PROJETO DE CAPTAÇÃO E APROVEITAMENTO DE ÁGUA PLUVIAL PARA FINS NÃO POTÁVEIS PARA A ESCOLA MUNICIPAL CARROSSEL - ELÓI MENDES – MG

Abstract

The constant population growth and the inadequate use of drinking water have created a scarcity of this resource in several Brazilian regions. Faced with this scenario that directly affects everyone, conscious use is increasingly necessary. And one of the ways to avoid an intense reduction in the availability of drinking water is to make use of rainwater. This use is the capture of rainwater through impermeable areas, which is conducted by means of gutters and conductors, and allows a reserve of water of excellent quality that can be used in activities that do not require drinking water as cleaning of environments . Therefore, this work has as main objective the development of a project to collect and use rainwater for non-potable purposes for the Municipal School Carrossel which is located in the municipality of Elói Mendes. In the diagnosis made through visits to the school, the existence of gutters, vertical and horizontal conductors was identified, and for these devices to be used in the rainwater recovery system, due checks were carried out for each existing device. Analyzing the values of monthly water consumption in the building with the activities of hygiene and sanitary flushes, in addition to determining the possible volume of rainwater according to the coverage area and rainfall index, the bottom reservoir was dimensioned by the Rippl method. However, initially a demand was foreseen that needed a lower reservoir that had dimensions that made its installation unworkable, before that it was resized, where the demand was reduced. In addition, the elevating system, upper reservoir and cold water piping were designed to supply the points of use. Finally, a cost estimate was carried out that would represent the execution of the project, in addition to identifying a return period of 16 years, thus being considered financially unfeasible, however with great socio-environmental impact, due to the fact of providing water awareness.
