Phillip Island and San Remo population is growing and we are growing with it

We won’t take risks with your wastewater and the existing capacity of the plant will not meet future projected demand by 2021. A new 24m diameter clarifier will be constructed, along with major upgrades, allowing for future capacity up to 2036.

Project update

1 September 2021

The project remains on track to be completed by the end of 2021. Wet weather encountered during September and early October combined with  impacts associated with COVID-19 have caused delays in materials supply and human resources availability. Despite the challenges, we are confident that the new clarifier will be commissioned in time for the peak holiday season.
