a diverter valve positioned within the nozzle turret and configured to intermittently shift between a first valve position
and a second valve position, wherein the diverter valve is configured to permit a first amount of water flow to the first
port when in the first valve position, and wherein the diverter valve is configured to permit a second amount of water flow
less than the first amount of water flow but greater than zero to the first port when in the second valve position;

a gear train reduction capable of rotating the nozzle turret; and
a turbine coupled to an input shaft of the gear train reduction.
