Abstract In the Federal District of Brazil, the groundwater must be taken as a strategic resource once the aquifers are of low capacity of water reservation. Due to this scenario the groundwater may be applied in specific activities including water supply of little communities, industry areas or in service stations. The increase in usage of groundwater, associated to the inadequate occupation of land and watershed result in many problems related to the aquifer exploration. It is necessary to develop management practices to get the sustainability of the system. So that the management processes reach the expected results, the applied techniques must be integrated and related to the filter, regulatory and reservoir functions of the aquifers. Among the actions to be developed the most important are the construction of wells according to the technical norms, definition of the protection perimeters of wells and aquifer recharge areas, improvement in the investments on sanitation, restriction of surface sealing in areas of regional recharge conditions, application of artificial aquifer recharge project, mapping the vulnerability and the contamination risk of the aquifers, development of control systems of the demand outputs and increase the financial resources to scientific study of the groundwater system
Keywords: Groundwater management, fractured aquifers.
Resumo Em função dos tipos de aqüíferos presentes no Distrito Federal e sua limitada capacidade de reservação e circulação, a água subterrânea deve ser utilizada como um recurso estratégico aplicado a setores específicos da economia ou como fonte de abastecimento de pequenos centros urbanos ou núcleos rurais. O contínuo incremento do uso das águas subterrâneas, aliado ao uso e ocupação
