This paper studies the potential savings of potable water with the implantation of rainwater systems in Brazilian residences in Irati, Paraná. Data on residential roof area were gathered from a satellite image of study area and two methods were used to choose the reservoir size, which consider the percentage increase in saving drinking water and system reliability. The reservoirs were designed considering different roof area ranges, from which one were calculated the water savings that the system would provide. The average savings for potable water, with the implementation of the system, was 44.92%, representing a value of 148.43 m3 per day per householdAttribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/Aproveitamento de água de chuvaSensoriamento remoto de alta resoluçãoDimensionamento de reservatórioarticle10.5777/ambiencia.2011.01.05
