Install or Alter a Septic Tank System
Decommission a System
If your septic system is no longer needed (e.g. you have connected to sewer or installed a new wastewater system) then the system must be made safe.
To decommission a system you will need to engage a licensed plumber to complete the works.
The plumber will:
- Have a pump out agent pump out the tank, rinse it with water and pump out the rinse water
- Break the tank bottom, collapse the walls and top to below ground level
- Use clean fill to bring area back to level with surround areas
- Complete the Decommissioning a Septic System Form and return to Council. We recommend that you keep a copy of the completed form
