Resumo:
The water footprint is defined as the total volume of water used during production and consumption of goods and services, as well as direct and indirect consumption in the production. The use of water occurs mostly in agricultural production, highlighting a significant quantity of water consumed and polluted, derived from industrial and domestic sectors. Therefore, achieve the water footprint is to make possible the quantification of the total water consumption throughout its supply chain. Thus, the main goal of this work is to present a tool for estimating the water footprint to the Brazilians families taking into consideration Brazil's consumption habits. It was developed a software, Calculadora da Pegada Hídrica Residencial (HIDROCALC) wich are available several categories of consumption calculation. The efficiency of the program was evaluated comparing it to calculators developed worldwide, as well as the world calculator of the Water Footprint Network (WFN). The results indicate that the HIDROCALC provides reliable and continuous results to estimates residential water footprint scale on daily, monthly or yearly consumption.
