    South West Pipeline | Email Update | April 2021

    Project update

    Seqwater has recently appointed Comdain Infrastructure to design and construct the 27-kilometre South West Pipeline. The pipeline will connect Beaudesert to the SEQ Water Grid and ensure a reliable long-term water supply for the Scenic Rim by making it easier to move water into the region when needed.

    The pipeline is the second stage of the Beaudesert Water Supply Upgrade, the long-term water supply solution for the Scenic Rim, supporting continued population and economic growth.

    The bulk water pipeline includes a three-kilometre section which will connect the Flagstone development area and the SEQ Water Grid pipeline network.  A further 24-kilometre bulk water pipeline will be constructed to deliver water to the recently completed Helen St Storage Reservoirs in Beaudesert.

    The new pipeline will be predominantly within existing rural road reserve and is not expected to significantly impact on farms or businesses along the proposed alignment.

    Early investigative works will commence this month to provide our designers with additional information for the pipeline design.

    Construction of the pipeline is on track for commencement from mid - 2021.

    Early works

    Comdain has commenced early works for the pipeline. These early investigative works include geotechnical borehole drilling, service location and potholing.  Early investigative works may also include aerial and ground surveying. Comdain started early investigative work at the most northerly point of the pipeline and are working south  over a number of weeks.

    The early works are expected to by completed by May, subject to weather and other unforseen circumstances. Comdain's work hours are from 7am until 5pm, Monday to Friday. 

    The South West Pipeline will run from Bushman Drive in the North to Beaudesert in the South.  It will be contained within the road reserves of Bushland Road, Dennis Road, Cedar Grove Road, Cedar Pocket Road, Undullah Road, Brooklands Road, Allan Creek Road, Bromelton House Road and road reserves east of the South Logan River crossing.

    Who is Comdain?

    On 19 March 2021, Seqwater announced Comdain Infrastructure as the successful design and construction contractor for the South West Pipeline. Comdain is a national leader in delivering critical gas and water services. Comdain are Australian owned and were established in 1962. 

    Over the next 18 months, Comdain and Seqwater (The Project Team) will be working together to design and construct the pipeline. The Project Team are committed to engaging with the community throughout this process. 

    Comdain will work directly with any impacted stakeholders, and adjacent neighbours may receive direct work notifications from time to time regarding construction impacts.

    The South West Pipeline will be approximate 27 kilometres, connecting Beaudesert to the SEQ Water Grid

    Construction contractor announced for South West Pipeline Project

    A major milestone has been reached for the South West Pipeline project, with Seqwater recently appointing the construction contractor.

    The major water pipeline project to connect Beaudesert to the SEQ Water Grid is on track to start this year, creating up to 100 construction jobs.

    Seqwater recently appointed Comdain Infrastructure to design and construct the 27-kilometre South West Pipeline which will take up to 18 months to complete.

    Seqwater Chief Executive Officer, Neil Brennan, said the $95 million project was on track and construction would begin in mid-2021.

    “Almost 90% of the jobs for the construction of the pipeline will be taken up by local tradespeople, while the remainder will go to workers from Queensland and other states,” Mr Brennan said.

    “The pipeline is the second stage of the Beaudesert Water Supply Upgrade, the long-term water supply solution for the Scenic Rim, supporting continued population and economic growth.”

    Mr Brennan said connecting Beaudesert to the SEQ Water Grid will make it easier to move water into the growing region when needed.

    “The existing Beaudesert Water Treatment Plant was built to serve a small town at the centre of a farming and grazing community.

    “Since then, the population of Beaudesert has grown, and the town has transformed into a significant regional hub.”

    The bulk water pipeline includes a three-kilometre section which will connect the site to the Flagstone development area and the SEQ Water Grid pipeline network.

    A further 24-kilometre bulk water pipeline will be constructed to deliver water to the recently completed Helen St Storage Reservoirs in Beaudesert.

    The new pipeline will be predominantly within an existing rural road reserve and is not expected to significantly impact on farms or businesses along the proposed alignment.

    South West Pipeline project update

    The Queensland Government announced funding for construction of the South West Pipeline on 10 March 2020. Seqwater is now in the process of sourcing a suitable contractor for delivery of the pipeline. Construction will begin in 2021 and is expected to be completed in 2022.

    In the next few months you can expect:

    • Contractors undertaking site inspections and additional investigations
    • Engagement with adjacent property owners about anticipated impacts.

    Most of the South West Pipeline will be built in State or Local Government road reserves. It will also pass through land owned by either Seqwater or state government agencies. Seqwater has already consulted the small number of affected property owners.

    Minister announces water pipeline to Beaudesert

    Work will start within months on a $95 million pipeline, creating up to 100 jobs, and delivering water security for decades for Beaudesert households, business and industry.

    “This pipeline will connect Beaudesert to the rest of the SEQ water grid’s dams and water storages, which will provide local householders and businesses with a more secure water supply into the future,” he said.

    “Importantly, water security will give potential new business and industry confidence that they can grow their businesses in the area and create jobs – particularly in the Bromelton state development area.”

    The $95 million, 27 km pipeline will connect the two recently-built reservoirs at the existing Beaudesert water treatment plant - and to the SEQ water grid – by 2022.

    Dr Lynham said once connected to the pipeline, the local community would have access to up to about 10 megalitres daily – more than double what was currently available.

    “This is fantastic news for the local community who can have confidence that major infrastructure projects are being delivered to improve water security for our communities,” he said.

    Pipeline tenders will be shortlisted next month, with a design and construction tender awarded later this year.

    Construction will start in 2021.

    Seqwater Chief Executive Officer Neil Brennan said the new reservoirs at Beaudesert provided further water storage and security in the interim until the pipeline was completed and connected.

    “The new reservoirs are expected to be fully operational by the middle of the year, providing more than 5 million litres of storage capacity,” he said.

    “They will provide about 10 times more storage capacity at the plant to further bolster Beaudesert’s water supply.

    “Connecting the Scenic Rim to the Grid will safeguard the region’s water security for the next 30 years.

    “The new pipeline will be predominantly within an existing rural road reserve and is not expected to impact on farms or businesses along the proposed alignment.”

    The last new community to join the water grid was more than 100,000 Moreton Bay residents and businesses, who joined up two years ago via a pipeline to the Boundary Road Reservoir.

    Beaudesert Storage Upgrade - Start of Construction

    Work is about to start on the construction of two concrete storage reservoirs next to the Beaudesert Water Treatment Plant on Helen Street.

    This is the first stage of the Beaudesert Water Supply Upgrade and will improve the reliability of water supply in Beaudesert. The reservoirs will store treated drinking water which can be used during high demand periods, maintenance work or other network shortages.

    The new storage reservoirs will be connected to the SEQ Water Grid in 2021. Long term water supply reliability will support the continued growth of the region.

    Key facts:

    • Each reservoir will be roughly 8.5m high and 26m across
    • Total treated drinking water storage of 5.1ML (million liters)
    • Construction expected to be completed early 2020.

    What to expect:

    During the construction period residents should expect:

    • Increased traffic, including trucks, on local roads
    • Most traffic will access Helen Street via Short Street (near the council building) / from the northern end (near the intersection with the Beaudesert Bypass)
    • Construction work between the hours of 7am and 5pm on weekdays and between 7.30am and 2pm on Saturdays when required
    • Minor disturbances associated with construction work, such as noise and dust
    • No changes to Seqwater operations at the Beaudesert Water Treatment Plant. Your water supply will not be affected by these works
    • Construction is expected to be completed early 2020.

    More about the Beaudesert Water Supply Upgrade:

    As the population and economy of Beaudesert 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 Beaudesert Water Supply Upgrade includes three stages:

    1. Upgrades to the Beaudesert Water Treatment Plant, including 5.1 ML of additional water storage.
    2. The South West Pipeline, a 27 km bulk water pipeline connecting Beaudesert to the SEQ Water Grid.
    3. The first stage of a new Wyaralong Water Treatment Plant adjacent to the Cedar Grove Weir.

    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.

    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 at Cedar Grove Weir and the SEQ Water Grid.

    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

    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 Water Treatment Plants.

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

    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.

    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.
