TasWater has provided details of its Tolosa Park Dam Redevelopment Project. 

The Tolosa Park Dam Redevelopment Project is a partnership between TasWater and Glenorchy City Council, and is the first step towards completion of a vision outlined in the Glenorchy City Council’s Master Plan, developed through extensive consultation with Glenorchy’s communities on the future of this important asset. 

The project will involve employing a contractor for earthworks and landscaping that will remove most of the 20-metre-high dam wall and sculpt the area into a usable space.

Once the new grasslands and water features are established and ready, the fence around the site will be removed so the public can enjoy the new area.

The key features of this project will include:

  • creating a gently undulating site that includes level family-friendly areas

  • shapes that allow for drainage and overflow following large rain events, covered with topsoil to stabilise the new area with vegetation

  • a chain of lined wetland ponds, filled with water and appropriate plants

  • a series of level walking tracks

  • most of the dam wall will be removed and used to fill the site, but a small section will remain as a viewing platform and maintain the site’s heritage

  • the existing concrete bypass channel will not be changed

  • the existing masonry wall along the north-western edge will remain in place

  • the boundary fence will remain in place during construction until the new grasslands are well established.

TasWater expects to appoint a contractor for this project in the first half of 2023. This work will need to happen during the generally drier summer months of 2023-24, with an expected completion in mid-2024. A final schedule can only be determined once a contractor is appointed and will depend on weather for growing the new grasslands.
