Warrnambool sewage treatment upgrade – Have your say

Environment Protection Authority Victoria (EPA) is calling for public comment on a proposed sewage treatment plant upgrade for Warrnambool.

Wannon Water has applied for an EPA Works Approval for the upgrade of the plant at Elliot St, Warrnambool.

The proposed plant upgrade is designed to increase its capacity to meet the city’s demand for sewage and wastewater treatment until 2040.

The upgrade would rely on the same technology currently in use at the plant, with the addition of a new inlet screening facility and two new aeration tanks.

You can find the application documents and have the opportunity to lodge a submission on the Engage Victoria website, here: https://engage.vic.gov.au/epa-works-approvals/wannon-water

In assessing the Works Approval application, EPA considers any potential effects on climate change, groundwater, surface water, soil, noise, odour, air quality, waste and any potential hazards to people’s health.

EPA encourages members of the public to ask any questions about the Works Approval process or Wannon Water’s proposal via the link on the Engage Vic website.

Submissions on this Works Approval application are open until 17 June 2020, and EPA expects to announce its decision in August.


EPA issues Works Approvals under the Environment Protection Act 1970. They are required for any industrial and waste management activities that have the potential for significant environmental impact.

Where a Works Approval is granted, it includes specific environmental conditions the company must meet for the project to go ahead.
