Abstract
An apparatus for the removal of water from the ground includes a rotatable outer cylinder apertured around its circumference, and a non-rotating part cylindrical member concentric with, and immediately inside the cylinder. The part cylindrical member is open in the region of ground contact. A plurality of sweeper blades are mounted inside the outer cylinder for rotation relative thereto while the outer cylinder is rotating. The blades sweep ground water received through the apertures of the outer cylinder upwardly for trapping between the blades and the part cylindrical member. At a certain height the ground water is discharged into a non-rotating tank inside the outer cylinder.
