Building Queensland Role: Leading Detailed Business Case

Burdekin Falls Dam is located 210 kilometres south east of Townsville on the Burdekin River. The dam is owned and operated by SunWater and comprises a mass gravity main dam and three earth and rock-fill saddle dams. Since its construction in 1987, there have been changes to the dam safety standards and hydrological information. To reflect these changes, the dam needs improving to continue to meet current best practice standards.
The proposal is investigating improvement works to the Burdekin Falls Dam so the dam continues to meet current best practice safety standards. Proposed improvement works include:
- raising of saddle dams and spillway abutments
- installation of post-tensioned anchors to the dam’s main spillway and abutments
- installation of anchor bars at the downstream end of the spillway.
The works are expected to help prevent overtopping of the saddle dams and enhance stability in the monoliths to improve performance in extreme weather. SunWater regularly conducts dam improvement projects in line with national industry guidelines to maintain safe and efficient dam operation.
