Major works complete on Fairbairn Dam spillway
23 Dec 2016
The first stage of work to enhance the safety of Queensland’s second largest dam was completed this week as part of SunWater’s Fairbairn Dam Spillway Safety Improvement Project.
More than 380 steel anchors were installed, 1850 cubic metres of concrete poured and almost 400 metres of drainage were replaced to further strengthen the lower section of the spillway structure.
SunWater Executive General Manager, Asset Strategy and Delivery, Alex Fisher said the work was completed in time for the summer wet season.
“The first stage of the project has been completed and will significantly increase the safety and efficiency of the spillway in managing extreme rainfall events,” said Ms Fisher.
“Concrete was poured using the slip form method, allowing a continuous pour that results in a structure with superior performance and durability by reducing the number of construction joins.
A second stage of spillway improvement works will commence on Fairbairn Dam in 2017 and is expected to be undertaken over two years.
“The next stage of the project will involve the same type of works as the first stage; however the focus will be on the remaining sections of the spillway,” she said.
Both stages of the project are part of SunWater’s ongoing Dam Safety Improvement Program.
The Program involves regular detailed assessments and improvement works for SunWater’s 19 dams, which includes a 20 year program of improvement works to maintain the highest level of safety.
Fairbairn Dam is located approximately 17km south-west of Emerald in Central Queensland and services the region’s diverse resource and agricultural sectors, including the burgeoning cotton industry.
