PROJETO DE CAPTAÇÃO E APROVEITAMENTO DE ÁGUA DA CHUVA PARA FINS NÃO POTÁVEIS NA ESCOLA ESTADUAL JOSÉ CRISTIANO ALVES NA CIDADE DE SÃO THOMÉ DAS LETRAS MG

Abstract

This presente work has the objective to collect data and study to the development of a rainwater harvesting project for non - potable use at the José Cristiano Alves School located in the city of São Thomé das Letras - Minas Gerais.The project is justified by the search for alternatives to optimize the use of water resources worldwide. As a public institution, the local becomes appropriate to the installation of the system, since that in these places the consumption and waste tend to be higher. For the project of the system, it was necessary to review the bibliographies, methodologies and applicable norms, to define and characterize the study area, to collect pluviometric data from the region, to size the rainwater storage system for the area, besides the lifting system and cold water distribution system. The present work pursues to design the project so that it works automatically, providing devices for the discard of the first flush, and for the activating and deactivating the lifting system. The study and the sizing demonstrate the technical feasibility and the potential of the implantation of the system in this institution, being able to save on average 122.49 m³ per month of potable water, reducing environmental impacts, the costs with the public supply and relieving the urban system drainage.
