Projeto e dimensionamento de um sistema de captação de água pluvial em um empreendimento de lazer na cidade de Rio Verde, GO

Abstract

Water is an indispensable resource for survival and population growth. Due to disorderly and unsustainable growth in some parts of the world this resource became scarce. In order to mitigate water stress, the water reuse system rainwater shows up as an alternative way to reduce the consumption of drinking water. In that In this work, the use of rainwater for non-potable purposes was evaluated. The research aimed calculate the main devices and the design of a reuse system of rainwater in a commercial enterprise. Using Rippl's method, he calculated the rainwater storage capacity depending on rainfall, catchment area and demand for a commercial enterprise located in Rio Verde-GO. With the flow of project, the gutters, vertical and horizontal conductors and pumping system were calculated for design of the rainwater reuse system. A study was carried out of economic viability considering the budget for the implementation of the system. in the search it is shown that it will take approximately 17 years to recover the initial amount invested considering the savings generated in the water bill charged by the public company. For this project, the cost of implementation considering the lower reservoir of reinforced concrete or polyethylene presented similar values, being viable the construction with the two systems constructive.
