AWMA Debris Screens for the Newry Pipeline intake system use fish-friendly screening technology to ensure debris-free water delivery.
The Southern Rural Water (SRW) Macalister Irrigation District Modernisation Project is focused on replacing the district’s ageing channel irrigation network with a modern system. This project included construction of the $39.8 million Newry Pipeline. AWMA worked in partnership with Jaydo Constructions and SRW to deliver self-cleaning inlet screens for the project.
Cone screens were specified for the inlet structure to ensure the pipeline remains debris-free, protecting downstream infrastructure and delivering reliable flows of high-quality water.
The pipeline inlet structure design included two AWMA Cone Screens as they are suited for shallow water applications, thus ensuring flow intake capacity during low channel levels. The cone screens, designed to deliver flows of 100ML/day, utilise a 2mm aperture wedge wire screen medium, are manufactured from grade 304 stainless steel and benefit from a tri-brush cleaning system. The integrated brush cleaning system is driven by a solar, hydraulic power unit (HPU).
The screen cleaning system has a low-duty cycle, operating for 2 minutes every 8 hours which is controlled through the automated system and monitored via SCADA.
Every AWMA screen solution is engineered to meet specific flow and velocity criteria with a minimal construction footprint. The self-cleaning functionality ensures that reliable, cost-effective and high quality water is delivered. This modern screening technology is durable, compliant with industry best practice, has low whole-of-life costs and is internationally proven.
A set of 5 metre wide AWMA Stopboards with storage racks were also supplied to facilitate isolation, inspection and maintenance of the intake structure and screens. An integrated service platform was installed to ensure operators could safely inspect the screens, brushes and observe operation at any time.
