper was to analyze the spatial-temporal variation of water quality of rainwater in two cities and observe whether its parameters meet the norm related to the subject. In addition, the concentration of total suspended solids (TSS) that flow into the drainage system was also simulated. Rainwater samples were collected at several points in Congonhas and Ouro Branco - MG, over a period of two years. The results showed that there was spatial-temporal variation in water quality. There were points where the quality met the standard in some moments and did not meet in others, due to its temporal variation. It was also observed that the catchment surface influenced the quality of rainwater, so that the water that came into contact with the roof had its quality deteriorated, at first. However, throughout the rainy event, the quality improved, but at certain times, it was not enough to meet the standard. The rainwater quality simulation, carried out at SWMM, showed high concentrations of TSS, which were higher to that allowed for launching into receiving bodies. |

Sin embargo, su calidad debe ser analizada antes de su uso, para que no represente ningún peligro para el consumidor. Así, el objetivo de este trabajo fue analizar la variación espacio-temporal en la calidad del agua de lluvia en dos ciudades y observar si sus parámetros cumplen con la norma relacionada con el tema. Además, también se simuló la concentración de sólidos suspendidos totales (SST) que fluyen hacia el sistema de drenaje. Se recolectaron muestras de agua de lluvia en varios puntos de Congonhas y Ouro Branco - MG, durante un período de dos años. Los resultados mostraron que hubo una variación espacio-temporal en la calidad del agua. Hubo puntos donde la calidad cumplió con el estándar en algunos momentos y no cumplió en otros, debido a su variación temporal. También se observó que la superficie de captación influyó en la calidad del agua de lluvia, por lo que el agua que entró en contacto con el techo empeoró su calidad, en un principio. Sin embargo, durante todo el evento lluvioso, la calidad mejoró, pero en ciertos momentos, no fue suficiente para cumplir con el estándar. La simulación de la calidad del agua de lluvia, realizada en SWMM, mostró altas concentraciones de SST, las cuales fueron superiores a las permitidas para su lanzamiento a los cuerpos receptores.A captação da água pluvial (CAP) é uma alternativa ao problema de escassez hídrica. Porém, sua a qualidade deve ser analisada antes do seu uso, para que não represente nenhum perigo ao consumidor. Assim, o objetivo deste trabalho foi analisar a variação espaço-temporal da qualidade da água pluvial em duas cidades e observar se os seus parâmetros atendem à norma referente ao assunto. Além disso, também foi simulada a concentração de sólidos suspensos totais (SST) que escoam no sistema de drenagem. Foram coletas amostras de águas pluviais em diversos pontos de Congonhas e Ouro Branco - MG, em um período de dois anos. Os resultados mostraram que ocorreu variação espaço-temporal da qualidade da água. Houve pontos em que a qualidade atendeu a norma em alguns momentos e não atendeu em outros, por conta da sua variação temporal. Também foi observado que a superfície de captação influenciou na qualidade da água pluvial, de forma que as águas que entraram em contato com o telhado tiveram sua qualidade piorada, em um primeiro momento. Porém, ao longo do evento chuvoso, a qualidade melhorou, mas, em determinados momentos, não foi o suficiente para atender à norma. A simulação da qualidade da água pluvial, realizada no SWMM, apresentou concentrações elevadas de SST, as quais foram superiores ao permitido para o lançamento em corpos receptores.Research, Society and Development2021-03-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1359810.33448/rsd-v10i3.13598Research, Society and Development; Vol. 10 No. 3; e45810313598Research, Society and Development; Vol. 10 Núm. 3; e45810313598Research, Society and Development; v. 10 n. 3; e458103135982525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/13598/12176Copyright (c) 2021 Emmanuel Kennedy da Costa Teixeira; Letícia Gabriela Andrade Policarpo; Suely Riciati da Silva; Eliane Prado Cunha Costa dos Santoshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessTeixeira, Emmanuel Kennedy da CostaPolicarpo, Letícia Gabriela AndradeSilva, Suely Riciati da Santos, Eliane Prado Cunha Costa dos 2021-03-28T12:03:35Zoai:ojs.pkp.sfu.ca:article/13598Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:54.097580Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
