Beaudesert Water Supply Upgrade


We're connecting Beaudesert to the SEQ Water Grid and building a new water treatment plant to supply the growing Scenic Rim and South Logan regions.

We also considered additional upgrades to the Beaudesert Water Treatment Plant to produce more water. This would only allow us to meet peak demand up until around 2030, when we would no longer be able to draw enough water from the Logan River to supply Beaudesert.

The Beaudesert Water Supply Upgrade will provide a long-term water supply solution for the Scenic Rim, supporting continued population and economic growth.

On this page you can find out more about the three stages of the upgrade, provide your feedback or ask us questions.

  • Water for a growing region

    The Beaudesert Water Treatment Plant was built to serve a country town at the center of a farming and grazing community. Since then, the population of Beaudesert has grown and the town has transformed into a significant regional hub.

    As the population and economy grows, the demand for services like water grows with it. Without upgrades to the Beaudesert water supply, we will no longer be able to meet peak demand for water by 2021.

    The $135 million Beaudesert Water Supply Upgrade includes three stages:

    The $135 million Beaudesert Water Supply Upgrade includes three stages:

    1. An immediate upgrade to the Beaudesert Water Treatment Plant, including 5.1 million litres of additional water storage.

    2. The South West Pipeline, a 27 km bulk water pipeline connecting Beaudesert to the SEQ Water Grid.

    3. The new 30 million litre per day Wyaralong Water Treatment Plant adjacent to the Cedar Grove Weir.

    Long term water supply reliability in the Scenic Rim will support the continued growth of the region. Find out more about how Seqwater is planning for Our Water Future here.

  • Beaudesert Storage Upgrade

    Stage 1 beaudesert storage upgrade

    The first stage of works will immediately improve the reliability of water supply in Beaudesert by increasing the storage space for treated water, which can be drawn down upon during high demand periods.

    This upgrade to storage at the Beaudesert Water Treatment Plant addresses the immediate water supply needs of the Beaudesert area. Stored water can be used to supplement supply to Beaudesert during maintenance works, peak demand and other network shortages, improving the reliability of water supply for the Scenic Rim region. In the longer term, the new storage reservoirs will be connected to the new water treatment plant...

    Treatment process upgrades
    Works are already underway at the Beaudesert Water Treatment Plant to upgrade its treatment processes and improve reliability.

    Heavy rainfall and flood events cause agricultural pollutants and other run off to enter the Logan River, resulting in the Beaudesert Water Treatment Plant sometimes shutting down as it cannot effectively treat the river water.

    Immediate works are being undertaken to boost the resilience of the Beaudesert Water Treatment Plant to poor water quality. We are installing additional filters and treatment processes at the plant to allow it to treat river water after heavy rainfall events.

  • South West Pipeline

    Connecting Beaudesert to the SEQ Water Grid will ensure a reliable long term water supply for the Scenic Rim by making it easier to move water into the region when needed.

    The South West Pipeline will be the biggest addition to the SEQ Water Grid since completion of the Northern Pipeline Interconnector in 2012. A 24km bulk water pipeline will connect the Beaudesert Water Treatment Plant storage reservoirs to the new Wyaralong Water Treatment Plant. An additional 3km bulk water pipeline will connect the Wyaralong Water Treatment Plant to the Flagstone development area and the SEQ Water Grid pipeline network.

    Planning for the South West Pipeline is currently underway. Pending completion of the design and project approvals, we expect to start construction in 2021. We will also build a new pump station and storage reservoir at the site of the new Wyaralong Water Treatment Plant at the same time as the pipeline. The pumps will help move treated drinking water between Beaudesert and the SEQ Water Grid.

  • Wyaralong Water Treatment Plant

    Wyaralong dam   spilling 1

    The new Wyaralong Water Treatment Plant will be built adjacent to the Cedar Grove Weir, with water supplied from Wyaralong Dam.

    The new water treatment plant will be capable of producing up to 30 million litres of drinking water per day, compared to the existing Beaudesert Water Treatment Plant which produces up to 4 million litres per day. Water will be released from Wyaralong Dam to flow down Teviot Brook and the Logan River to the Cedar Grove Weir. This is similar to the way Wivenhoe Dam releases water into the Brisbane River to be treated at the Mt Crosby...

    You can learn more about how Seqwater’s dams and water treatment plants work at http://www.seqwater.com.au/education/virtual-tour.

    The Wyaralong Water Treatment Plant is still in the early stages of planning. It is being designed specifically to treat water from Wyaralong Dam and the Logan River, including any water quality impacts from recreational activity. It will incorporate cutting edge technology in water treatment processes and sustainable design. The plant will supply Beaudesert and the growing communities of southern Logan, including Flagstone and Yarrabilba.

    We expect to complete construction between 2022 and 2025, dependent on demand..

  • The SEQ Water Grid

    The SEQ Water Grid is our connected network of dams, water treatment plants, reservoirs, pump stations and pipelines. The grid allows us to move water around South East Queensland as needed. The Scenic Rim region is not currently connected to the SEQ Water Grid. This means water can only be moved into the Scenic Rim by truck.

    Connecting Beaudesert to the water grid will ensure we can continue to provide a safe, secure water supply to the Scenic Rim. Long term water reliability for the Scenic Rim will support ongoing economic development and population growth in the region.
