Vacuum Drainage

Vacuum Drainage Systems

Avac offer a range of vacuum drainage solutions for new constructions and renovation projects.


What is a Vacuum Drainage System?

Vacuum drainage systems use the combined energies of vacuum pressure and gravity for the collection, conveyance and disposal of waste through a piping network that can be routed above ground. Vacuum drainage systems consist of three main components: a vacuum generating station (Vac Centre), a conveyance system and individual collection points.


When to Choose a Vacuum Drainage System?

Conventional drainage systems impose significant design constraints for all new and existing constructions. The requirement for fall in the piping means that conventional systems are typically located either subterranean or in the slab and are subsequently "set in concrete". Changing the location of the piping or adding fixtures is extremely costly and difficult to achieve. In contrast, Vacuum drainage systems are extremely versatile, they can be routed to run uphill, around site constraints and fixtures can be easily moved, added or removed at any time with minimal cost and disruption.

 

Products

Avac has played an integral part in the development of Vacuum Sewage Systems in Australia, particularly Queensland's penal system. Click the image on the left to learn about the features and benefits of an Avac Sewage System, or explore our technical information or recent projects through the links below.

 
Vacuum drainage systems work in concert with the new "open" architectural store environment, where electrical and refrigeration services are brought to display cases from overhead. Drainage can now follow these services, allowing flexibility in store layout.

A vacuum system can be used to remove small amounts of grey water from fixtures such as basins, or large amounts for example from a stadium washdown or storm water. To learn further about the features and benefits of using a vacuum system to remove grey water click the image on the left, or take a look at how vacuum was used in the MCG!

 

Avac vacuum toilets remove waste by utilising vacuum pressure maintained in the vacuum piping network. Avac has installed over 3000 fixtures through out Australian correctional centres alone. Click the link on the left to understand the features and how they might benefit your installation.
