Septic Systems
Properties not connected to the sewage system require a septic system to remove, contain and/or treat waste.
New or Alterations to Septic System
Septic systems need to be designed to treat and retain all waste water on site. Applications and approval are required for:
| New Septic System |
Installation of a new septic system |
| Major Alteration to a Septic System |
Alteration to septic system and effluent dispersal system. Includes replacement or relocation of septic tank, treatment plant, sand filter, effluent dispersal system or any component of the septic tank system. |
| Minor Alteration to a Septic System |
Alterations to internal plumbing and/or inlet to the septic tank system. Installation, replacement or relocation of the internal plumbing, fixtures, fittings, appliances. |
Septic Application Process
Applications are a 3 part process:
- Lodgement
- Approval to Install or Alter
- Approval to Use
Assessment of application and inspections are included in application fee. Provided all required information has been supplied and there are no issues with the application, approval to install or alter is approximately 10 working days and the permit issued expires after 2 years from date of approval.
Note: New owners need to re-apply if septic system installation not completed at time of purchase.
Extra Time
If requiring more time to complete septic works, you can apply for an extension of time by completing the Septic Services Request Form. Fees apply. If approved, you will be issued a permit with your new completion date.
Changes to System and/or Plans
If you need to make changes to your application, you need to apply for Public Health assessment and approval of those changes. Fees may apply.
- Minor changes such as change of plumber or minor adjustments - request in writing with new plan(s) if required.
- Major changes such as change of system type, irrigation, location - new Septic System Application Form is required with amended plans (include your septic permit number).
Approval to Use
Contact Public Health to book the final inspection and approval (at least 48hrs notice required) at completion or prior to covering the system to obtain Approval to Use permit. Note: If applicable a Certificate of Occupancy Permit for the building will not be issued until a septic permit is approved.
| Please note: To comply with standards AS/NZS 1547:2012 updated February 2013, the Indicative Permeability Testing using Ksat is the new soil test required for all Septic System applications effective immediately. |
