Lagos de mina: alternativa para abastecimento público?

Abstract

Localized and non-standard climate events that promote long periods of drought can lead to impact water crises in saturated water supply systems or close to operating limits. The need for sustainable long-term projects is imminent, but emergency solutions are needed to overcome these periods. Cities where mining activity is active can expect at the end of their operations the formation of atypical scenarios in their landscape, such as end-pit mines resulting from the removal of ore. These basins may have noble destinations for society if the groundwater surface is outcropped, not only as a landscape function, since they concentrate considerable volumes of water. The lakes formed mines can offer the possibility of abstraction of water for potability in periods of water crises. This work presents significant volumes in the mathematical modeling of water bodies, estimated by the level of the groundwater table obtained by deep tubular wells, in the metropolitan region of São Paulo, in current and possible scenarios of active or finished mining.
