The Federal District is located in an area of ”‹”‹water vulnerability. Recently it faced a period of rationing due to the low availability observed in the sources of public supply of the region. This situation has motivated the search for new water sources, requiring increasingly distant sources and increasing complexity of the water infrastructure to meet these demands (supply management). However, new approaches (management of demand) that prioritize actions of conservation, efficient consumption and use of alternative sources of water in buildings should be required as a complementary, not unique option, to the exploration of new sources or increase the pressure on those already used. In this sense, this article seeks to evaluate the potential of reducing the exploitation of local water resources by the use of rainwater in buildings, by comparing the water balance of the main supply reservoir of the region - Descoberto - in the critical year of 2016, with other simulations considering pre-determined premises of implantation of these systems in large scale in the buildings located in the Administrative Regions supplied by this reservoir. The result points to the strong need for fiscal and economic incentives to increase autonomy and water resilience in the Federal District through the use of rainwater.
