Resumo: | The use of rainwater has become a crucial topic in ensuring the sustainability of water resources and improving sanitary conditions in specific locations. This study aims to evaluate the influence of metal and fiber-cement roof coatings on the quality of rainwater obtained from rainwater harvesting systems in Rio de Janeiro. Fifty-seven samples of stored rainwater were collected and analyzed from first-flush (FF) and reservoir (RR) points between 2017 and 2019, complying with NBR 15.527/2019 and NBR 16.783/2019 standards for residual chlorine, total and thermotolerant coliforms, conductivity, dissolved organic carbon (COD), pH, and turbidity parameters. Descriptive statistics using Excel and R Studio were employed for water quality assessment. The fiber-cement roof exhibited alkaline pH levels, while the metal roof showed higher turbidity values. The COD parameter did not comply with NBR 16.783/2019 in both systems. Nevertheless, both metal and fiber-cement roofs met the primary limits established by NBR 15.527/2019, thus serving as a source of non-potable use of rainwater. |

Este estudio tiene como objetivo evaluar la influencia de revestimientos de techos metálicos y de fibrocemento en la calidad del agua pluvial obtenida de sistemas de captación y almacenamiento de agua de lluvia en Río de Janeiro. Se recolectaron y analizaron 57 muestras de agua de lluvia almacenada en los puntos de primer lavado (FF) y en el depósito (RR) entre 2017 y 2019, cumpliendo con las normas NBR 15.527/2019 y NBR 16.783/2019 en relación a los parámetros de cloro residual, coliformes totales y termotolerantes, conductividad, carbono orgánico disuelto (COD), pH y turbidez. La metodología utilizada para evaluar la calidad del agua de lluvia fue la estadística descriptiva con los programas Excel y R Studio. El techo de fibrocemento presentó resultados de pH con un contenido alcalino, mientras que el techo metálico mostró valores más altos de turbidez. El parámetro COD no cumplió con la norma NBR 16.783/2019 en ambos sistemas. Sin embargo, tanto los techos metálicos como los de fibrocemento cumplieron con los límites establecidos por la norma NBR 15.527/2019, sirviendo así como fuente de uso no potable de agua de lluvia.O aproveitamento das águas da chuva tem se tornado um tema fundamental, no sentido de garantir a sustentabilidade dos recursos hídricos e a melhoria de condições sanitárias em determinadas localidades. Este trabalho visa avaliar a influência de revestimentos de telhados metálicos e de fibrocimento na qualidade de águas pluviais obtidas de sistemas de captação e armazenamento de água pluvial, no Rio de Janeiro. Foram coletadas e analisadas 57 amostras de volumes armazenados de água de chuva nos pontos first-flush (FF) e reservatório (RR), entre 2017 e 2019, em atendimento à NBR 15.527/2019 e NBR 16.783/2019, dos parâmetros: cloro residual, coliformes totais e termotolerantes, condutividade, carbono orgânico dissolvido (COD), pH e turbidez. A metodologia utilizada para a avaliação da qualidade das águas pluviais foi a estatística descritiva com os programas Excel e R Studio. O telhado de fibrocimento apresentou resultados de pH com um teor alcalino, enquanto o telhado metálico apresentou valores maiores de turbidez. O parâmetro COD não atendeu a NBR 16.783/2019 em ambos os sistemas. Ainda assim, os telhados metálico e de fibrocimento atenderam aos principais limites estabelecidos pela NBR 15.527/2019, de modo atender como fonte de uso não potável da água da chuva.Programa de Pós-graduação em Arquitetura e Urbanismo, Faculdade de Arquitetura e Urbanismo2023-08-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo avaliado pelos paresapplication/pdfapplication/pdfhttps://periodicos.unb.br/index.php/paranoa/article/view/4728110.18830/issn.1679-0944.n34.2023.16Paranoá; Vol. 16 No. 34 (2023): January/June Edition; 1-24Paranoá; v. 16 n. 34 (2023): Fluxo Contínuo - Janeiro/Junho; 1-241679-09441677-7395reponame:P@ranoáinstname:Universidade de Brasília (UnB)instacron:UNBporhttps://periodicos.unb.br/index.php/paranoa/article/view/47281/38376https://periodicos.unb.br/index.php/paranoa/article/view/47281/38377Copyright (c) 2023 Paranoáhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDelduque Alves, LeticiaMoreira de Souza, CarolineCosta Areas de Almeida, JaquelineAlmeida de Souza, Ana BeatrizCristina de Andrade, RosaneTorres Netto, AlenaAkira Ohnuma Jr, Alfredo2024-02-08T15:00:47Zoai:ojs.pkp.sfu.ca:article/47281Revistahttps://periodicos.unb.br/index.php/paranoaPUBhttps://periodicos.unb.br/index.php/paranoa/oaiparanoa@unb.br1679-09441677-7395opendoar:2024-02-08T15:00:47P@ranoá - Universidade de Brasília (UnB)false |
