Raymond Terrace Wastewater Treatment Works upgrade

We’re upgrading Raymond Terrace Wastewater Treatment Works to provide for future growth in the area and improve the quality of the treated effluent discharged from the site.


Location: Elizabeth Street, Raymond Terrace

Project Duration: 2023 to 2024


The Raymond Terrace Wastewater Treatment Works serves the communities of Raymond Terrace, Medowie and some parts of Heatherbrae.

It currently treats 6.4 megalitres per day and can handle wastewater from a population of up to 35,000 people.

The upgrade of the treatment works will update treatment processes and the overall treated wastewater quality will improve. It will also ensure the plant caters for population growth.

All efforts will be made to minimise inconvenience to the community during construction.

Our lead contractor for this project is Service Stream Utilities.

Environmental assessment

As part of the planning process, we completed an environmental assessment known as a Review of Environmental Factors (REF) for the proposed works, and it can be viewed below.
