Woodman Point Wastewater Treatment Plant Upgrade

Project goal:

To make sure the plant continues to support the growing population in the catchment area.

Delivery date:


The Woodman Point Wastewater Treatment Plant is the largest wastewater treatment plant in Western Australia.

It treats wastewater for a population of about 680,000 people living south of the Swan River in the Perth metro.

As the population in the catchment area continues to grow, additional treatment capacity is required at the plant.

The Woodman Point Wastewater Treatment Plant upgrade project will see the plant’s capacity increase to 180 million litres per day, accommodating a population of more than 900,000. It is expected to be completed by late 2019.

Letter from the Project Director

Last month we shared with you details of the work we were completing to repair the Woodman Point Wastewater Treatment Plant following an incident in late April.

This repair work is now finished, and the plant has returned, and will remain in its ‘interim operating mode’ for the next few months while we continue with the upgrade.

I appreciate there have been some days during the recent repairs when an odour has temporarily come from the plant, and I do apologise for any inconvenience this may have caused.

While the plant is in its interim operating mode, I do not expect odours to occur as part of the upgrade for many months, however I will be back in touch with the community in the lead up to any work that may result in temporary periods of odour.

I want to take this opportunity to thank you for your ongoing patience and support while we complete this important project, which is necessary to support future growth in Perth.

For more information about the upgrade, due for completion in 2019, visit watercorporation.com.au/woodmanpoint or if you have any questions, please phone Community Engagement Officer, Tarryn Truscott on 9420 3488 (during business hours) or email community.engagement@watercorporation.com.au.


The Department of Health informed Water Corporation on 13 June 2018 the precautionary advice previously issued for a one kilometre area at the end of the Cape Peron Ocean Outlet, could be lifted.

Extensive ocean monitoring and water quality sampling at the end of the outlet, four kilometres off the beach at Cape Peron, helped inform this decision, as the water quality in the exclusion zone is back to normal and safe for people to recreate and fish.

We again apologise for any inconvenience for ocean users in this area as a result of the precautionary advice being in place.
