The SEQ Code has been developed collaboratively by the five SEQ water service providers.  It complies with with Chapter 4A of the South East Queensland Water (Distribution and Retail Restructuring) Act 2009.  More information on how the SEQ Code was developed can be found on the Consultation page.

The core of the SEQ Water Supply and Sewerage Design and Construction Code is the five National Codes developed by WSAA:

  • WSA 02-2002 Sewerage Code of Australia, Version 2.3
  • WSA 03-2011 Water Supply Code of Australia, Version 3.1
  • WSA 04-2005 Sewage Pumping Station Code of Australia, Version 2.1
  • WSA 06-2008 Vacuum Sewerage Code of Australia, Version 1.2
  • WSA 07-2007 Pressure Sewerage Code of Australia, Version 1.1

The National Codes have been widely adopted by WSAA members and associates for the urban water industry.  Each water service provider is required to close out options within each National Code to accommodate their needs and preferences as well as local construction practices and products. 

The National Codes are supported by the activities of other WSAA committees and networks that focus on broader issues such as sustainability, environmental management, asset management, water quality, quality assurance, water reuse and conservation, pressure and leakage management, OH&S, critical infrastructure protection, strategic products and construction materials

The National Codes are copyright protected by WSAA.  They may be purchased from the WSAA Code Shop.

It is the intention of the SEQ water service providers to work with WSAA to release fully integrated versions of the National Codes.  However, this will not occur until there has been sufficient time to identify errors and inconsistencies in the SEQ Code.  In the meantime, SEQ Amendments to the five National Codes can be downloaded from the Standards page.  Other water service providers from around Australia have collaborated with WSAA to release their own versions of the National Codes.

Other key documents that form part of the SEQ Code include:

These documents can be downloaded from the Standards and Products pages.

The five SEQ water service providers recognise that the SEQ Code will need regular review and revision.  Standards should not be so immovable that innovation and new fit-for-purpose products are excluded.  Details of how individuals and organisations can suggest improvements to the SEQ Code are provided on the Consultation page.
