Septic Tanks
Septic Tanks
The Environmental Protection Act 1970 requires that all systems for the treatment and disposal of waste water up to 5,000 litres per day must be approved by local government prior to installation and/or alteration.

When building a house or extending to add more bedrooms you will need to apply for a permit to install or alter a septic tank system.

Permits are valid for two years and construction of the system must be installed as outlined in the permit to install.

A 'Permit to Use' will be issued once the system is installed, all necessary inspections completed and the plumber's compliance certificate submitted.

Once you have completed a septic tank application form and please send your form with the following documents:

  • The fee for either installation or alteration
  • A plan of the location of the site
  • A site plan of the prosed installation
  • A copy of the land capability assessment report
  • A copy of certificate of conformity (only required for aerated wastewater system)

  • Alter a septic tank system application: $294.50
  • Renew permit to install: $235.00
  • Search for septic tank plans: $24.00

You can get more information and advice by contacting council.

The system you install must be approved by the Environment Protection Authority (EPA). Visit the EPA website for more information.
