Water & Sewer Design Manuals

Our Network Design Standards define parameters and practices to be adopted when designing particular components of Hunter Water's water supply systems and gravity sewerage. When designing assets it is the designer's responsibility to ensure that requirements included in the design standards are suitable for each particular application.

In July 2017 Hunter Water released Version 2.0 of the Hunter Water editions of the Water Services Association of Australia (WSAA) WSA 02 Gravity Sewerage Code of Australia and the 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.

Current Hunter Water Design Standards

WSA02 and WSA03 are available from WSAA. View our WSAA Codes Publication page.

The Guideline - Water and Sewer Cost Estimating contains assumptions regarding electricity prices, infrastructure operational and maintenance costs and greenhouse gas abatement rates that should be used when conducting a business case or Net Present Value (NPV) analysis for projects.
