Regional plumbing and drainage inspections
In regional NSW, inspection and enforcement are delegated to local councils and authorities. Learn more.
Who to contact
To find out who carries out the plumbing regulation functions in your area, see local plumbing regulators in NSW.
To arrange a local plumbing inspection, contact your local plumbing regulator.
When to arrange an inspection
Inspections need to be booked by a plumber or drainer usually at the following stages:
- After drainage work is completed, but before it’s backfilled or covered.
- After connecting to a Network Utility Operator’s sewer main, but before backfilling.
- After water supply work is completed, but before walls or ceilings are sheeted or covered.
- If a re-inspection is needed, or if previous work was non-compliant.
- When all plumbing and drainage works are finished prior to occupation.
Contact the relevant local plumbing regulator to confirm their inspection requirements.
Documents you'll need
Plumbers and drainers must submit the following documents at specific stages of the work.
You must submit the:
- Notice of Work to the local plumbing regulator before the work begins.
- Certificate of Compliance on completion of the final inspection to the local plumbing regulator, and provide a copy to the person for whom the work was carried out.
- Sewer Service Diagram to the local plumbing regulator, and provide a copy to the owner of the land or the owners agent.
