The Anabranch Pipeline system operates 3 pump stations to maintain consistent supply of water.
River pumps stations are located on the Murray River at Fort Courage, on the Darling River at Polia and are essentially identical systems with three submersible river pumps lifting water to a tank and network pumps which convert filitered water to network pressure. In addition to the river pumps, there is a solar booster pump station halfway along the system at Wyndham which boosts pressure to the top end of the system during the day.
Water is most commonly pumped from Fort Courage, with the Darling River pumps (at Polia) being less frequently utilised due to the lower water levels in the Darling. Prior to the installation of the booster station there were often difficulties maintaining pressure at the highest end of the system, a problem overcome by the installation of the booster pump. Water is boosted to the top of the system during the day during the highest demand, and the river pumps can maintain network pressure overnight when there is typically less demand.
Outlets along the system distribute water to the landholders who have tanks, restrictors, meters, and pressure reduction systems at each property. Calculations for infrastructure were based on total acreage and carrying capacity, with each system designed to be able to be filled from empty within two days. In some instances, water is delivered directly via a pressure reduction valve, but the majority pump into the tanks and then distribute to the paddock from there. Some troughs and paddock tanks were allocated through the establishment phase in order to build resilience across the system.
There are 83 outlets across the system, including 9 irrigation outlets.
