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:
December 2025 Construction Update
Key activities underway this month include:
- Completion of the OCE assembly and installation of the Emissions Control System (ECS) to improve containment and air quality.
- Commencement of the deep excavation within the OCE, supported by water treatment plant operations to manage water from excavations.
- Ongoing transportation of soil off-site for safe disposal, with increased truck movements managed within approved haulage routes and hours.
- Site shutdown over the Christmas holiday period.
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
