Water is essential for sustaining life. However, the situations of hydric stress - less than 1.700 m³ per capita water availability per year (FALKENMARK, 1989) - experienced in many parts of the world, coupled with the rapid growth of the global population, the problems related to water use tend to increase. In this context, the water footprint (WF), which is an indicator of environmental sustainability becomes an important tool for water resource management indicates the consumption of fresh water based on their uses. This study aimed to measure the water footprint as a function of industrial components, domestic and feed of the population of the Rocinha s neighborhood, a cluster subnormal located in the municipality of Rio de Janeiro. The research was focused on a case study of 20 sub-districts of the community. Its approach was quantitative, with a sample of 203 households, sampling error of 7% and confidence level of 93%. For this purpose, was used as the tool for calculating the Water Footprint Network model year 2005. The results indicated that, on average, the WF of the individuals in the sample is 1715 m³/ year per capita divided as follows: WF of domestic water consumption of 175 m³/ year per capita (479 l/ inhab.day), WF agricultural products equal to 1470 m³/ year per capita, and WF industrial products 70 m³/ year per capita. The results suggest that individuals in the sample with a higher monthly expenditure tend to have industrial water footprints and overall greater.
