Our Pipeline Delivery Program [PMP] consists of numerous sites across South Australia and involves the replacement of infrastructure approaching end-of-life, augmentation works in rural areas to deliver greater volumes of water with increased reliability and upgrades to existing infrastructure such as valve replacements.

The projects are all varied in scope and complexity, with sections of large-diameter trunk mains running through public land and within easements on private property, across farming land and within challenging terrain.

  • BEETALOO TRUNK MAIN REPLACEMENT

The Beetaloo Trunk Main plays a vital role in the region’s water network, transferring water from the Morgan–Whyalla Pipeline at Crystal Brook through to the Bundaleer Trunk Main near Mundoora. Originally constructed in the 1930s, the pipeline has supported water supply across the Upper Yorke Peninsula for decades.

This project will deliver the replacement of 6.8 kilometres of large diameter pipeline, alongside the decommissioning of redundant pipelines and associated assets. Works will be completed across three sections spanning 15km. Much of the work will take place within easements on privately owned farming land.

Key construction activities will include open trench excavation, installation of new pipeline, nine creek crossings and removal and capping of existing pipework at tie-in points.

The image below shows the pipeline alignment, with the green sections indicating completed sections, and the red being those currently underway. Once complete in late 2026, the project will bolster water security to the region and ensure the ongoing performance of this essential supply network for years to come.

  • FREELING GROWTH

This project is being delivered to increase the capability of the Barossa network through the duplication of sections of the network in parallel to existing infrastructure, as well as doubling the diameter of the water main in sections. This will benefit our customers and promote development opportunities in the Greenock area and beyond by increasing supply volumes and service reliability throughout the year.

In 2026, this multi-staged project will see over 1,400m of 200mm diameter water main laid alongside the existing 150mm main shown below in green:

Additionally, we will be upgrading over 1,800m meters of 150mm diameter water main to 300mm as shown below in green:

Project completion is on track for the end of winter 2026 whereupon the network will have capacity to supply over 1,700 new allotments in the Barossa region with clean, reliable and safe drinking water. This exciting project is aligned with SA Water's commitment to playing a key role in delivering the infrastructure expansion required to promote South Australia's housing development opportunities, which will bring economic growth to the region.

  • PORT PIRIE SOUTH TRUNK MAIN

Built in 1961 and running the length of Magor Road in Port Pirie South, this 600mm diameter trunk water main has played a critical part in supplying water to roughly 2,800 properties in Port Pirie South, Risdon Park and Risdon Park South. We are investing in the upgrade and duplication of a section of the trunk main in Magor Road that is approximately 1,700m long.

To counter historical issues the main has faced due to age and capacity, construction on the Port Pirie South upgrade will begin in mid-2026. These works will improve network reliability, lessen the likelihood of unplanned service outages and accommodate the growth seen in Port Pirie South in the past decade while meeting the needs of the continued expansion of the town's population.

The section highlighted below shows the extent of the works on green:

  • TORRENS ROAD LINK MAIN

Completed in early May of 2026, the Torrens Road Main Link Project saw the installation of a new valve in a below ground chamber in Alberton at the intersection of 2 trunk water mains. The installation of this valve on a 600mm diameter main, which runs into another large volume main, will allow for scheduled maintenance to be carried out independently on both the sections of the network by isolating via the new valve. by doing this we will be able to reduce customer impacts that would otherwise be much more far-reaching.

  • STIRLING TRUNK MAIN REPLACEMENT

With a planned construction commencement date of late 2026, this project will replace a section of in-parallel water main located in the Stirling area. This trunk main plays a much-needed role in providing drinking water to thousands of customers in the Adelaide Hills, as well as providing a crucial resource in the firefighting capabilities of the CFS. Fed from the Happy Valley Reservoir, this section of main forms part of a complex network of pipes, storage tanks and pumping stations that keep the community in drinking water and promotes agricultural and community development.

More projects will be added to this page as they approach implementation, so if you would like to remain up to date, just nominate to follow the project using the widget options above.
