Plumbing and drainage

In accordance with the provisions of the Plumbing and Drainage Act 2011 and Regulation, from 1 January 2013 the NSW Office of Fair Trading is the single plumbing and drainage regulator for all on-site plumbing and drainage work in NSW.  Fair Trading has delegated certain functions under the Plumbing and Drainage Act, 2011 to Shoalhaven City Council for plumbing and drainage works within the city boundaries.

All plumbing and drainage work must comply with the Plumbing Code of Australia and Australian Standard AS/NZS 3500.  Copies of the Plumbing Code of Australia can be obtained from the Australian Building Codes Board at www.abcb.gov.au and copies of AS/NZS 3500 can be obtained from www.siaglobal.com

NOTE: Shoalhaven Libraries provide online access to the Australian Standard AS/NZS 3500.  Please note due to copyright restrictions, copies of the documents are unable to be made.

Fair Trading licenses plumbers and drainers under the Home Building Act 1989, and all plumbing and drainage work must be completed by a person holding a licence, qualified supervisor certificate or tradesperson certificate.

Plumbers and drainers working in the Shoalhaven Local Government Area continue to contact Shoalhaven City Council to book inspections, pay fees, submit documentation and for enquiries.

Documents and forms
Plumbers and drainers are required to submit the following documents at certain stages of the work:

  • Notice of Work is to be issued to Shoalhaven City Council no later than 2 business days before the work concerned is carried out.
  • Certificate of Compliance is to be issued to Shoalhaven City Council and to the person for whom the work was carried out, on completion of the final inspection.
  • Sewer Service Diagram is to be issued to Shoalhaven City Council and the owner of the land or the owner's agent at the completion of the drainage works.

What work requires a Notice of Work?
A Notice of Work is required for any plumbing installation downstream from the point of connection to a water supply and any sanitary plumbing or drainage work from the fixture to the point of connection with the local utility operator.  The Notice of Work must be completed by the licensed plumber or drainer.
