Abstract
A method of circulating ground water in a ground region with a fall of a ground water level, comprises the steps of forming a first well shaft with a water permeable shaft wall in a ground region through which ground water flows, forming at least one second well shaft with a water permeable shaft wall at a distance from the first shaft wall in a ground region with a lower ground water level than in the first well shaft, providing a transverse connection between the first well shaft and the at least one second well shaft so that the ground water can flow from the first well shaft under the action of a ground water level fall into the at least one second well shaft.
