Engineering firm Mulligan Geotechnical has been appointed to carry out a $8.5 million maintenance works project on the Burdekin Falls Dam.
Water Supply Minister Mark Bailey said the work, which would support about 24 jobs, was part of SunWater’s ongoing program to maintain safe and efficient dams.
“The Burdekin Falls Dam Foundation Drainage Improvement Project will enhance the structural integrity of the dam by improving the efficiency of its water drainage systems,” he said.
“Mulligan Geotechnical was selected for its expertise in performing work on difficult access projects at large dams and will undertake complex geotechnical drilling work inside the dam gallery.
“The company has a large knowledge base and experience to manage the complexities that arise from these specialist projects.”
Minister Bailey said the contractor was committed to supporting the local community in Ravenswood and surrounding districts in the form of meals, fuel and miscellaneous supplies.
“The safety improvements will start next Thursday (April 20) and works are expected to be completed by the end of the year, weather permitting,” he said.
With a storage capacity of up to 1,860,000 ML – four times the capacity of Sydney Harbour – the Burdekin Falls Dam supports more than 1000 irrigation, industrial and urban water customers in the Burdekin Haughton water supply scheme.
Mulligan Geotechnical has previously completed similar successful large-scale dam projects including Hydro Tasmania’s Rowallan Dam spillway upgrade and Clark Dam foundation drainage upgrade, and the Somerset Dam upgrade for Seqwater
