Work on the Selfs Point Sewer Transformation continues to make strong progress, with the project now more than 50% complete. This marks a major milestone in this once-in-a-generation upgrade that will help strengthen Hobart’s wastewater network and protect the River Derwent for future generations.

Since our last update, major construction activity has continued both at Selfs Point and along the pipeline route between Macquarie Point and New Town Bay.

Progress at Selfs Point

Construction at the new treatment facility site is advancing well.

Concrete works have now been completed for the project’s largest structure, the new bioreactor-membrane tank, which will play a key role in improving wastewater treatment performance.

Major pumps have also been installed. Once operational, these pumps will move flows equivalent to around 5.5 million average household toilet flushes every day.

To support construction at the site, more than 60,000 tonnes of quarry material, the equivalent of around 2,400 truckloads, have been delivered.

Pipeline progress

Significant progress has also been made along the 4.3-kilometre pipeline route, with more than 3 kilometres of new sewer pipeline now installed between Macquarie Point and Selfs Point.

Current works are focused on the Regatta Grounds car park and Queens Walk, where crews are installing the next section of pipeline that will connect with works completed last year through the Cornelian Bay Oval area.

We recognise these areas are important community links and thank residents and visitors for their patience while we complete these essential upgrades.

Investing in Tasmania’s future

The Selfs Point Sewer Transformation is helping protect the Derwent, replace ageing infrastructure and support the needs of a growing Hobart.

More broadly, TasWater has proposed investing $1.7 billion over the next four years through its Fifth Price and Service Plan to strengthen essential water and sewer services across Tasmania.

These investments will help protect our environment while delivering long-term benefits for communities across the state.

What’s next

In mid-March, works will progress toward the Tasman Highway, including installation of the pipeline across McVilly Drive.

To complete this work safely, McVilly Drive will be closed to all traffic during the following period:

Monday 16 March 2026, 7:00 am – Tuesday 31 March 2026, 5:00 pm

You can find more information about this closure, including access arrangements and detours, on the project page:
