Abstract
A lift station and method for lifting liquid and chips flowing in a shallow stream trough to a higher level for further handling by rotation of a bladed wheel in a housing arranged to receive the liquid flow stream. The rotating blades cause the liquid to be swept up a forward housing wall and to be slung off the blades into an upwardly and backwardly extending exit chute, having sufficient momentum to reach and pass over a weir edge at the upper end of the chute, the liquid then directed into a collection tank where it may accumulate to a much greater depth than the depth of the flow stream.
