Hobart sewer upgrade hits midway point

TasWater says a healthier Derwent is one step closer, with the Selfs Point Sewer Transformation project now more than 50% complete.

The year ahead will see the project move into its final stages, with key milestones scheduled for completion. The Macquarie Point Pumpstation, is now more than half complete, and will replace the existing Macquarie Point Sewerage Treatment Plant with a modern and reliable system.

Construction of the 4.3-kilometre sewer pipeline will continue through the Regatta Grounds car park and towards the Tasman Highway over the coming weeks.

In addition, the Selfs Point emergency outfall pipeline is on track for completion in early 2026, ensuring treated overflow wastewater is safely transferred offshore for improved environmental protection during periods of high rainfall.

TasWater General Manager Project Delivery, Tony Willmott said the project is one of the most significant infrastructure investments in TasWater’s history.

“Reaching the 50% mark is a major project milestone and is a reflection of the hard work happening on the ground every day,” Mr Willmott said.

“With our trusted partners UGL Limited and CPB Contractors, along with the local contracting market, TasWater is building a state-of-the-art treatment facility capable of processing up to 25 megalitres of wastewater daily, safeguarding the River Derwent while meeting Hobart’s future growth needs.

“To date we have delivered a number of major achievements on the project including 6,500 cubic metres of concrete poured at the Selfs Point site – which is enough to build foundations for more than 300 homes and the installation of more than 2,500 tonnes of reinforcing steel, stretching from Hobart to Launceston and back if laid end to end.

In addition to the ongoing works along the rear of the Botanical Gardens, , crews have recently installed 300 metres of pipeline through the Cornelian Bay Oval area, with backfilling now complete and grass seeding to follow. TasWater is committed to minimising disruption in this well-used community space while delivering essential upgrades.”

The project is being supported by the Tasmanian Government and due to be completed in late 2026.
