Project Overview Video
What's this project all about?
As part of TasWater’s commitment to investing in new and improved sewerage infrastructure to cater for Hobart’s future growth, we are delivering one of our most significant projects to date.
This project combines the following 3 separate, but interconnected projects:
- Selfs Point Sewage Treatment Plant upgrade, near New Town Bay
- Macquarie Point to Selfs Point pipeline
- New Macquarie Point Sewage Pump Station
Once we have completed these works, we will begin decommissioning the existing Macquarie Point Sewage Treatment Plant.
The existing Selfs Point Sewage Treatment Plant was built in 1972 to support the treatment of Hobart’s wastewater. The plant currently treats around nine megalitres of wastewater from Hobart suburbs including Lenah Valley, New Town, Mount Stuart, Sandy Bay, Dynnyrne, Tolmans Hill, Mount Nelson, and Taroona. That’s approximately 110,000 average baths a day!
The expansion and upgrading of the existing plant, combined with the future decommissioning of the Macquarie Point Sewage Treatment Plant, will deliver improved environmental outcomes and the new state-of-the-art facilities and treatment technologies will enable us to treat up to 25 megalitres of Hobart’s wastewater per day.
Preparation for the decommissioning of the existing Macquarie Point Sewage Treatment Plant and construction of a more compact state-of-the-art pump station at Macquarie Point will be undertaken while we upgrade and expand the existing Selfs Point Sewage Treatment Plant.
The Macquarie Point Sewage Treatment Plant currently treats wastewater from residential, business, and light industrial customers within North Hobart, West Hobart, Glebe, South Hobart, Battery Point and the Hobart Central Business District (CBD).
As part of this transformative project, we will be building a new 4.3 kilometre pipeline to connect the new pump station at Macquarie Point and the future Selfs Point Sewage Treatment Plant at New Town Bay.
By streamlining the operation of these two plants into a single modern facility, we will help improve marine health by removing tonnes of nitrogen and phosphorus from the Derwent River every year.Updates

Construction of the new sewer pipeline will commence in early 2025.
We will be working in sections to minimise disruptions where possible and we will ensure any changes to traffic and pedestrian access is communicated well in advance.
