Dispositivos poupadores de água em um ambiente universitário: análise da viabilidade

Abstract

In view of the growing scarcity of water in urban centers, and because it is a limited and indispensable natural resource for life, care should be taken to preserve it and thus be essential for its conservation. The present study aims to evaluate the use of water-saving equipment in the main building of Campus Sertão UFAL, in Delmiro Gouveia, Alagoas. At the outset, data collection on time, frequency and consumption of the Campus and measurements of the flow of lavatory taps were carried out. These surveys allowed us to estimate the final use of the water from the lavatory faucets for the current situation. Subsequently, scenarios were created for different saving devices and the differences in water consumption were obtained. For the cases created, an economic feasibility analysis of the implementation was carried out, taking into account the cost of implementation along with the discounted payback. Through this study, economically viable situations were shown, with an investment return time of five months. With the implementation of a water-saving system at Campus Sertão - UFAL, a short period was observed for the return on investment, generating water savings in the lavatory faucets of approximately 42%.
