Jandakot wastewater upgrades
Project goal:
We are upgrading the wastewater infrastructure within the City of Cockburn to cater for the growing community.
Status:
In construction
Delivery Date:
Late 2027
What's happening?
We are constructing new wastewater infrastructure to help cater for the continued growth in the City of Cockburn.
The infrastructure includes;
- A new 5.6km wastewater pipeline
- Upgrades to the existing Clementine Boulevard wastewater pump station
- Construction of a new 4.7m control tower on Elderberry Drive near South Lake Primary School
What is a 'hydraulic control point/control tower?'
The purpose of the control tower is to ensure the pipeline remains full of wastewater at all times as having air in the pipeline can lead to hydraulic pumping issues.
Where is this happening?
The wastewater pump station will be upgraded on Clementine Boulevard in Treeby. The new pipeline will be installed from Solomon Road in Treeby, through Jandakot, Cockburn Central, South Lake, and finishing on Osprey Drive. The hydraulic control point will be installed along Elderberry Drive in South Lake, at the corner of Hop Bush Park.
Map of the work area
Take a look at the project map to see the work area.
Why is this taking place?
The Jandakot area is currently experiencing high development growth, which requires new and upgraded infrastructure to service the growing community.
When is this taking place?
We are going into construction September 2026 in a staged approach, starting on Cutler Road, Jandakot. We anticipate construction will take around 15 months, finishing by late 2027.
How will this impact the community?
As with any construction activities there will be an increase in noise, dust and activity in the area. There will also be temporary impacts to roads, verges and pedestrian paths.
As the pipeline will be installed through the environmentally sensitive Little Rush Lake, we have worked closely with the Department of Biodiversity, Conservation and Attractions (DBCA), the City of Cockburn and our environmental team, to minimise any potential impact to the regional park during and after construction.
We will be tunnelling underneath the Kwinana Freeway, and working closely with the Public Transport Authority of WA and Main Roads to ensure the work is completed safely and efficiently.
We follow a thorough reinstatement process to ensure all impacted areas are replaced like for like, where practically possible. We will also work closely with the City of Cockburn and residents to ensure all reinstatements are carried out to an acceptable and high standard.
Verge trees
It is likely that some verge trees will need to be removed on Elderberry Drive, Tarndale Way and South Lake Drive to allow sufficient access to lay the pipe; however, all significant trees will be retained. We are working closely with the City of Cockburn on a reinstatement plan which will be implemented after construction work is complete.
What is happening?
Construction on the new wastewater pipeline will begin near the corner of Prinsep Road and Cutler Road in Jandakot. This section pipeline will be installed using a method called open trench excavation.
The open trench method allows the new pipe to be laid directly into the ground. Trenched areas will be fenced off and clearly signed.Where is this happening?
Works in this area will be completed in stages to minimise impacts on traffic, property access and the surrounding community.• Stage 1: Works will commence on the verge near 26 Cutler Road, Jandakot, close to the intersection of Prinsep Road and Cutler Road.
• Stage 2: Works will move into the Prinsep Road and Cutler Road intersection.
• Stage 3: Crews will then work within the northbound lane of Prinsep Road, between Imlah Court and the Prinsep Road and Cutler Road intersection.
• Stage 4: Works will then progress along Imlah Court towards Kwinana Freeway.
Please refer to the detour maps overleaf for more information.
When is this happening?
Works are scheduled to commence the week of Monday 21 September and be completed by mid-October, weather and site conditions permitting. Construction will progress sequentially through each stage as works are completed:• Stage 1: Mid September to early October
• Stage 2: Early October, for two days
• Stage 3: Early to mid October
• Stage 4: Mid October
The work will be completed during standard working hours, Monday to Friday, 7am to 5pm.
How will this work impact me?
During works, you may notice increased levels of noise, dust and vibrations. We will do everything we can to minimise these impacts during works. A staged traffic management approach will be implemented to reduce impacts on local roads (see detour maps in the Traffic detours tab).The majority of service locating work was successfully completed last year. However, we are still required to carry out service locating across three intersections. This work will be carried out at night to minimise impact on traffic.
• North Lake Road and Elderberry Drive
• Berrigan Drive and Elderberry Drive
• Solomon Road and Cutler Road
Work will take place across three nights between Sunday 19 January to Friday 31 January 2025 between 7pm and 3am.
Nearby residents will be notified via letter drop regarding which dates, within this period, night work will take place.
Stop/slow traffic management will be in place as required, please follow directions to ensure the safety of our crew and the community.
From Monday, 25 November 2024 to late December 2024 we will be conducting service locating along our proposed pipe alignment.
Service locating allows us to find underground utilities and pipes. We use vacuum trucks and trailers to drill holes and survey underground. The area is then backfilled and reinstated.
What to expect:
- Work will take place from 7am - 5:30pm Monday to Friday. Some night work may be required, but we will endeavour to keep it to a minimum.
- This work is not expected to impact any utility services in the area.
- Work will take place mainly within the verge along the pipeline route.
- You may notice an increase in noise and truck activity in the area.
- Temporary traffic management will be in place as required to direct vehicles, pedestrians and cyclists safely around the work area.
Thank you for your patience and understanding while this essential work takes place.
Frequently asked questions
What is the Jandakot wastewater upgrade project?
To cater for the continued growth in the City of Cockburn, Water Corporation is installing new wastewater infrastructure from Jandakot to Yangebup, which will be managed by authorised contractors Rob Carr and DM Civil.
The work includes a 5.6-kilometre underground pipeline that will be installed mostly via opencut trenching with some drilled sections to reduce disruption in busy areas. This new pipeline will deliver wastewater from the area to the Bibra Lake Main Sewer.
There will also be an upgrade of the existing Jandakot Clementine Boulevard wastewater pump station at the corner of Ginger Loop and Clementine Boulevard and a new 4.7m high discharge tower or hydraulic control point at the corner of Hop Bush Park on Elderberry Drive, South Lake.
All impacted areas will be reinstated.
Where will the pipeline go?
The wastewater pipeline starts at Cutler Road, Jandakot (at the intersection of Solomon Road) before travelling west under the freeway via tunnelling, through Cockburn Central and South Lakes and ends at Osprey Drive, Yangebup. The map below provides more detail.
The full map can be viewed on the Jandakot wastewater upgrades landing page.
Why do we need this pipeline?
Water Corporation is currently working on multiple infrastructure projects within the City of Cockburn to cater for its continued growth while sustainably managing WA’s water future.
Due to the high development growth in Banjup and Jandakot, a new wastewater pipeline and an upgrade of the Jandakot Clementine Boulevard Pump Station are required to deliver wastewater to the Bibra Lake Sewer Main. Without this work, there is an increased risk of wastewater overflows in the area.
How long will it be in construction?
The project will begin in September 2026 and will be broken into multiple stages, which take varying amounts of time to complete. We will notify nearby property owners and tenants before each stage begins so they can adequately prepare for any impacts.
We will also frequently update our website under the ‘Project updates’ tab so you can see what area of the pipeline is under construction.
The project is expected to be completed by early 2028.
How will the community be impacted by this work?
Most of the pipeline will be constructed by digging a trench, laying sections of pipe, then covering and restoring the ground above.
During construction you may notice some increased noise, vibration, dust, traffic detours and temporary fencing. We will manage these impacts carefully and ensure you have access to your property.
We will work closely with residents and businesses whose property we may impact, and ensure we carefully restore any affected areas.
Who is doing the construction?
Water Corporation has contracted Rob Carr and DM Civil to construct the pipeline.
For enquiries on this project, please contact the project’s Community Liaison Officer Gabe Denemark on CS02964-communications@dmcivil.com.au or 0492 359 240.
For onsite enquiries or concerns requiring immediate action, please contact Project Manager Adam Shanley via adam.shanley@robcarr.com.au or 0488 174 689. .
How will the community be impacted by this work?
The main environmental impact assessed for the installation of the pipeline is the clearing of native vegetation, which is limited to works east of Little Rush Lake and within Bush Forever site 256, and some planted verge trees maintained by the City of Cockburn.
Fauna will be protected via a pre-clearing inspection by a qualified fauna spotter or environmental specialist. If fauna is spotted during clearing, works will cease until the animal is safely relocated in accordance with approved fauna-handling protocols.
We are also working closely with the City of Cockburn and WA Wildlife to identify Oblong Turtle nesting sites within the Beeliar Nature Reserve and all site inductions will include information on the turtles and other local wildlife.
We will have a suitably qualified and licensed Fauna Handler available for the duration of the project, who will be responsible for the safe relocation of any fauna requiring removal from the construction area.
Once the project finishes, the project will provide funds to the City of Cockburn to reinstate the verge trees.
Is there any support available for my business?
We understand that construction work can impact small businesses. We work with the local government and Small Business Development to support affected businesses during our essential work. We encourage businesses to get in touch and discuss how we can best help.
