Civil Hydropower & Dams

 Fast Facts

  • 47m-high Roller Compacted Concrete (RCC) x 180m wide dam wall 
  • 1,200m of curtain wall drilling and grouting 
  • 85,000m3 of RCC and 225,000t of rock produced from onsite quarry 
  • Approximately 130,000 m3 of earth moved 

The project was awarded the Civil Contractors' Federation Earth Award for Construction Excellence in 2008 and the Concrete Institute of Australia 2009 Award for Excellence in Concrete - Engineering Projects Category. 

The project was a Tasmanian State Government initiative developed to provide irrigation water to the surrounding Meander Valley community with yield from the dam expected to be 24,000ML/year. The stored water would also be used to produce electricity with a mini-hydro power station to be constructed at the toe of the dam. 

Due to the pristine location, many environmental challenges had to be met. These included maintaining quality drinking water for the towns of Meander and Deloraine downstream from the construction site.  

Every possible precaution was taken including implementing state of the art clearing practices and stripping practices below-river-level construction.  

Now complete, the dam provides irrigation and environmental flows boosting productively in the region by approximately $38 million per annum.  

The scope of works for the project included:

  • Design and construction of a roller-compacted concrete (RCC) dam, intake tower and outlet works
  • Design and construction of an access road to the dam site and mini-hydro station and relocation of roads inundated by the reservoir, including a crossing over the Meander River
  • Protection and rejuvenation of endangered wildlife and fauna in the surrounding areas
  • Delivery of improved water and irrigation systems to farms and towns within the region.
