The shortage of water makes this natural resource increasingly relevant for people. Therefore, the population needs to be aware of how to use water rationally and understand the new selective water supply systems. The objective of this study was to implement a rainwater harvesting system based on directing the water collected by roof gutters to a cistern. The system attended satisfactorily the demand for non-potable water for garden watering and washing of household service areas, reducing the use of treated water. The average monthly consumption in 2014 was 21.3 m³ (CI 95% 16.5, 23.8) and in 2015 was 15.7 m³ (CI 95% 13.8, 16.9), showing significant difference between the two years (p= 0.018). The household received a monthly discount bonus for reducing city water consumption. Despite the long term investment payback period, this attitude is an example of citizenship in a city experiencing serious water crisis.
