Proposta de implantação de um sistema de aproveitamento de água da chuva na UTFPR Campus Pato Branco - Paraná

Abstract

This work has the objective of presenting a rainwater system implementation proposal at the Federal Technological University of Paraná - UTFPR, Pato Branco Campus, in order to reuse the rainwater in toilets. Data were collected in 26 blocks of the Campus, referring to toilet amount and rainwater catchment area. Based on these data, it was possible to calculate the Campus rainwater supply, using the rational method presented by Tomaz (2010). For the estimated Campus water consumption calculation in toilets, data were used regarding its total consumption, as well as parameters presented by Tomaz (2000) to estimate water consumption in toilets, which did not correspond to reality, since the toilets consumption was higher than the total Campus consumption. As the criterion used to calculate the water demand in toilets was inadequate for this study, a new criteria research was necessary. For the new calculation, the estimation of how many times each person uses the toilet, the discharge volume and the discharge activation time were used as criteria, allowing to estimate the amount of water consumed in toilets and the reduction of approximately 350m³ of water and the average saving of R$ 2394,00 per month.
