description A rotatable self-cleaning drum shaped filter is partially submerged in a source of water and encloses the inlet of a conduit connected to a ditch pump. A part of the flow of water drawn through the conduit by the ditch pump rotates a water turbine, which turbine is mechanically connected to the drum shaped filter to rotate the drum shaped filter about its longitudinal axis. Simultaneously, a plurality of stationary nozzles forcibly spray a filtering element of the drum shaped filter as the filtering element rotates therepast to remove debris from the filtering element and prevent clogging of the drum shaped filter and water starvation at the inlet to the conduit.
