Exploring a new secure and sustainable water supply for the future.

What's being decided/considered?

Northern Water is investigating the option of a seawater desalination plant in the Spencer Gulf at Cape Hardy. The desalination plant would be connected to the Upper Spencer Gulf and northern South Australia via approximately 600km of pipeline.

Aimed at addressing the limited sustainable water supplies in the Far North and Upper Spencer Gulf Regions of South Australia, and encouraging growth of the industries crucial to achieving net-zero goals, including the emerging clean energy and hydrogen industries, Northern Water would provide a climate-independent water source.

The map below illustrates the proposed project pipeline.

During 2024 - 2025 we will undertake a range of project planning, design and assessment activities to understand potential project opportunities, benefits, impacts and costs.

Activities will include:

  • Formal tender process and development of agreed contract terms with a preferred contractor to design, build, operate and maintain the plant and pipeline
  • More detailed evaluation of the overall environmental, social and economic impact of the project
  • Progression of Cultural Heritage Survey and Native Title negotiations
  • Land access negotiations for the plant and pipeline
  • Ongoing engagement with stakeholders and the community to ensure risks and opportunities are properly understood and addressed
  • Other activities required to provide Government with clear understanding of the risks and opportunities associated with the project.

The project team is seeking feedback from the community, stakeholders, landowners, and traditional owners to inform the assessment process and assist in making a final decision on the project.

Your feedback will help identify management measures to reduce risk and enhance local community benefits.

Background

An extensive site selection process commenced in 2022, which included input from key stakeholders, technical investigations, and a formal multi-criteria-assessment (MCA) process.

Three sites were initially short listed (at Crag Point, Port Lowly and at Mullaquana Station), with Mullaquana Station best performing in the initial MCA scoring process. In mid-2023 a fourth site at Cape Hardy was added to the short list following additional industry interest that would reduced the financial impacts of constructing the plant so far south in the Spencer Gulf making it a potentially feasible option.

Early engagement with key stakeholders was favourable towards Cape Hardy as a potential site for the desalination plant and a supplementary MCA process was undertaken for the Cape Hardy site in mid-2023. This identified Cape Hardy as the best performing site across the four options considered.

We consulted with the local community and stakeholders regarding the outcomes of the MCA and most people indicated their support of Cape Hardy as the better site to focus on for further study.

We presented the MCA result and the stakeholders and community feedback to the South Australian Government to help inform the selection of a preferred study site for further investigations.

  • Onshore and offshore Geotechnical begins at Cape Hardy

    If you’re in the area over the coming months, you might notice activity around Cape Hardy. It’s likely you’re seeing our Northern Water team conducting geotechnical investigations both on and offshore.

    The upcoming geotechnical investigations will comprise borehole drilling and reach target depths of between 70 and 75 metres onshore and between 35 and 60 metres offshore. This will assess this site’s subsurface soil and rock profiles to inform the project’s design and sequencing.

    In addition, shallow seafloor sediments will be investigated using vibracoring techniques (sampling techniques with minimal disturbance to the surrounding seafloor) along the proposed outfall and intake tunnel alignments.

    Samples collected during the investigation will be tested to determine physical soil and rock properties. This testing will help inform the most appropriate alignments for the intake and outfall tunnels and associated infrastructure for the proposed desalination plant.

    Once complete, and when the project has finished with the samples, we’ll give them to South Australia’s Drill Core Reference Library where they’ll become part of its world-renowned collection. These valuable samples will be available to explorers, engineers, geologists, and anyone else interested in South Australia’s rock formations as part of one of the world’s most extensive collections of drill cores.

    We’re fully aware there may be areas of cultural significance in the area, so we’ve sought advice from Traditional Owners and land holders to ensure any planned disturbance during our investigations avoid highly sensitive areas and are managed sympathetically to the surroundings.

    Snapper and King George Whiting findings are in!

    A study commissioned by Northern Water to investigate the potential impact of the project on Snapper and King George Whiting life cycles is now complete.

    A report detailing the results of the study was presented last week and concluded that there is a low to very low likelihood of impact to either species from the planned desalination plant at Cape Hardy.

    This is good news for the fish and good news for Northern Water.

    The study investigated the life cycles of Snapper and King George Whiting from spawning to egg and larval dispersal, recruitment areas, and adult movement and habitats concluding the overall risk should be considered as low.

    Experienced marine scientist, Dr Troy Roger, under the direction of Dr Mike Steer, Research Director, SARDI Aquatic and Livestock Sciences carried out this research and analysis before presenting the report to Northern Water.

    The report summary is available here

    The Commonwealth Government has announced funding contribution of $65 million towards the planning and assessment phase of the Northern Water project. This will support activities such as the environmental impact investigations, continued engagement with landholders and traditional owners, design and commercial negotiations to ensure the best outcome. These activities will ultimately inform the project Final Investment Decision expected in mid-2026.

    Funding was provided under the Commonwealth’s Future Made in Australia policy, focusing on water to unlock the potential of our Eyre Peninsula, Upper Spencer Gulf and Far North resources and build a net-zero carbon emissions South Australia.

    Geotech

    Geotechnical investigations (Geotech) have started. Geotech helps us understand the ground conditions to inform the project design. You might see our geo-technicians out in the field completing this important work.

    Most of these works will be conducted within the project corridor or in road reserves, so road users are unlikely to be impacted by these works.

    Geotech investigations are expected to continue up to the end of 2024.


    Cadastral survey

    Our surveying contractor will be on site from late May 2024 undertaking ground truthing of property boundary data (cadastral survey) at various locations along the project area.

    Most works are carried out in road reserves, meaning there will likely be no impact on traffic.

    Surveyors collect information on-site using electronic equipment. As the survey is to confirm property boundaries, the reference markers you may see on the ground do not necessarily correspond to areas impacted by the project’s final design.
