(57) The invention relates to a method and apparatus for extracting water from water-containing, poorly permeable soil, wherein one or more drainage elements of a water-permeable material are introduced into the soil. A drainage element consisting of a wall (5) of a water-permeable material and of drains (2) of a water-permeable material joining the underside of the wall (5) is formed in the soil. From said wall, water is extracted. A drainage pipe (6) is provided near the underside of said wall (5), which drainage pipe (6) is connected to a pump installation or the like.
