Woodman Point Wastewater Treatment Plant upgrade

back to current projects

Project goal:

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


In construction

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. 

Public notice - Additional temporary odour management installed - March to April 2018

Additional temporary odour management measures have been installed at the Woodman Pt wastewater treatment plant to support upgrade work currently underway.

We are converting the plant’s operations to a temporary state to allow us to complete improvements on key parts of the plant. This process is expected to take 4-6 weeks and will be complete in April.

We apologise to members of the community that have been impacted by odour while we complete the upgrade project, which will increase plant capacity and includes installation of additional permanent odour control measures.

Any enquiries should be directed to Water Corporation’s Faults, Emergencies and Security line on 13 13 75
