Avac Projects

Queensland Rail

The Avac train decanting system was designed for installation in long haul train “stabling” or maintenance yards, in order to provide safe and efficient decanting of raw sewage from regional and interstate trains that are equipped with on-board toilets. More here.


Perth Stadium

With the capacity of the WACA at just 24,500 and Subiaco at 43,500 the West Australian Government wanted to build a higher capacity world class sporting arena. Built on unstable, sandy marshlands, there is an expectation that a building of this magnitude will 'shift' over time. Avac's Vacuum Plumbing solutions was selected for the New Perth Stadium project because our piping network can be fitted above ground, meaning no waste is draining under the slab. More here.



Gravity can give mixed results when it comes to standard drainage. For the MCG Great Southern Stand it was not enough to adequately drain the seating plats, which meant rain and spilled drinks frequently ended up on the heads of people sitting in the lower levels. Avac Australia provided the solution, with a state-of-the-art vacuum drainage system. More here.


The Professor Marie Bashir Centre BioBank

BioBank is a highly specialised secure research facility located in Sydney’s Health precinct in the city’s inner west. Although the facility required a complete refurbishment, the presence of a Mental Health facility in the ground floor of the building meant traditional gravity drainage was impossible for this first-floor facility as access to the celling space on the floor below was unobtainable. More here.


Brisbane Showground

Avac supplied and commissioned a unique vacuum drainage solution for the RNA Showground Industrial Pavilion in Brisbane. The challenge that faced NDY as lead design engineers was to drain an elevated exhibition fl oor with “a 5000 square metre footprint and maintain fall in less than 250mm under the slab.” More here.
