The former Portland Gasworks site at 25 Glenelg Street is undergoing an important environmental restoration to remove historical pollution and make the land safe for potential future use.
AusNet has engaged Ventia, a highly experienced environmental remediation contractor, to carry out clean-up works between August 2025 and mid-2026.
This work is being delivered under strict EPA Victoria guidelines, with independent environmental consultants and an accredited auditor supervising the process.
Why does this work need to take place?
We aim to make the area cleaner and healthier by:
- Safely remove and dispose of polluted soil at licensed facilities
- Protect local water and environmental health
- Prepare the land for safe, future use
What’s involved
The remediation project will be completed in five stages:
October 2025 Construction Update
Key activities completed this month include:
• Excavation of smaller targeted areas
• Loading and transportation of excavated materials
• Installation of environmental controls
• Delivery of major machinery, including a crane and piling rig
We’re pleased to report that progress is tracking well, and we’re nearing completion of the support structures required for the upcoming deep excavation.
Managing impacts
While every effort will be made to reduce impacts on residents, businesses, and the local community, there may be times where disruptions are unavoidable.
Here’s what you can expect:
- Works will generally take place Monday to Friday, between 7am and 5pm. Some works on Saturday may be required from time to time
- Heavy vehicles will access the site via Glenelg Street
- Temporary structures, such as an Odour Control Enclosure and air filtration systems will be installed to manage dust and smells
- A Construction Environment Management Plan (CEMP) is in place to control noise, vibration, odour, dust, and stormwater
- Regular monitoring will ensure air quality and water levels remain within safe limits
- The site will be fenced, signed and secured to protect workers and the community
AusNet and Ventia are committed to keeping the community informed and involved throughout the project. Signage, regular updates, and community feedback opportunities will be available
