If your property is not connected to public sewerage infrastructure, you will need an on-site sewerage facility (OSF). This facility stores, treats and disposes of your domestic sewerage on your property. An OSF consists of two components; the treatment plant and the land application area. For a more comprehensive guide refer to council's what is an OSF fact sheet.
All OSF's need a plumbing permit (approval) from council before installation. You need to apply for a permit if you are installing a new OSF or altering an existing system.
To apply for a permit, use form 1 permit work application for plumbing, drainage and on site sewerage work.
Once approved, you will receive a copy of the permit and approved plan. Then a licensed drainage contractor can install the facility. It is the responsibility of the contractor to:
- install the facility correctly
- ensure completion of inspections and certifications
- provide a final inspection certificate to the owner.
