Abstract: The invention relates to an underground liquid-management system for mines for generating and/or storing energy, for storing and/or cleaning liquids located in the mine, comprising: at least one first store, which is formed by a cavity of the mine, at least one second store, the bottom of which is arranged above the bottom of the first store, at least one line connecting the stores in order to conduct the liquid, at least one pumping device for conveying the liquid through the lines from the first store into the second store, and a geothermal device at least for operating the pump.

Abstract: The present invention relates to a water-storing and water-cleaning system. Said system is designed in such a manner that it can be used irrespective of location. It is used, inter alia, in agriculture, in horticulture and in reforestation. Said system comprises a reservoir (2) that is filled with a porous material (3), into which the water is seeped. In order to displace the seepage path, the reservoir (2) contains at least one barrier layer (5) made of a water-impermeable material, that separates the two layers made of the porous material (3) and comprises an outlet (6) for connecting the layers.
