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

The Avac vacuum system at the new Perth Stadium went live in March. Whilst the project is still currently under construction the system is pulling waste water from some commissioned areas in addition to several air handling units. The system should be completed over the coming months and fully operation in time for the opening event the Ed Sheerin concert in early March 2018. 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.
