ESTUDO DE CASO: PROJETO DE APROVEITAMENTO DE ÁGUA PLUVIAL PARA A ESCOLA MUNICIPAL NOSSA SENHORA APARECIDA NO MUNICÍPIO DE TRÊS PONTAS-MG

Abstract

Rainwater harvesting systems are tools with a high capacity to mitigate floods, combat water shortages and reduce financial expenses, and contribute significantly to the preservation of the environment.The present work aims to present a rainwater harvesting project for the Nossa Senhora Aparecida Municipal School, located in the rural area of the city of Três Pontas-MG, and intended for the discharge of the basin and washing the courtyards. It was necessary to establish parameters according to regulatory norms and bibliographical research, in order to obtain theoretical knowledge for its construction. Subsequently determined the flows and demands of rainwater that will be used in the project. It was necessary to obtain data referring to historical rainfall series to allow the characterization of the region's rainfall regime, to diagnose the building's dimensions, coverage dimensions and determination of the number of users. After obtaining all the necessary data, it was possible to calculate rainfall intensity, coverage area, project flow, estimate non-potable water consumption, gutters, vertical conductors, horizontal conductors, the amount of rainwater to be used, lower reservoirs and upper reservoir, the lifting system, the distribution network. Thus, after carrying out the project, its estimated cost was prepared, which resulted in a proposal of R$ $ 52.938,37 for implementation.
