The plant has treated sewage in Argoon Road since 1987 and can treat around 1.4 million litres a day. It serves thousands of homes and businesses in Healesville as well as homes, wineries and industry in the surrounding Yarra Valley area.

The upgraded treatment plant will be able to treat 2.5 million of litres of sewage a day. The bigger plant will be able to manage heavy rain and floodwater better. We’ll also upgrade the equipment and treatment processes. This will ensure the treatment plant continues to meet stringent environmental regulations and maintains and protects healthy waterways.

The upgraded plant will have more capacity to support homes and businesses in Healesville and surrounding areas into the future.

We've submitted our Planning Permit and Development Licence applications

We’ve now submitted our Planning Permit application to Yarra Ranges Council, and our Development Licence application to the Environment Protection Authority Victoria (EPA Victoria).

The feedback you gave us this year has helped shape these applications, particularly around odour and noise monitoring and management.

EPA Victoria and Yarra Ranges Council will review our Development Licence and planning permit applications, respectively.

We plan to start constructing the new facility in 2026 after we receive the relevant approvals and permits. We expect it will take around 2 years to build.

We invite you to review and give feedback on our applications

Yarra Ranges Council and EPA Victoria will advertise our applications as part of their public consultation processes. You’ll be able to review and give feedback on our applications by:

  • Searching for our Planning Permit application PDPER-2025-0180 on Yarra Ranges Council website.
  • Searching for our EPA Victoria Development Licence application APP047556 on Engage Victoria website.

Have your say May 2025

The local community gave us feedback about our plans to upgrade the treatment plant and concerns they want us to be aware of as we progress the project. The key themes we heard from your local community at our engagement pop-up sessions and discussions with neighbours are:

  • Concern about impacts to the visual amenity of the area and visibility of the upgraded plant.
  • Opportunities for early vegetation screening.
  • Making sure we control odour and continuously monitor air quality.
  • The potential for increased noise, odour or flood risk from the upgraded plant.
  • Concerns about increased and inappropriate development in Healesville.
  • The population size the planned upgrade of the plant will support.
  • The timeframe for future sewerage system connections in Healesville.
