Bunbury Wastewater Treatment Plant capacity increased after upgrade

The first stage of a $10.5 million project to upgrade the Bunbury Wastewater Treatment Plant is now complete.

The upgrades will ensure the plant has the capacity to safely process wastewater into the future as the population continues to grow in the region.

Stage one of the project has increased the treatment capacity of the plant from 11 million litres of wastewater a day to 13 million litres a day – equivalent to five Olympic-sized swimming pools.

Work on the treatment plant, located between Bunbury and Dalyellup, began late last year and the first stage was completed in November.

Stage two, which involves further minor upgrades to mechanical technology, will begin this month and will take about four months to complete.

Wastewater is 99.7 per cent water as it comes mostly from showers, baths and washing machines.
