Plumbing and drainage inspection process
1. Lodging a Notice of Work
A Notice of Work (NoW) is a form that specifies the plumbing and drainage work to be carried out.
By law, plumbers and drainers must submit a Notice of Work before starting work, except in some circumstances, for instance, the legislation exempts emergency work and minor works if the location of fixtures does not change.
You can lodge the Notice of Works with Council online, in person or by post. When a Notice of Works is submitted, Council generates a plumbing and drainage application, allocating a plumbing and drainage reference number. You will need to use that number in further interaction with Council.
2. Paying inspection fees
You will need to pay for an plumbing and drainage inspection fee when you lodge an application.
There are two types of fees:
- New works (up to four inspections).
- Refit or alter (up to two inspections).
We may charge for required additional inspections.
3. Booking inspections
You need to submit a Notice of Work (Plumbing and Drainage application) and pay inspection fees before booking an inspection, which you can do online or by calling 02 4921 0333.
Inspections are required when:
- internal and external plumbing, prior to covering and backfilling, where non-reticulated tank water is used as the water supply
- internal and external plumbing and drainage, prior to placement of slab and backfilling, where no sewer is available, and an on-site sewerage management system is proposed.
Inspections are generally required when:
- drainage work is completed and prior to backfilling or covering the installation
- a connection to a sewerage system is completed or prior backfilling
- there is a need for re-inspection or for an inspection of non-compliant work.
In certain circumstances, an inspection may be carried out at any time during the installation process, for instance, when the sanitary plumbing is finished and before the premises are occupied.
Inspections are available between 7am and 3pm on weekdays.
For more information, contact Council on 02 4921 0333.
