Yanchep water and wastewater upgrades
Project goal:
To cater for new residential developments in northern Yanchep, we plan to construct 1.6km of water pipeline and a new wastewater pipeline.
Status:
Commencing soon
Delivery Date:
April 2026 – mid 2027
What's happening?
​To help ensure a reliable water supply and wastewater
system, we are planning to upgrade the water supply and wastewater
infrastructure in Yanchep. We will construct approximately 1.6 km
of new water pipeline main along the east side of Marmion Avenue in the road
reserve, from Yanchep Beach Rd to Botanic Boulevard. The proposed pipeline will
connect to an existing pipeline near the intersection of Marmion Avenue and
Yanchep Beach Road. We will simultaneously construct a new 800m wastewater pipeline
along Marmion Avenue.
When is this happening?
At this stage, work is expected to commence in April 2026 and will take approximately 12 months to complete.
Most of the work will be completed Monday to Friday between 7am and 5pm. We will notify you beforehand if nightworks or weekend works are required..
How will this impact me?
Residents may notice noise, dust, and increased vehicle activity in the area whilst we complete this work. As with any construction activities there may be an increase in noise and dust in the area. We are working to minimise the impacts of construction on residents where possible.
Traffic management will be in place as required to direct vehicles, pedestrians, and cyclists safely around the work area. Construction areas will be fenced; however, some footpaths may be impacted. 
We will maintain safe access to Splendid Park.
We thank you for your understanding and cooperation whilst this essential work takes place.
