Potencial de aproveitamento de água de chuva na Universidade Federal do Pará - Belém/PA

The objective of this article is to evaluate the potential of rainwater harvesting in the Federal University of Para (UFPA), as well as the potable water savings by using rainwater, contributing to the management and sustainable resource planning water in the region. For this, the areas of the buildings of Basic and Professional Sector of university were raised. A time series of rainfall with 46 years of observations to the city of Belem was used. Water consumption in the two colletive bathrooms was monitored and was estimated in other buildings. The results show that due to high rainfall and large catchment areas, the UFPa has a real and positive potential for rainwater utilization as an alternative supply, since it was found that in the rainy season economics drinking water by rainwater use presented percentages greater than 100%, which demonstrates a great alternative to water savings provided by the university's supply system.
