New Icon Water water supply and sewerage standards

In 2018, we are continuing the process of transitioning from our current water supply and sewerage standards to Water Services Association of Australia (WSAA) national codes.  As part of this transition, the following work is planned:


  • Our existing "WSS series" of standard drawings will be replaced by new “SD series” drawings which are predominantly based on WSAA standard drawings and well-proven Australian urban water industry standard practices. These new drawings will depict how our water supply and sewerage networks are to be designed and constructed. The first batch of these “SD series” drawings have now completed their public consultation period (3/01/18 – 01/06/18). This batch of drawings is available for download as a single PDF file (which includes an accompanying set of explanatory notes and frequently asked questions):

SD Series Drawings - Batch 1 Release


  • The existing Water Supply and Sewerage Standards (WSSS) will be replaced by WSAA codes: WSA-02 Gravity Sewerage Code of Australia, WSA-03 Water Supply Code of Australia, and WSA-04 Sewage Pumping Station Code of Australia. Supplements to WSA-02 and WSA-03 have undergone public consultation (now complete as at 01/06/18) but are still available for download via the web-links below. A supplement to WSA-04 will become available by the end of June 2018. Even though we are publishing supplements, designers and constructors will still need to be familiar with each individual code and these can be purchased directly from the WSAA website online store.

Supplement to WSA 03-2011 Water Supply Code of Australia


  • Plumbers whose scope of works is limited to the installation of water meters and consumer premises plumbing from the property connection (aka “tie”) point do not need to purchase WSAA codes or refer to the Icon Water WSA 02 and WSA 03 supplements. Instead, we have published a small specification for this purposes (which has undergone public consultation (now complete as at 01/06/18)) and this is available for download via the web-link below:

Requirements for Property Service Connections and Water Meters

  • Additional specifications and guidance material will be published on our website which will further augment our new WSAA code supplements. Such material will not necessarily go through a public consultation period in all cases. In late 2017, the new Approved Products List, Supplement to AS 1657 and Design Guidelines for Safe Access, Egress and Working at Heights all went through a lengthy period of public consultation and these documents have now been issued for mandatory use. Refer to “Specifications and Rules” below.
  • Information sessions were held in March and early April 2018 for designers, developers, consultants, constructors, plumbers, drainers and other interested parties. A PDF file containing slides from these information sessions is available for download:

  • A new specification which describes the revised “Asset Creation and Acceptance Process” and accompanying forms are now available for download and review via the web-links below. The review period will finish on 22 June 2018. Should you wish to provide feedback on these documents, please do so by emailing us at Note: The proposed "go live" date of our new standards is targeted to occur on 2 July 2018.

Asset Creation and Acceptance Process (ACAP)

ACAP: Advice on Commencement of Hydraulic Works Rev 03

ACAP: Application for Provisional Certificate of Operation Rev 05

ACAP: Design Form Pack Major Works Rev 03

ACAP: Design Form Pack Minor Works Rev 03

  • A new specification for “Survey and Tolerancing” and a revised “Drafting Standard” will be made available for review and public feedback by the end of June 2018. Icon Water is working with TCCS and the Surveyor-General’s office with the aim of harmonising construction tolerances, survey requirements and Work As Executed (WAE) drawing requirements with TCCS.
