Proposta de um sistema de aproveitamento de águas pluviais no semiárido cearense: estudo de caso na Universidade Federal do Ceará em Crateús

Abstract

Educational institutions have great potential for the implementation of building systems for the use of rainwater due to their willingness to a vast area for capture. In this context, the university is part of the important role of guiding society through sustainable paths. Thus, the objective of this work was to propose a system of use of rainwater coverage for non-drinking purposes in two buildings of the Federal University of Ceará, Campus Crateús. Therefore, we sought to contextualize and synthesize some aspects related to water conservation, the organization and components of the rainwater use system, emphasizing the seriousness with which the theme should be addressed. Based on the survey of local rainfall data, in addition to information such as demand for non-drinking water, an investigation was carried out on the potential for the capture and use of rainwater if the system were implemented. The research verified the conditions of the existing structure as well as the sizing of system components. The results indicated that rainwater harvesting would provide a significant savings in drinking water spending, which could generate a reduction in consumption in order 70%, supplying all demand for sanitary, urinal basins, cleaning activity and irrigation.
