As part of our vision to go beyond water for strong communities, we’re committed to being bold in our work to care for and protect the environment. This commitment is reflected in our day-to-day work and is an important factor when we plan and undertake many of our projects.

One of those projects is a major upgrade of the Warrnambool Sewage Treatment Plant. The project is designed to cater for population, business and industry growth while continuing to protect public health and the environment.

The plant, located near Thunder Point in Warrnambool, treats sewage and trade waste from the city as well as Allansford and Koroit by removing physical, chemical and biological contaminants. The aim is to produce treated effluent that is suitable to discharge to the ocean according to the Environment Protection Act 2017 and site-specific discharge licence requirements.

The $85 million upgrade project will provide additional capacity to help manage the sewage and trade waste. It will also improve the quality of treated effluent discharged into the ocean. For example, improving the inlet screens and adding chemical dosing and UV technology will improve solids removal, reduce nutrient levels and disinfect the effluent, providing an additional layer of protection for the environment and public health.

In parallel with the upgrade project, we need to consider our community's long-term expectations on how we should manage treated effluent in the future. There are general concerns worldwide about the increasing impact that all sewage outfalls are having on the marine environment and the need to further consider biodiversity impacts and human health concerns. There are also growing calls for effluent to be treated to a safer standard and reused for beneficial purposes, supporting adaptation to climate change.

There are a number of options available to us and we have to decide which best serves the community and our stakeholders. That's why we're developing an Effluent Management Strategy.

We're seeking feedback from our customers and the community about what you value about Shelly Beach & Thunder Point as well as how you use the area. Please tell us what you think!
