The Brazilian Amazon has about 69% of available freshwater in Brazil, an amount which ends up creating the illusion that no lack of water and not lacking in the region, the large supply of this resource becomes a problem when it comes to the Management and Planning Water Resources in the Amazon, according to the wasteful use and lack of maintenance of stocks, compounded by the release of untreated wastewater. Speaking of water conservation programs in the Amazon a few decades ago and still today, with less intensity, is somewhat strange, given the large amount of water available and the culture of abundance. But with climate change associated with the water crisis in the century XXI and the growth of environmental awareness, a new paradigm for water use. Thus, this research discusses the importance of the use of rainwater for non-potable purposes, since the potential for exploitation, throughout the year, due to this high rainfall in the Amazon region, ranging, on average, 119.6 mm in months from November to 441.6 mm in March. It was verified the potential utilization of rainwater from the areas of the roofs of some buildings, located at the Federal University of Pará - UFPA, Campus Guamá, also known as City University Professor José da Silveira Netto. The methods used for sizing of the reservoir were the Rippl and Interactive, and economic viability checking done by the methods of Net Present Value - NPV and discounted payback. As a result, there was obtained by the method of Rippl a volume exceeding 1000 m³, while the interactive method was a maximum of 75 m³. The economic viability presented fragile as a function of time to return exceed the useful life of the utilization system for rain water.

Estudo da vulnerabilidade hídrica das populações que moram na região do Lago da Usina Hidrelétrica de Tucuruí no estado do Pará

The Amazon has a large amount of water resources, and in Brazilian energy policy there is interest in the hydraulic exploitation of this region, for purposes of electric power generation, but these construction cause various social and environmental effects. In the Environmental Impact Studies and in the Environmental Impact Report of hydroelectric dams, the access and use of the water resources of the affected populations are not taken into account. Thus, this thesis aimed to study the water vulnerability of the populations living in the lake region of Tucuruí Hydroelectric Power Plant, in the State of Pará (PA). The question that led to the research hypothesis was: Is water vulnerability a social effect of hydroelectric construction? The analysis was carried out with the support of Social Cartography and Social Impact Assessment, associated with the use of the Institutional Analysis and Development Framework created by Elinor Ostrom, the Qualitative Comparative Analysis method and the fuzzy logic, operationalized by the software fsQCA 2.0. Socioeconomic, institutional and environmental conditions were considered as independent variables (X), in which the precariousness found in these conditions would reflect the water vulnerability that the residents of the Tucuruí hydroelectric dam would be exposed. The results confirmed the hypothesis of this thesis where the construction of the Tucuruí hydroelectric dam caused the water vulnerability of the inhabitants of the lake to a degree of "partially vulnerable" (0,1), and that the socioeconomic, institutional and environmental variables are necessary conditions for explain the phenomenon, however, are only sufficient when analyzed together.
