Whyalla Beef has grown to become one of Australia’s largest, state-of-the-art feedlots. Located in Southern Queensland, Whyalla Beef produces premium grainfed cattle, two of the Group’s Wagyu brands – Wild Rivers Purebred Wagyu and Oakey Premium Wagyu – are all finished at the Whyalla Beef feedlot before moving to the Group’s processing plant-based at Oakey.
A Self Cleaning, Self Propelled Cylinder Fish Screen was installed at Whyalla Feedlot, Texas by Texas Pumps and Irrigation in 2022. The screen is driven via an internal propeller that rotates as water is pumped through the suction line. There are no external power requirements necessary to operate the screen. Internal and external brushes ensure that the screen remains clean, and any entrained debris is returned to the river. The screen is suitable for flows up to 12 ML/day based on approach velocity of 0.12 m/s.
Features of the Installed Fish Screen
• One AWMA-manufactured fish screen was fitted to the current irrigation system.
• The screen is self-cleaning, driven via an internal propeller that rotates as water is pumped through the suction line.
• Internal and external brushes ensure that the screen remains clean, and any entrained debris is returned to the river.
Why This Matters
- Protects native fish populations by keeping them in the river where they belong.
- Prevents debris from entering the pump, improving efficiency.
- Simplifies maintenance, even during high river levels or floods.
