Works continue for major irrigation modernisation upgrades along the Mulwala Canal in NSW.
AWMA have successfully delivered 91 water control gates for Murray Irrigation’s ‘PIIOP Round 3’ which substantially increased water efficiencies, enabled ordering flexibility and significantly reduced leakage through infrastructure upgrades.
These works included 21 Mulwala Canal sites (65 LayFlats and 26 Undershots), Lawson Syphons (two Undershots), the Edward River Escape (two Bulkheads gates) and the Wakool Canal Offtake (three Undershots).
All water control gates were purpose-engineered and manufactured by AWMA to meet exact site and operational requirements. The water control gates were fabricated from 230 tonnes of grade 304 stainless steel, with some components machined from grade 316. The stainless steel water control gates required 7.5km of weld, then pickled to improve corrosion resistance and tested in-house to international ISO 9001 quality standards.
All gates will be connected to the Murray Irrigation SCADA system to be managed remotely, a capability that has radically changed the way water can be delivered to customers.
Mulwala Canal is Australia’s largest irrigation canal. It spans 165km and has the capacity to deliver more than 1,500,000ML of water per year to irrigators in the Southern Riverina helping to generate about $500 million of gross agriculture revenue per year for the region.
Murray Irrigation has up to $114.8 million in funding approved from the Australian Government under Round 3 of its Private Irrigation Infrastructure Operators Program (PIIOP).
Gate solutions for the modernisation program include tilting LayFlat (overshot) gates and ULF (undershot) gates, both proven designs currently operating across many national and international irrigation schemes.
