Decommissioning of OSSM systems will be required when:

  • The property is connected to reticulated sewer, or
  • An old OSSM system is replaced with a new one

In these instances, the owner is required to contact Council regarding decommissioning of the system. The owner must decommission the system in accordance with Council’s requirements to prevent any future safety, environmental or public health risks. Council can provide information on the steps that need to be followed to decommission an OSSM system.
