Hunter Water's standard drawings depict our default construction practice requirements for our water and sewer systems.
In some cases, particular projects may dictate that these default requirements be modified by project designers.
These standard drawings were developed by us, are to be used for construction of water and/or sewerage works that are to become the property of Hunter Water.
It is intended that the works be designed in accordance with our design manuals and that these standard drawings be used in conjunction with the standard technical specifications, other standard drawings and requirements prepared specifically for each particular project.
Gravity Sewer DN150- DN750 and Watermains DN100-DN750 standard drawings have been superseded by design drawings included in WSA02 Sewerage Code of Australia Hunter Water Edition and WSA03 Water Supply Code of Australia Hunter Water Edition.
