Tarro to Shortland Trunk Main
Installation of a underground pipeline.
Built on the success of the Ash Island Trunkmain project, Diona secured a further contract to replace an existing pipeline from Tarro to Shortland. This project is located primarily within the Hexham Swamp and Nature Reserve.
The original pipeline is operated by Hunter Water, delivering water from Dungog Treatment Plant to the Maitland and Cessnock systems, as well as forming a crucial link between the Newcastle and Maitland systems. It was Diona’s responsibility to design and construct the new 7.4 kilometre pipeline and remove 8.1 kilometres of the original pipeline.
