Work to improve the quality of Launceston's biggest waterway has reached a new milestone, with construction of a giant storage tank at Ti-Tree Bend underway, following the recent completion of upgrades to the Margaret Street Pump Station and Western Rising Main.
The 10-megalitre concrete tank will be connected to the new pipeline under the Kanamaluka / Tamar Estuary riverbed – boosting the storage capacity of Launceston's combined sewage and stormwater system, and significantly reducing untreated overflows.
Ahead of construction, mass soil mixing works of more than 28,000 cubic metres of soil – the equivalent to filling 11 Olympic-sized swimming pools – were undertaken, along with the installation of 120 concrete piles to a depth of 20 metres.
With these essential ground improvement and foundation works completed, TasWater is now beginning construction of the new 10-megalitre covered storage facility and supporting infrastructure, with the project expected to be completed in 2026.
The project is supporting up to 80 jobs during construction, and includes the services of local Tasmanian contractors, One Earth Excavations.
It is part of the $140.7 million Tamar Estuary River Health Action Plan, with the Albanese Government providing $49 million, the Rockliff Government $47.5 million, TasWater $33.2 million, and the City of Launceston $11 million – an initiative of the $609.4 million Launceston City Deal.
