Estudo de viabilidade de aproveitamento de águas pluviais para fins não potáveis em uma residência unifamiliar

Abstract

More and more water resources present in nature are threatened by degradation of watersheds, or the disorderly development of cities along with the population growth, in addition to the environmental pollution. In an attempt to resolve or mitigate this problem some Brazilian cities have adopted laws that require capture and store rainwater in own edification for the flood containment and waste with treated water. This study had as general objective to analyze the feasibility of the use of rainwater for drinking not consumption in single-family residence, in order to reduce water consumption and therefore contribute to the sustainability of water resources in the region with the intensification of the use of rainwater. Through a case study, developed in a medium standard residence, located in the municipality of Ponta Grossa, as well, the potential volume of water to be picked up by the cover of the building through the analysis of rainfall in the region, the area of collection of rainwater and seepage coefficient. It was then the demand for potable and non-potable, as well as the activities that allow the use of rain water. It was the simplicity of the system of harnessing rain water in the buildings, their efficiency and their importance to the environment. So, through this study, it was concluded that the efficient use of water represents a real savings for consumers, businesses and society as a whole and to enjoy the rain water in the buildings means a lot more to reduce consumption and the cost of treated water, represents a crucial development for the construction of a fairer world, in which everyone has access to good quality water.
