ESTUDO DE VIABILIDADE TÉCNICA E ECONÔMICA DE IMPLANTAÇÃO DE UM SISTEMA DE APROVEITAMENTO DE ÁGUA DE CHUVA NO BAIRRO SANTA RITA, NO MUNICÍPIO DE MONSENHOR PAULO-MG

Abstract

The viability of rain water use is characterized by decreased water demand provided by water utilities in the case of the city of Monsignor Paul, COPASA, resulting in the reduction of costs with drinking water and reducing the risk of floods in case of heavy or prolonged rains. In the process of rainwater catchment, areas of roofs are used, despising the first rainwater that falls on the roof, because the water has a very high degree of contamination. The rainwater collected by gutters and conductors is stored in reservoirs, the water should be used only for non-potable consumption, such as toilets in garden watering and car washing. This work deals with the study of the technical and economic feasibility of implementation of rainwater utilization system. The viability of the system basically depends on three factors: rainfall, capture and demand area. The rainwater tank is the largest cost component of the system, so it should be designed according to the needs of users and the availability of rainfall in the study area to scales it the right way, without derail the system. Based on the findings can finally conduct the study of the technical and economic feasibility of the system through the return on investment of time. In this study it was possible to evaluate that, for a residence of 3 to 4 people and with an area of 150 m² to 200m², the rainwater utilization project becomes technically and economically feasible.
