Your responsibilities

If you live in a un-sewered area, you must have an EPA approved wastewater treatment system which is capable of treating the wastes produced from your house within the boundary of your premise.

How you treat the wastewater will depend on your site conditions and personal choice.

Onsite wastewater is divided into five categories:

 Sewage

 All wastewater.

 Greywater

 Water from the shower, bath, basins, washing machine, laundry trough and kitchen (also referred to as sullage).

 Blackwater

 Toilet waste.

 Yellowwater

 Urine with or without water.

 Brownwater

 Sewage without urine.


Land capability assessments

To understand your site conditions, a land capability assessment (LCA) must be conducted by a suitably qualified and experienced LCA provider.

It is very important that an LCA be carried out early in the planning phase of the development of a new house as it may have significant design implications to the site.

Planning approval is dependent on a permit to install a wastewater treatment system onsite, therefore delays can occur if an application has not been lodged.

LCA providers can be found through Yellow Pages or through an internet search.

More information on these can also be found in the EPA's LCA web publication.

Exemptions for LCA

A LCA is not required if:

  • An aerated wastewater treatment system (AWTS) is installed and 400 m2 of land application area is provided (cultivated and mulched beds); or
  • Where alterations to the house occur that do not impact the load on the current system.

PLEASE NOTE: The exemptions listed above are a general rule. The environmental health officer will determine if an LCA is not required.

Maintenance requirements

These requirements are your responsibility and are dependent on the system you have chosen to install.

Systems will be inspected at three yearly or quarterly intervals by our contracted inspection service.
