WaterMark Certification Scheme

WaterMark Logo

The improved Scheme was launched on 1 July 2016 and commenced progressive implementation from 1 August 2017.

The WaterMark Certification Scheme (Scheme) is a mandatory certification scheme for plumbing and drainage products to ensure they are fit for purpose and appropriately authorised for use in plumbing and drainage installations.

The ABCB manages and administers the Scheme as a national scheme. The NCC, Volume Three requires certain plumbing and drainage products to be certified (listed on the Product Database) and authorised for use in a plumbing or drainage installation. These materials and products are certified and authorised for use through The Scheme.


The Scheme originated as the National Certification Plumbing and Drainage Products Scheme in 1988 through a voluntary arrangement between Standards Australia and participating plumbing and drainage regulators in Australia. As there was no national regulator for plumbing, the National Plumbing Regulators Forum (NPRF) was formed in 2002 and it subsequently published the first version of the PCA in 2004 which referenced the Scheme. The NPRF managed the Scheme and Standards Australia were the administrators.

In February 2013 management and administration of the Scheme transferred to the ABCB. Following a review of the existing Scheme and stakeholder consultation an improved version of the Scheme was launched on 1 July 2016. The Manual for the WaterMark Certification Scheme, outlining the rules for the improved Scheme, was published in June 2017 in preparation for the progressive implementation of the improved Scheme on 1 August 2017.
