PROJETO DE CAPTAÇÃO E APROVEITAMENTO DE ÁGUA PLUVIAL EM UMA EDIFICAÇÃO HOTELEIRA NA CIDADE DE VARGINHA – MG

Abstract

The capture and use of rainwater is, besides a means of financial savings, a saving of potable water and generation of several environmental benefits. The present work has the purpose of the technical feasibility analysis of the implantation of a system of capture and use of rainwater in the edification of the Class Hotel of the city of Varginha - MG. The theoretical bases for understanding the subject will be presented, as well as the analysis carried out in the local study area, with data collected through photos, measurements and analysis of the building plans. After the analysis, based on the theory acquired, it was verified that the hotel has a catchment area of 1,461.66m² which has the capacity to generate an average monthly volume of approximately 157,403.88 liters of rainwater, and it is possible supply the demand of 75,578.24 liters. With the results obtained, the viability of the system implementation is expressed, which will generate a reduction of 15.61% in the current drinking water consumption of the building. To fill the months of precipitation deficit, there is a need to have a 150 m³ reservoir and a lifting system composed of two pumps, one to supply the lower storage tank and the other to supply the upper distribution tank. After all the calculations and the final design of the rainwater harvesting system, it was possible to estimate the cost of implementing this project.
