An energy audit of the pumping systems recommended replacement with more energy-efficient drive units, upgrading the distribution pipework and replacing pumps. Emission savings have been estimated to be 73 t CO2-e per year.

The farm cultivates cotton over a 560 hectare site north-east of Emerald in Central Queensland. Flood irrigation is used, with water being supplied via a common irrigation channel network. Irrigation occurs year-round with 10 irrigation cycles per year, each running continuously for 2.5 or 5 days, depending on the site. The farm uses three pumping stations, two with electric pumps, and the third diesel-powered.
The farm owner is completing a review of the water storage capacities on the farm in conjunction with the review of pump upgrade requirements. Timing for implementation is yet to be confirmed.
