Designed and manufactured in Brisbane, ASSDA Member Aqseptence Group Australia has recently delivered one of the largest passive intake screens in the Southern Hemisphere. Having produced more than 4,000 screens for the last 50 years, this latest milestone achieved a nomination in the hotly contested Process Industries category of the 2019 ASSDA Fabricator Project of the Year Award.
In mid-August 2019, Aqseptence Group was engaged by a joint venture of John Holland and KBR to provide design and construct services for a significant capital works project, covering multiple Melbourne Water assets. The screen is used as a bulk water transfer screen for the O’Shannassy Dam, located east of Melbourne. Distributing clean drinking water to most parts of Melbourne, it is a critical asset storing 3.1 gigalitres of water among a series of reservoirs on the city’s periphery. The mammoth screen took approximately two months to design and manufacture.
