PROJETO DE CAPTAÇÃO E APROVEITAMENTO DE ÁGUA PLUVIAL PARA O LAR SÃO VICENTE DE PAULO

Abstract

The capture and use of rainwater are some alternatives for reducing expenses and environmental impacts, in addition to considerably reducing the consumption of drinking water. Considering the importance of this theme for society, this work aims to analyze the technical and financial feasibility for the implementation of a rainwater collection and use system at Lar São Vicente de Paulo de Carmo da Cachoeira - MG. Theoretical studies were carried out for the development of this project. Subsequently, the data were presented for calculations and analyzes. In the collection of rainwater that falls on the roof, gutters, vertical and horizontal conductors are used and stored in reservoirs of different materials, only being possible to be used for non-potable consumption. The viability of the system depends on precipitation, collection area and demand and the reservoir must be designed according to needs. After the analysis carried out, based on the acquired theory, it was found that the asylum has a catchment area of 916.47 m² that has the capacity to generate an average monthly volume of approximately 91,647 liters of rainwater, and it is possible to supply the demand for 28,422.6 liters. With the results obtained, the feasibility of implementing the system is expressed, which will generate a reduction of up to 43.83% in the current consumption of drinking water in the building.
