Fairbairn Dam Improvement Project
SunWater is undertaking the Fairbairn Dam Improvement Project to ensure the long-term viability of the dam in line with current design standards. Click here to read more about SunWater’s Dam Improvement Program.
The Fairbairn Dam Improvement Project (Stage 1 and Stage 2) is being undertaken after routine inspections detected the original spillway drainage system was no longer functioning efficiently.
Stage 3 works were added during a comprehensive dam risk assessment in December 2017 to improve long-term viability of the dam sidewalls.
Improvement works will ensure the dam can continue to function as designed.
Stage 1 works included:
- the modification of drain outlets
- the repair and replacement of blocked drains
- the replacement of the steel anchors
- the filling of any voids under the concrete slabs of the spillway
the construction of a mass reinforced concrete overlay to accommodate the steel anchors.
Stage 2 works include the same activities undertaken as Stage 1, but undertaken on a different section of the spillway.
Stage 3 works will include:
- the staged removal of original sidewall panels
- installation of new reinforced panels with solid foundations to facilitate installation of a new gravity wall
- construction of a new gravity wall which will help channel future outflows and relieve sidewall pressure.
Stage 1 works started in April 2016 and were completed in December 2016.
Stage 2 works started in April 2017 and are scheduled for completion in late 2020, weather permitting.
Stage 3 works started in mid-2018 and are scheduled for completion by late 2020, weather permitting.
Fairbairn Dam is approximately 17 kilometres south-west of Emerald and 270 kilometres west of Rockhampton in Central Queensland.
