Inspections

Onsite sewage management facilities are assessed as either:

  • high risk or
  • low risk.

Facilities are assessed based on their proximity to waterways, soil types and flood risk.

They are inspected to ensure they are operating effectively and not affecting human health or the environment.

Our Environmental Health Officers inspect:

  • high risk facilities annually
  • low risk facilities every four years.

A Certificate of Audit and and Approval to Operate (for 1 or 4 years) is issued if your facility is compliant.

If your facility is not compliant our Environmental Health Officer will discuss how to fix the problem.
