TasWater is planning improvements for the drinking water supply for customers in the communities of Devonport, Latrobe, Forth, Turners Beach, Gawler, Ulverstone, Leven, Penguin, Port Sorell and Shearwater.

This program has been highlighted as a top priority in TasWater’s Long Term Strategic Plan as it will improve and extend the capacity of existing treatment infrastructure and provides flexibility to consolidate water sources and infrastructure in the future.

TasWater is planning improvements for the drinking water supply for customers in the communities of Devonport, Latrobe, Forth, Turners Beach, Gawler, Ulverstone, Leven, Penguin, Port Sorell and Shearwater.

This program has been highlighted as a top priority in TasWater’s Long Term Strategic Plan as it will improve and extend the capacity of existing treatment infrastructure and provides flexibility to consolidate water sources and infrastructure in the future.

TasWater will be seeking an increase to our existing Water Licence for the Forth and Leven Rivers as part of the North West Water supply strategy. This strategy was developed to ensure the water supply is sufficient to meet demand for future growth in these areas and continues to meet drinking water quality guidelines.

We have made a commitment to the community and to the Office of the Tasmanian Economic Regulator to ensure all our water treatment plants and water supply systems remain safe and secure and risks are managed properly. This strategy will make sure we can keep that commitment.

The strategy for the North West Water Supply System involves the interconnection of three systems in the North West. These are:

  • The Forth Water Supply System (which supplies water to communities as far west as Forth, Leith and Devonport, east to Port Sorrell and south to Latrobe)
  • The Gawler Water Supply System (West Ulverstone, Ulverstone, Gawler and Turners Beach)
  • The Penguin Water Supply System (Penguin)

This will involve:

  • Major upgrades to the Forth Water Treatment Plant, including increase to the raw water winter allocation from the Forth River
  • Major upgrades to the Leven (Whitehills) Water Treatment Plant, including increases to the raw water allocations in summer and winter from the Leven River
  • The construction of a new trunk main between the Gawler (Ulverstone) water supply network and the Leven Water Treatment Plant
  • The decommissioning of the Gawler Water Treatment Plant

The strategy ensures improved drinking water safety and water security and is designed to accommodate projected demand from all towns in the region for the next 30 years.
