PROBLEM TO BE SOLVED: To provide a pumping water wheel which can attain pumping function even in a small water quantity and at a low water level, can remove refuse and foreign matters by filtering pumped water and realizes extremely smaller number of components and lower manufacturing cost as compared with a conventional one. SOLUTION: The pumping water wheel, which is provided with a sponge which is a hollow assembly formed in a successive saw-tooth shape along the surface of an outer peripheral circle of the water wheel, attains pumping function even in a small water quantity and at a low water level through the utilization of water-absorption property of the sponge and displacement of a shape or the like associated with water wheel rotation.
