Yokine to Belmont Trunk Main Upgrade
Project goal:
We are upgrading the 10.2km Yokine to Belmont water pipeline.
Status:
In progress.
Delivery Date:
Mid-2027.
What’s happening?
Our Yokine to Belmont water main is a 10.2-kilometre pipeline that delivers water from the Mt Yokine Reservoir through Dianella, Bedford, Bayswater, Ascot and Belmont to the Belmont Pump Station.
To cater for future growth and demand, we will be upgrading the pipeline over a staged approach from now until mid 2027.
Why is this happening?
The Yokine to Belmont water main will support Perth's next major water source, the Alkimos Seawater Desalination Plant, and the Eglinton Groundwater Scheme (starting in 2028). The water main will be 70 years old by 2028 and requires some minor upgrades to optimise reliability and operability for these new demands.
When is this happening?
The upgrades will be scheduled over four stages to minimise impacts on surrounding communities and work with asset availability windows. These windows include September to October 2025, May and September 2026, and May 2027.
Where is this happening?
Please see the ‘Work Areas’ tab for scheduled locations.
How will this impact the community?
Nearby residents may notice some more activity than usual, noise and dust during the works. We plan to be in each work site for only three to five days before moving to the next one. If required, traffic management will be in place to direct people around the work area.
Some work sites will be within residential verges. If the Contractor is working in your verge, we will contact you ahead of time to discuss the work.
The upcoming stage includes three localised work areas in the road and verge to access and upgrade this section of the pipeline in the City of Stirling.
Upgrade works will begin on 12 October and expected to be completed by 27 October.
Prior to the upgrade work, early service investigation work will take place between 5 October and 11 October from 9am to 2pm only. This will help identify and locate existing underground services to support the safe and efficient delivery of the pipeline upgrade.
Localised traffic management will be in place throughout the work to keep the community and workers safe. The area will be safely fenced off to the general public and we will work closely with the nearby residents to address any concerns.
