Avaliação da qualidade de águas de chuva armazenadas em cisternas de placas e de polietileno em um município do semiárido do estado da Paraíba

Abstract: RESUMO Neste trabalho é apresentada uma avaliação das águas de chuva armazenadas em cisternas no semiárido do estado da Paraíba. Foram coletadas e analisadas amostras de água de cisternas de placas de concreto (CPLA) e de polietileno (CPOL), buscando-se verificar se há diferenças entre os parâmetros de qualidade da água nos dois tipos de cisternas. Foram aplicados testes estatísticos para detectar se há diferenças entre os parâmetros físico-químicos pH, temperatura, turbidez, condutividade elétrica, sólidos to… Show more

“…Even considering that many cistern users utilize stored water for potable uses (Doss-Gollin et al, 2016), we chose to simulate the use of RWH systems for non-potable uses since there is uncertainty regarding the quality of the water stored if it is not properly preserved (Farto & Silva, 2020;Machado et al, 2021).…”

“…In Brazil, of the three planning scales (national, state, and municipal), it is up to states and municipalities to draw up regulations that help disseminate these technologies to favor water supply (Libanio, 2014; Agência Nacional de Águas e Saneamento Básico, 2020a). Legislation in this regard is still poorly enforced, and due to the need for controlling the quality of the water stored in tanks (Farto & Silva, 2020;Machado et al, 2021), the use of this resource for nonpotable purposes is generally recommended. An example of the efforts to make RWH viable for non-potable uses occurred with the dissemination of the NBR 15527 (Associação Brasileira de Normas Técnicas, 2019), which presents requirements for projects that aim to include this alternative source of water.…”
