A liquid flow distribution system comprises a flow chamber and a rotor. The flow chamber has a flow chamber inlet, a flow chamber outlet and a chamber flow path extending from the flow chamber inlet to the flow chamber outlet. The flow chamber path is curved so as to generate a generally vortical flow in liquid passing through the chamber flow path. The rotor has a plurality of rotor blades rotatably mounted about a rotor axis. The rotor is mounted in proximity to the flow chamber outlet and positioned such that a flow of liquid exiting the flow chamber outlet impacts one or more of the rotor blades to rotationally drive the rotor. Rotational driving of the rotor in turn disperses liquid impacting the rotor blades.
