Summary

Two stages were removed from a seven-stage pump which reduced the flow rate but improved the combined efficiency by 25%.  The pump demand has been reduced by 12kW and even with increased running time, running costs have reduced by $1,200 per year with a payback period under two years. Added benefits include emission reductions of 5.4 t CO2-e.

Farm Profile

The farm located in southern Queensland produces cotton utilising flood irrigation beginning with pre-watering in September / October and crop irrigation during January and February. An audit of energy consumption assessed a bore pump that is used for irrigating 27Ha of the farm, from a depth of 50 metres into a head ditch for distribution to the crops.
