PROJETO DE CAPTAÇÃO E APROVEITAMENTO DE ÁGUA DA CHUVA PARA FINS NÃO POTÁVEIS EM UM CONDOMÍNIO RESIDENCIAL MULTIFAMILIAR DA EMPRESA BRZ EMPREENDIMENTOS NA CIDADE DE VARGINHA MG

Abstract

Rainwater harvesting systems are able to reduce drinking water consumption and consequently reduce financial costs, conserve water resources, which contributes to the preservation of the environment and among other factors. Thus, this paper aims to analyze the technical feasibility of implementing a rainwater catchment and utilization system in the condominium Portal Tulipas do Campo, which is a multifamily residential development of the company BRZ Empreendimentos, and is located in the city of Varginha - MG. The theoretical bases for understanding the subject will be presented, as well as the analysis made in the focus area of the study, with data raised through photos, measurements and analysis of the building plans. Based on the analysis performed, it found that the project has a catchment area of 9,351.16 m², which can generate an average monthly volume of 973,484.23 liters of rainwater, and it is possible to meet the demand of 280,723.64 liters. With the obtained results, it is contacted that the implantation of the system is technically viable. In order to meet the months of rainfall deficit, it is necessary to build a storage reservoir with a volume of 250 m³, the establishment of a reservoir at the top of the condominium to distribute the captured water, with a volume of 10 m³, and a system lift responsible for bringing water from the storage reservoir to the distribution reservoir. After all the calculations performed and the design of the rainwater harvesting system it was possible to estimate the cost that would represent the execution of this project
