Mobile home and portable toilet cartridge dump facility

Mobile home and portable toilet waste includes waste from mobile homes and portable cartridge type toilets for caravans.

Mobile and portable toilet cartridge waste has an organic content many times that of normal domestic wastewater, and may contain various treatment chemicals. It's a waste which, in commercial quantities, must be controlled through our trade waste permitting system.


  • All portable toilet waste that is to be discharged to the wastewater system must be disposed of at designated mobile home and portable toilet cartridge dump facilities which could be located at caravan parks, roadside stops, showgrounds and other locations.
  • An application to discharge trade waste must be submitted for assessment prior to the installation of any proposed discharge point.

  • All designated discharge points must have a permit held by the party that owns, operates and provides the facility. In the case of caravan parks that may have several dump points, each one is designated separately on a single permit. 
  • Mobile home and portable toilet cartridge dump facilities are to be constructed with a bounded area to prevent any spillage to the environment. The minimum outlet is to 150mm (LIT) connected to 100mm gully.
