The Subiaco wastewater treatment plant is the third largest of its kind in WA.

The upgrade project will boost plant capacity to up to 67 million litres a day and includes upgrades to existing treatment facilities, including new inlet works, replacement of secondary treatment components and modifications to the plant’s power supply.

The works are part of a staged approach to increase the plant’s capacity to treat additional wastewater to make sure it can continue to support the growing population in Perth, Scarborough and Fremantle, including the CBD.
