Septic Tank Decommissioning

Septic tank decommissioning is a crucial process when a property is connected to the municipal sewer system or when changes to property use or ownership occur. SAGGERS Wastewater & Civil Solutions provides professional septic tank decommissioning services in Perth and across Western Australia, ensuring systems are safely removed or permanently deactivated in compliance with local regulations.

Understanding Septic Tank Decommissioning

Decommissioning a septic tank involves permanently removing or safely disabling a septic system once it is no longer in use, most commonly after a property connects to the municipal sewer system. Proper decommissioning prevents risks such as tank collapse, soil contamination and safety hazards, while ensuring compliance with health and environmental regulations.

When is Decommissioning Necessary?

Septic tank decommissioning is legally required in several situations to ensure public safety, environmental protection and regulatory compliance.

Connection to Sewer
When sewer connection becomes available, properties must connect to it within five years, or within one year if the property is sold. Decommissioning of the existing septic system should occur soon after the sewer connection to prevent any future risks.
Property Sale
New owners are required to decommission the septic tank within 60 days of taking ownership. This requirement is often managed during the property settlement process.
Construction and Property Use Change
If construction work occurs within 1.2 meters of a septic tank or directly above it, or if the property’s use is changed (e.g., converting a residence into a business), the septic system must be decommissioned within 60 days to avoid complications.

The Decommissioning Process

Our decommissioning process is thorough and adheres strictly to legal and safety standards:

Emptying the System
A licensed liquid waste contractor will pump out all septic tanks, leach drains, and soakwells to ensure they are completely emptied.
Removal or Filling
Depending on the site conditions and future use of the area, the emptied septic components may be physically removed. If removal is not feasible, the bottoms and lids of the tanks are broken up, and the cavities are filled with clean fill, such as yellow sand, to ensure stability and safety.
Compaction
After filling, the material is compacted thoroughly to prevent any future subsidence that might lead to safety hazards.
Compliance & Site Sign-Off
Where required, we assist with documentation and site readiness to support local council or regulatory compliance following decommissioning.
