Sistema de aproveitamento de água pluvial para fins não potáveis: um estudo de caso de edificação de serviço público no município de Manaus/AM

Abstract

Urban verticalization and constant population growth in large cities make fresh water a scarce and valuable resource. New constructions emerge with a proactive mindset, incorporating measures to optimize the use of water in the building structure. It aims to promote the sustainable management of water resources through the reuse of water from the system and the capture of rainwater for non-potable uses. This work aims to develop a project that uses rainwater collection for non-potable use in a public service building. Initially, a literature review was carried out on the subject, covering concepts, legislation, advantages and disadvantages of using rainwater. Next, an analysis of the building's characteristics was carried out, such as the roof area and the demand for non-potable water, to define the size of the reservoir and the rainwater treatment system. The project features the installation of a rainwater collection, filtration and storage system, with a capacity of 5,000 liters. The water collected will be used to irrigate gardens, wash floors and flush toilets. In the end, consideration was made regarding the technical feasibility of installing this system in existing buildings.
