Project goal:

To ensure the Woodman Point Wastewater Treatment plant continues to support the growing population in the catchment area.

Delivery Date:

Mid 2020

What's happening?

We’re upgrading WA’s largest wastewater treatment plant, the Woodman Point Wastewater Treatment Plant, to increase capacity to 180 million litres per day, which will allow it to service a population of more than 900,000 residents.

Where is this happening?

At the Woodman Point Wastewater Treatment Plant in Munster.

Why is this work taking place?

The plant currently treats wastewater for a population of about 680,000 living south of the river in the Perth metro area. But as the population in the catchment area continues to grow, additional capacity is required at the plant. These upgrades will increase capacity to accommodate for the area’s growing population.

When is this happening?

Work on the plant has been progressing as planned and we are now finalising the transition of the plant into its upgraded operating mode. It’s expected to be fully transitioned by Mid 2020.

How will this impact the community?

An important part of the upgrade included improving odour control at the plant and new equipment to achieve this is now fully operational. However, over the coming weeks, planned maintenance is required on equipment that controls the release of gasses from the plant. Although this is not part of the upgraded odour control system, maintenance on this equipment may result in an increase in odour from the plant. We plan to undertake this work during September for around 3 weeks.

How can I stay informed about the project?

Community Reference Group

The Woodman Point Wastewater Treatment Plant Community Reference Group is a dedicated volunteer group that represents community members living in close proximity to the plant. The group is independently chaired and meets regularly to provide community insight and feedback to inform our operations. If you would like more information, or to contact the group, please email
