Water & Sewer Design Manuals

This page contains links to Hunter Water’s design manuals for our water and wastewater networks. When designing assets it is the designer's responsibility to collaborate with Hunter Water and ensure that requirements of adopted design standards are suitable for each particular application.

Previously all Hunter Water network assets were designed in accordance with the Hunter Water produced document called the “Water and Sewer Design Manual”.  Hunter Water is progressively replacing sections of our internal guideline with bespoke Hunter Water Editions of the Water Services Associated of Australia (WSAA) design guidelines.

To date, Hunter Water has adopted WSA 02 “Gravity Sewerage Code of Australia” and WSA 03 “Water Supply Code of Australia”. These integrated editions of the design codes replaced Sections 1, 2 and 3 of the Hunter Water Design Manual. Other WSAA design codes are being reviewed for future adoption. 


Adopted WSAA Design Manuals

Hunter Water currently adopts Hunter Water Editions of the following two WSAA standards:

  • WSA 02 - Gravity Sewerage Code of Australia - Hunter Water Edition - Version 2.1
  • WSA 03 - Water Supply Code of Australia - Hunter Water Edition - Version 2.1

These standards are available through WSAA from their online shop. Further information on Hunter Water’s adoption of WSA 02 and WSA 03 can be found on our WSAA Codes Publication page.

Guidelines on Asset Operation and Maintenance Costs

As of October 2019 Hunter Water has repealed its outdated "Operating and Maintenance Cost Estimation Guideline" previously available from this webpage.  This document provided general advice on O&M costs associated with various water and sewer assets and also documented assumptions on projected electricity rates charged by Hunter Water.  It was primarily used to compare the cost impact of different servicing options.  A replacement document is currently in development.  Please email our team if you require any specific advice in the meantime.
