DIMENSIONAMENTO E VIABILIDADE DE UM SISTEMA DE APROVEITAMENTO DA ÁGUA PLUVIAL PARA UMA RESIDÊNCIA UNIFAMILIAR EM VARGINHA-MG

Abstract

Due to disordered use, water waste and continuous global pollution, the world has been suffering from water scarcity. With this, the capture and use of rainwater has become an increasingly viable option and most of the time sustainable and economical. This research has the objective of dimensioning the project for capturing and using rainwater and verifying whether the system is economically viable for a medium standard residence with four residents located in the city of Varginha / MG, and in how long the investment pay. After all the predicted calculations and dimensions, the project's feasibility study was carried out, which took into account the budget of the materials to be used, and the savings generated. The savings that this practice provided was approximately 60% in monthly consumption, an average value of R $ 180.00 per month less than what was paid before the system was implemented. However, it is concluded that the implementation of the system is feasible and that it generates good savings in the consumption of drinking water, the payback time is approximately 5 years.
