Avac’s vacuum plumbing systems can be of tremendous benefit in the renovation of historical buildings in which both mechanical design and preservation of the existing structure must be taken into consideration.


Design Flexibilty

As Avac’s vacuum drainage designs enable the waste pipework to step up, it can be easily routed around fire and electrical services whilst avoiding damaging heritage protected features of the building.


Stay within the Tenancy

Construction and refurbishment remain within the tenancy which eliminates the reliance on penetrating the slab or floor.  This means Heritage redevelopment projects which may previously have been considered as untenable can become viable.

Saves Water and $$

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.

Calculating the savings compared to conventional toilets is as much as 3.2 litres per flush multiplied by the number of people who use the building 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.

Improved Construction Schedules

Because trenching is eliminated, store remodel activities are less expensive, safer, more sanitary, and take less time which minimises customer attrition rates.
