We work to the following standards:

  • BS EN 12109-1999 Vacuum drainage systems inside buildings

As part of our ongoing effort to bring environmentally sustainable and economically efficient vacuum waste management solutions to the Australian market, we have actively participated over the past 5 years within the Plumbing Products Industry Group and its Vacuum Drainage System Special Interest Group. This industry group, of which H.I. Fraser is an active participant, is currently developing the Australian Standard for vacuum drainage systems within buildings for the benefit of the Australian Community.
