Woodman Point Wastewater Treatment Plant Upgrade

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 late 2019.

How will this impact the community?

An important part of the upgrade is improving odour control at the plant. To do this, we need to move larger than usual volumes of wastewater through the plant into the newly constructed sections. This may result in a temporary increase in odour from the plant (48 hours or less). We plan to complete this work during the week starting 8 April.
