Proposta de aproveitamento de água pluvial para o prédio da Secretaria de Tecnologia da Informação da Universidade Federal do Ceará

Abstract

Water is a priceless natural resource because It is indispensable for a multitude of activities and processes. The global water scenario is becoming increasingly worrying as the availability of adequate drinking water is decreasing. Rainwater thus presents itself as a strategic resource in the perspective of sustainable consumption. The present dissertation presents a proposal of rainwater utilization for the building of the Information Technology Secretariat (STI) of the Federal University of Ceará (UFC). The intention is to measure the benefit generated by adoption the system by estimating the potential volume of water storage in the rain, considering the disposal of the first millimeter at the beginning of the rainy season caused by the effect of the first flush. For this purpose, it is based on the recommendations of NBR 10844 and NBR 15527 (ABNT), Voronoi polygons were built to identify which station has the biggest rainfall relative to the project area.Furthermore, the rational use of equations available in the literature, such as Manning equations for free vehicles, from Fortaleza IDF proposed by Silva et al (2013), the Rational Method for Leak Calculation, a Rainwater Reservoir Sizing Method de Azevedo Neto and the English Practical Method. Also, an aim to improve the quality of stored water has been adopted for the DesviUFPE system or mechanism (Lima, 2012), which is responsible for automatically diverting first waters. Following the approach methodology, a potential annual collection volume of 1406.8785 m³ of water was estimated for STI coverage.
