From the 1st January 2013, NSW Fair Trading has become the single regulator for plumbing and drainage inspections for the state of NSW. In areas outside of Newcastle, Sydney and Wollongong, NSW Fair Trading delegates its powers, functions and responsibilities to regional authorities such as local councils. Gundagai Shire remains the plumbing and drainage regulator for works in residential and commercial context.
With the introduction of the new Plumbing Code of Australia since 1 July 2012, and several key reforms coming on board since October 2012, changes have been made to achieve compliance with the Deemed To Satisfy provisions of the new Code. The NSW Code of Practice for Plumbing and Drainage is no longer in use. The new Code with the Building Code of Australia form the suite of industry requirements known as National Construction Code updated on an annual basis.
The new Plumbing and Drainage Act 2011 plus its Regulation 2012 set out the legislative requirements for conduct of plumbing / drainage works in NSW.
Plumbers are advised that plumbing and drainage works carried out in the shire must be inspected by Council's inspector, and a Notice of Work is to be lodged 48 hours prior to commencement of work. Certain materials used for plumbing and drainage installations must comply with the Australian Standard 3500, Plumbing Code of Australia and WATERMARK © certification. Further details on WATERMARK © can be found on

Plumbers are required to lodge a Certificate of Compliance with Council in relation to all completed internal and external works. Copies are provided free of cost. A sewer sanitary diagram is required to enable the issuance of an Occupation Certificate.
