What's happening?

To secure Onslow's long-term water future, Water Corporation plans to construct a seawater desalination plant in Onslow. The proposed plant will include:

  • Reverse osmosis seawater desalination plant
  • Intake and outfall pipeline(s) at Beadon Bay
  • Water tank and pumping station
  • A 2.9 kilometre below-ground pipeline to tanks, where the water will be connected to Onslow's
    water supply

Where is this happening?

The proposed facility will be built on land north of Beadon Creek Road in Onslow. The intake and outfall pipeline(s) will extend into Beadon Bay.

Why is this work taking place?

An additional water source of 1.5 million litres per day is required to meet Onslow's demand for the next 20 years. The proposed seawater desalination plant in Onslow will result in the town having an additional source of water that is climate independent.

When is this happening?

Construction is expected to be completed by the end of 2024.

How will this impact the community?

  • The facility is very small compared with similar proposed desalination plants and is being designed to minimise environmental impacts.
  • Construction work can have local impacts, including noise, dust, traffic management and vibration. Before we start work in an area, we notify the surrounding community.
