Resumen
Due to the limited access to water in an adequate quantity and quality, and the concern with
the environment and its finite resources, the use of rainwater is increasing. This increased use
has contributed to the development of rainwater harvesting systems usage, which is an
alternative capable of minimize the consumption of drinking water that comes from the
conventional system. This study aims to determine the feasibility of implementing the use of
rainwater system for garden watering at Lagoa Nova residential, located in Natal. This system
uses roofing surfaces to catch rain water, which is driven by gutters to storage tanks. Based on
Australian Practical Method, the system efficiencies were analyzed for storage reservoirs with
different capacities. In addition, implementation costs were analyzed with 20, 60 and 120 m³
reservoirs. Based on this, the payback period of the investment was calculated. Studies have shown that even the smallest evaluated reserve (20 m³) is not economically viable, since the
payback period is long. But considering the environmental economy, the system becomes a
good alternative for reducing the use of potable water for non-noble purposes.
