Apparatus for removing water from the ground

An apparatus for the removal of water from the ground, including a ground engaging drum comprising an outer hollow cylinder mounted for rotation about a horizontal axis, a plurality of apertures distributed around the circumference of the outer cylinder, a non-rotating part cylindrical member concentric with and mounted immediately inside the outer cylinder, the part cylindrical member being open in the region of ground contact of the drum to permit receipt of ground water through the apertures in the outer cylinder, a plurality of elements disposed within the outer cylinder and mounted for rotation concentric therewith, means for effecting rotation of the said plurality of elements relative to the outer cylinder during rotation of the latter, the said elements engaging the inside surface of the outer cylinder and the part cylindrical member in such manner as to sweep ground water received through the apertures upwardly away from the ground for trapping between the said elements and the part cylindrical member, and a non-rotating water tank mounted within the outer cylinder into which water swept upwards by the said elements is discharged at a certain height.
