Estudo da viabilidade econômica de um projeto de captação e uso de água pluvial para uma instituição de ensino na cidade de Ji-Paraná - RO

Abstract

Water is one of the most essential elements for human beings, used for every aspect of the development of a society. Population growth leads to greater demand for drinking water, and water scarcity could become real if there are no changes. Brazil has an abundant amount of water when compared to other countries, however this is not enough if use is irrational. Another obstacle is the heavy rains that often cause flooding. Therefore, there is a need for methods to combat problems like these. As an alternative to these problems, the implementation of a project to capture and use rainwater, through the storage and use of this water for non-potable purposes, which until now has been supplied with treated water, in addition to reducing the possibility of flooding. Likewise, raising people's awareness is also extremely important, and in this case, the application of this type of project in an educational institution is a great example and encouragement for those who will form our society in the future. Following this logic, the main objective of this work is to verify the viability of a system for capturing and using rainwater for non-potable purposes in an educational institution in the city of Ji-Paraná – RO. However, the city's rainfall data was analyzed, following the sizing of the elements using water demand data and the catchment area, in order to proceed with the reservoir sizing method. With all the items defined, we started to carry out the project in AutoCAD software. With the project completed, it was possible to carry out the quantitative and therefore obtain the total cost of the system, concluding with the return time on the investment spent that this system will bring.
