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. 

Community Update - 2 April 2019

Potential temporary increase in odour

Work on the plant has been progressing as planned and we are now finalising the transition of the plant into its upgraded operating mode.

An important part of the upgrade includes improving odour control at the plant. To complete this work we need to move larger than usual volumes of wastewater through the plant into the newly constructed sections. This may result in an increase in odour from the plant for a short period (48 hours or less).

We plan to complete this work during the week starting 8 April.
