A liquid intake assembly includes a filter member having a shower ring for removing solids from the outside surface of the filter member. The shower ring has an annular portion surrounding the filter member and a plurality of nozzle members for directing pressurized fluid in streams adjacent to and generally parallel to the outside surface of the filter member. The streams generate currents in the suspension removing the solids from the outside surface of the filter member.
