The kanamaluka/Tamar estuary is a special landscape that connects our community. We appreciate its importance to Launceston and the wider community, which is why we are making investments today to ensure its health for future generations.
As part of the Tamar Estuary River Health Action Plan (TERHAP), we are delivering new sewerage infrastructure for the city to improve the health of kanamaluka/Tamar estuary and the environment that surrounds it.
The Ti-Tree Bend Sewage Treatment Plant Covered Storage Project will involve the construction of a new network storage tank that has two compartments, an overflow tank, and a balance tank, with a combined capacity of 10 megalitres.
The future flows to these new storage tanks will be transferred via the New Sewer Pipeline we are currently building 40 metres under the estuary riverbed between our Margaret Street Pump Station and the Ti-Tree Bend Sewage Treatment Plant.
Once completed, this new storage capacity will enable us to temporarily store and buffer any incoming flows from the combined Launceston sewer system before we then transfer these flows to the existing plant for the final phase of treatment.

Major construction works are well underway at our Ti Tree Bend Sewage Treatment Plant
We have started building the future new 10 megalitre covered storage tank, including reinforced concrete works. To date, we’ve poured nearly 300 cubic metres of concrete, to provide a flat and clean working platform for the concrete works. We have also completed the first slab pours, which will create the solid foundations for the walls and roof of the new tank.
During September we drilled almost 120 concrete piles into the ground, which will provide additional foundations for the new tank. The piles were drilled almost 20 metres deep and will support the tank by minimising settlement and anchoring the tank during rainfall and flood events.
The project has cut the piles down using a pile cropper to prepare the piles for connection to the new covered storage tank.
In October, we completed final major excavation works up to seven metres deep in preparation for the concrete works. These works, together with the extensive Mass Soil Mixing works that we completed mid-year, help ensure our excavations are safe, stable, and dry.
The project is expected to be completed during 2026.
The Tamar Estuary River Health Action Plan (TERHAP or the Plan) is an initiative of the Tamar Estuary Management Taskforce (TEMT) and the Launceston City Deal, to improve the health of kanamaluka/Tamar Estuary.
TERHAP is jointly funded by the Australian and Tasmanian governments, the City of Launceston and TasWater.
As part of the Tamar Estuary River Health Action Plan (TERHAP), we will be delivering new sewerage infrastructure to improve the health of kanamaluka/Tamar estuary.

Since creation, the palawa have lived here in lutruwita - Tasmania. Over 2,000 generations of Aboriginal families have cared for this Country, looking after its lands, seas, skies and waterways.
In the spirit of respect and gratitude, TasWater acknowledges the Tasmanian Aboriginal community as the traditional and ongoing custodians. We pay our respects to them, their culture and to elders past and present. We also acknowledge any Aboriginal and Torres Strait Islander people who are here with us today.
TasWater commits to working collaboratively and respectfully with the Tasmanian Aboriginal community to protect and sustain the precious resources on this ancient land for future generations.
