PROJETO DE CAPTAÇÃO E APROVEITAMENTO DE ÁGUA PLUVIAL PARA A EDIFICAÇÃO DE UM LAR PARA IDOSOS DA CIDADE DE CARMO DA CACHOEIRA - MG

Abstract

The capture and use of rainwater is, besides a means of financial economy, a saving of drinking 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 construction of Lar São Vicente de Paulo in the city of Carmo da Cachoeira - 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 1,169.58 m² which has the capacity to generate an average monthly volume of approximately 117,850.78 liters of rainwater, and is supply of 28422.6 liters. With the results obtained, it is expressed the viability of the implantation of the system, which will generate a reduction of up to 49.78% in the current drinking water consumption of the building. To fill the months of precipitation deficit, there is a need to have a 17 m³ reservoir and a lifting system 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.
