    $40million upgrade of Wellington Dam

    The State Government has awarded a $40million alliance contract to bring the 70-year-old Wellington Dam into line with today’s engineering standards.


    Work would commence shortly on the project and form part of the Water Corporation’s ongoing State-wide Dam Remedial Works Program.


    The successful contractor, known as the Wellington Dam Alliance, combines the expertise of Leighton Contractors, AECOM, Hydro Tasmania and Structural System Limited working with the corporation.


    Water Minister Graham Jacobs said the project would take about two years to complete and was expected to contribute more than $5million to the local South-West economy.


    “The project will provide opportunities for local contractors, material suppliers, accommodation providers and job seekers in Collie and the broader South-West region,” Dr Jacobs said.


    “This will be a great boost for the local economy at a time when it is most welcomed and Leighton Contractors have started advertising locally for various positions.  


    “The net result will be the upkeep of an important State asset and another boost for local workers and businesses.”


    The Minister said a series of high-tensile steel cables would be installed vertically through the wall into the bedrock below to enhance the dam’s stability.


    “This is a commonly used approach for big dams like Wellington,” he said.


    “An operations bridge will be built along the crest of the dam to provide access to install the steel cables and enable future maintenance and monitoring.”


    Dr Jacobs said the project would not impact the spectacle created when the dam overflowed.


    “The storage capacity, height and basic design of the dam will remain essentially unchanged and overflows will occur in very wet years as we have seen in the past,” he said.


    The Water Corporation had investigated the concept of making the maintenance bridge accessible to pedestrians after the works had been completed.  However, following a detailed design and planning review it was now expected that to ensure public safety the bridge would be accessible only for operational purposes.


    Public access around the dam would be limited while the works take place, however, viewing would remain from the existing lookout and access to the Wellington Dam Cafe maintained.
