Abstract (en)

The system for storing and purifying water for the horticulture, recultivation of soils and reforestation, comprises a reservoir (2) partly filled with porous material (3), a barrier layer (5) for lengthening the seeping path of the water, and a water collection container, which extends itself from the base of the reservoir up to its surface. The barrier layer is arranged within the water-impermeable, artificial, and outwardly defined reservoir and is provided with a passage (6) for water. The porous material is present itself above and below the barrier layer. The system for storing and purifying water for the horticulture, recultivation of soils and reforestation, comprises a reservoir (2) partly filled with porous material (3), a barrier layer (5) for lengthening the seeping path of the water, and a water collection container, which extends itself from the base of the reservoir up to its surface. The barrier layer is arranged within the water-impermeable, artificial, and outwardly defined reservoir and is provided with a passage (6) for the water. The porous material is present itself above and below the barrier layer. The water collection container comprises an opening (8) above the top barrier layer and below the bottom barrier layer, where the water flows through the opening. The water collection container is connected with a water withdrawal station such as a pumping station over the opening. The barrier layer is horizontally arranged within the reservoir. The passage for water is arranged in the outer area of the barrier layer and is present in form of a slot or a hole. In the two barrier layers, the passages are movably arranged to each other. The reservoir has a tub-shaped or hemispherical shape. The porous material is crushed stone, gravel and/or sand. The water collection container is a well. A planting layer such as humus layer is applied on the porous material above the top barrier layer. The barrier layer and/or the reservoir comprise a geo textile, which comprises a first- and a second layer made of a fabric or a non-woven and polyurethane, which seals holes and spaces in the layer, where the non-woven has spinning fibers with a length of 3-15 cm and wires. The first and second layers are adhered together by the polyurethane and are coated with the polyurethane.

Abstract (de)

Die vorliegende Erfindung betrifft ein wasserspeicherndes und wasserreinigendes System. Dieses System ist derart ausgebildet, dass es ortsunabhängig eingesetzt werden kann. Es findet unter anderem Anwendung in der Landwirtschaft, im Gartenbau und bei der Wiederaufforstung. Das System weist dazu ein mit porösen Material (3) gefülltes Reservoir (2) auf, in dem das Wasser versichert wird. Zur Verlängerung des Sicherweges enthält das Resevoir (2) mindestens eine Barriereschicht (5) aus wasserdurchlässigen Material, das zwei Schichten aus porösem Material (3) trennt und einem Durchlaß (6) zur Verbindung der Schichten aufweist.
