Swansea Dam

The interior of the Swansea Dam during construction, in April 2018.

The Swansea Dam is now fully repaired and functional, with a new clay liner on its inside surface. The remaining construction onsite to build a toe berm and roadworks is expected to be complete by March 2019.

The Swansea Dam was built in 2009 to improve water quality and security for the town, and to capture seasonal flows from the Meredith River. Unfortunately, seepage was detected downstream shortly after the dam opened in 2010. After TasWater assumed responsibility for the dam in 2013, we lowered the water level to maintain its safety and the Swan River continued to be Swansea's water source.

In 2017, Tasmanian Irrigation constructed its own pipeline adjacent to the Swansea Dam, and a series of agreements with Tasmanian Irrigation made it possible for us to secure a back up water supply for Swansea. This enabled TasWater to maintain the security of Swansea’s water supply, after the dam was drained for repair at the beginning of 2018.

The primary component of the repair has involved building a clay liner on the entire inside surface of the dam, to prevent seepage. TasWater has invested significantly in the construction of the clay liner and in quality control to ensure it is fit for purpose.
