Avac Australia’s vacuum drainage technology provides Airport facilities managers and project leaders with the ability to refurbish without excessive trenching while ensuring minimal interruption to flight schedules and traveller movements. We provide workable solutions where post-tensioned slabs or weight-rated concrete slabs pose significant structural or cost inhibitive challenges for conventional gravity designs.
Our faster construction turnaround allows for a quicker ROI as retail outlets are able to start operating sooner while providing a more pleasant travel experience for passengers and shoppers.
Any airport terminal redevelopment construction schedule needs to accommodate regular flight schedules with minimal dust, noise and interruption. Avac’s solutions allow for faster hand-overs with little to no slab penetrations or trenching.
Our ability to re-route piping and move multiple waste streams [e.g. greywater, sewerage and trade waste] provides airport facilities managers with greater options to offer potential tenants. For example, a bookstore can now install a coffee bar or alternatively, a burger chain could move into a space vacated by a dress shop.
Avac’s Vacuum sewerage piping network can be fitted above ground which provides a far greater level of protection against potential leaks and subsequent damage to critical equipment such as baggage conveyor systems, CT X-ray machines and pre-existing services.
If a pipe is damaged and a leak occurs, it is much easier to locate and repair the leak in a vacuum system, than in a traditional gravity system. Importantly, as the system is under negative pressure, wastewater cannot leak out of the piping network meaning contamination is always contained.
Avac vacuum toilets are some of Australia’s most efficient and use from as little as 0.7 litres of water per flush, providing a significant reduction in annual water and sewage costs when compared to conventional toilets. This can be as much as 3.2 litres per flush multiplied by the number of patrons who travel through the airport annually, i.e. more than half of all toilet flushing water will be saved. This translates to further savings via the down-sizing of wastewater treatment plant.
Our systems allow extremely fast evacuation of waste and immediate recovery of the fixture during peak periods. Conventional systems struggle to cope with high loads of flushing and slow recovery of the fixture [e.g. cistern refills] and often become blocked.
