If you do not live in an area with reticulated sewerage and you are building a house or extending an existing home to add more bedrooms, you need to apply for a permit to install or alter an OWMS.  

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 and all necessary inspections have been completed.

When you have completed a septic tank application form send your form with the following documents:

• Site plan for either installation or alteration
• Plan of the location of the site
• Site plan of the proposed installation
• Copy of the land capability assessment report (see list below)
• Copy of certificate of conformity (only required for aerated wastewater system)
• A full copy of current title for the property

An officer will contact the customer to take payment.
