Eyre Peninsula desalination project

We reached a project milestone this month with the arrival of a drilling rig. The rig, which is 23 metres long, will bore holes for piles, which will support the marine pipeline’s tunnel boring machine.

During September, activities at the wastewater treatment plant included:

• Backfilling of old lagoons to prepare for new marine pipe infrastructure.

• McConnell Dowell, our contractor for building marine infrastructure, taking possession of the area where the marine intake pump station will be constructed.

• Preparation of an amenities pad for new site huts, which will be established soon.

Acciona, our partner that is building the reverse-osmosis component of the desalination plant, has been busy establishing its huts on site. They are now starting preliminary civil works to prepare for the construction and installation of the site’s buildings and reverse osmosis filtration systems.

We’ll continue to share project updates as we work toward delivering first water by the end of 2026.

Construction is now in full swing, moving us closer to securing a long-term, climate-independent water supply for the Eyre Peninsula. Crews have cleared the vegetation at the desalination plant site, and an old rail embankment has been taken out, removing 800 tonnes of material. A new access road has been built, erosion controls are in place, and a truck wheel wash has been installed to keep roads clean.

At the Marine Intake Pump Station site, an amenities pad has been prepared, and decommissioning of underground services is progressing, clearing the way for the project’s new pipe infrastructure. The final design for the new access road has been approved, and construction will commence shortly.

Material continues to be transported along St Andrews Drive from DK Quarries to our Marine Intake Pump Station site. This soil is needed to backfill the former wastewater treatment plant lagoons, so we can then establish a base pad for the construction of the shaft for the marine intake and outfall.

We’ve made major strides in connecting the desalination plant to the local electricity network, with most of the cabling within Port Lincoln township complete. Next, we’re installing power poles along the stretch between Windsor Avenue and Greyhound Road, and at the Wastewater Treatment Plant site, ensuring the desalination plant has a reliable electricity supply.

Meanwhile, work along the pipeline route is progressing, with vegetation removal nearly finished. We’re enhancing local habitats with environmental offsets, which are part of our approved environmental management plan. The project team is working closely with the local council and stakeholders to sustainably manage and implement this plan.

The project continues to progress, with major contractors confirmed. ACCIONA, which led the Early Contractor Involvement phase, has been awarded the full contract to deliver the desalination plant and will manage the overall project construction. McConnell Dowell, a globally recognised leader in marine construction, is delivering the marine infrastructure components which involves tunnelling beneath the ocean floor to minimise coastal disturbance. South Australian company Leed is designing and constructing the transfer pipeline connecting the plant to the existing water network. Environmental management remains a key priority, with design and construction adjustments reducing the project’s environmental footprint.

With our project partners now confirmed and detailed designs complete, the project has reached a major milestone by entering full construction. Early site preparation, including native vegetation clearing, access road installation, and removal of the old rail embankment is complete. Civil works are underway at the Marine Intake Pump Station site, including excavation, backfilling, and construction of the pump station guide wall. Electricity cable installation by SA Power Networks in Port Lincoln is complete, and Leed continues with transfer pipeline works and vegetation clearing along the route.

Community safety remains a priority with increased truck movements expected from August. Leed is hosting a Meet the Buyer session on 31 July at the SA Water Project Delivery Office in Port Lincoln to connect with local suppliers. Water security initiatives continue across the Eyre Peninsula as our Water Security and Futures team engages with the community.

The Eyre Peninsula desalination project continues to develop across a range of key areas. Early works at the plant site continue steadily, with major construction and infrastructure installation planned soon. Site security improvements and vegetation clearing are progressing to support these activities. At the same time, SA Power Networks is installing underground electricity cables to connect the plant, with careful traffic management in place to minimize disruption. The project team is also actively engaging the community through water security initiatives, including outreach at local events and industry roundtables promoting water-saving practices. Additionally, the workforce transition program recently welcomed internationally trained engineers to learn about regional opportunities and project innovations.

Progress continues across multiple fronts of the Eyre Peninsula desalination project.

SA Power Networks has begun cable installation from the Port Lincoln substation to Billy Lights Point, including works along key streets and near the wastewater treatment plant, with traffic management and some night works planned.

On site, early works include temporary fencing, vegetation clearance, and the setup of site access and facilities to prepare for major construction. Design of the transfer pipeline to the Northside Hill storage tanks is well advanced, with geotechnical investigations completed to support the route. Community engagement remains a priority, with recent outreach at local events and ongoing efforts to promote water security and efficiency.

Works are underway to connect the Eyre Peninsula desalination facility to the local electricity network, including underground cabling and overhead powerline installation across several Port Lincoln streets.

Construction will run from May to December 2025, with some night works and traffic impacts expected. SA Power Networks is working to minimise disruptions, and affected residents will be notified directly.

Early works continue with several activities progressing as planned. Logs have been relocated for wildlife habitat at Uley South, temporary fencing is in place, and vegetation clearance is advancing, including along St Andrews Drive between the desalination plant and the wastewater treatment plant. Design for the Marine Intake Pump Station entrance is ongoing, with efforts to minimise vegetation removal. A site office and staff amenities will also be established at the wastewater treatment plant to support efficient daily operations.

Alongside early works, local schools and the broader community have been actively engaged through a range of educational and outreach activities. Nearly 140 students from two Port Lincoln schools recently participated in interactive sessions on desalination, following the Water Detectives live show as part of the Our Water, Our Future program. Meanwhile, SA Power Networks will soon begin trenching works to connect power to the plant site, with activities scheduled to run from late April/early May through July. Meanwhile, the Water Security Roadshow wrapped up in Port Lincoln, sharing updates on water restrictions, available rebates for efficient appliances, and long-term plans to secure the region's drinking water supply, while encouraging sustainable water use and ongoing community involvement.

Early works for the Eyre Peninsula desalination project are progressing, with vegetation clearance underway along St Andrews Drive and preparations for the Marine Intake Pump Station (MIPS) continuing. A site office is being set up to support ongoing activities, and Marina residents have received project updates via a letterbox drop. Locals are encouraged to sign up for notifications to stay informed about construction updates.

To support biodiversity, over 200 salvaged logs are being repurposed as wildlife habitats at Uley South. The Water Security team is engaging with communities through pop-up sessions and local events to share water-saving measures. Meanwhile, the Port Lincoln Project Information Centre has transitioned into a Project Delivery Office to assist the public. For more details, view the March 2025 project update.

Early works for the project are being completed in stages, with Stage 1 now completed and Stage 2 set to begin in late February or March 2025.

Stage 1 included the removal of waste (303 vehicle tyres and 13 tonnes of general waste), environmental testing and clearing vegetation for site security.

Stage 2 will involve further vegetation clearing, relocation of logs for wildlife habitat, and construction of a new access road to the wastewater treatment plant site. A site office will also be established. Some traffic management will be needed on St Andrews Drive which may result in some minor delays for those travelling to the Billy Lights Point Boat ramp.

What’s next

Construction of the desalination plant and Marine Intake Pump Station (MIPS) is expected to begin in late March, while the transfer pipeline construction is not expected to start before mid-2025.

For more details, view the February 2025 project update.

With development approval granted, we are ready to proceed with some initial works, which are expected to begin before Christmas.
