APROVEITAMENTO DE ÁGUA DE CHUVA PARA FINS NÃO POTÁVEIS EM RESIDÊNCIA UNIFAMILIAR EM MUZAMBINHO-MG: Dimensionamento e viabilidade

Abstract

This work addresses the use of rainwater for non-potable purposes in a single-family residence in Muzambinho - MG. Such an approach is justified considering that sustainability in water consumption can help in the preservation of natural resources and in the future of human survival. The objective of this study is to evaluate the implementation of a rainwater harvesting system in a single-family residence, aiming at its dimensioning and the study of its feasibility. This aim was achieved through the literature review and case study. Field research was carried out in Bairro Canaã in a house of 4 inhabitants containing a land area of 353.00m2, a construction area of 164.73m2, with a roof area for the study of 86.40m2. The residence demand is 6,700 l where we reach a reservoir capacity of 20,000 l, that is, 2 boxes of 10,000 the average consumption of drinking water is 16,500 l and the value for implementing the system is R$13,251.07 and for non-potable 6,700 l, with savings of approximately 40%, taking 35 years to return the amount invested.
