TasWater has completed a major upgrade of the Green Point sewage treatment plant as the utility advances $2 billion worth of works across the state.
Upgrades to the plant’s electrical and control systems have been completed, along with improvements to two anaerobic digesters, and the installation of a new biogas system.
TasWater project manager Derrick Clack said the project is critical to ensuring essential services for greater Hobart.
“As with all brownfield projects, the Green Point treatment plant still had to be in operation while the upgrade works took place,” he said.
“It can be quite challenging to have the plant run while construction works are underway, but the operations team worked seamlessly while we commissioned and integrated the new plant and equipment into the existing infrastructure.
“These system improvements ensure the treatment plant can continue to meet the needs of the growing Bridgewater community now and into the future.”
TasWater is also advancing upgrades to the Selfs Point sewage treatment plant, which includes installing Tasmania’s largest pump station at Macquarie Point, along with the Ti Tree Bend sewage treatment plant, where a new 10-megalitre storage tank has been installed and a pump station capped.
The Ti Tree Bend developments go hand-in-hand with the Tamar Estuary River Health Action Plan, which involves new sewage infrastructure being built to improve the health of the Kanamaluka/Tamar estuary.
Ultimately, TasWater is looking to resolve a range of legacy problems in a state that has 110 sewage treatment plants, which equates to having 38 per cent of the water and sewage treatment plants for two per cent of the Australian population.
Tasmania also has the highest drinking water leakage rate than any other state in Australia – something else TasWater is looking to rectify.
