Martin to Wungong water pipeline

What's happening?

We’re planning a 12 km underground water pipeline that will follow existing local roads. This pipeline will support future drinking water supplies by helping move and store water between Canning Dam and Wungong Dam.

This work is part of a broader program to make the Perth water network stronger and able to handle future demand.

Why is this happening?

The new pipeline will help move large volumes of water between Canning Dam in Ashendon and Wungong Dam in Bedfordale. This will support water security across the south‑east metro area and provide important back‑up for the Belmont and Nicholson pump stations.

It will also:

• strengthen the local water supply
• help the network during high‑demand periods
• support future desalinated water entering the system

When is this happening?

Planning and investigations will continue throughout 2026.

Construction is expected to begin in 2027/28. Work will be completed in stages to reduce disruption to the community.

We expect the entire pipeline to be complete around 2030.

Where is this happening?

The proposed pipeline route currently includes: Connell Avenue, Pries Park Road, Cockram Road, Clifton Street, Orlando Street, Ottoway Street, Streich Avenue, Armadale Road, Abbey Road, Green Avenue, Wungong Road, Hobbs Drive and South Western Highway. We’re currently finalising the route with the City of Armadale and Gosnells as environmental and heritage checks continue.

 

How will this impact me?

Most construction will use open‑trench methods. In some areas, we’ll use tunnelling under major roads such as Albany Highway, River Drive and South Western Highway to reduce impacts.

When work is underway, you may notice:
- more activity in the street
- temporary noise and dust, both of which will be monitored and controlled using suppression measures
- traffic changes or short detours

Traffic management will be in place to help people move safely around work areas.

Some work may be needed in residential verges. If this affects your property, we’ll contact you ahead of time to explain what to expect.
 

Protecting the environment

We know trees and natural areas are important to the community. To reduce environmental impacts, we will:

- work with arborists and local governments
- avoid removing trees wherever possible
- use construction methods that protect tree roots and minimise any impacts
- provide offsets where tree removal can’t be avoided
