Burdekin Falls Dam Improvement Project

Burdekin Falls Dam Improvement Project

Burdekin Falls Dam, North Queensland

The Project will ensure the long-term viability of the dam by bringing its infrastructure into line with the safety requirements set out in the Water Supply (Safety and Reliability) Act 2008 (Qld).

The Project

The Burdekin Falls Dam Improvement Project will ensure the dam’s long-term viability by:

  • increasing its resilience to extreme weather events
  • bringing it in line with modern engineering design standards
  • ensuring it meets the safety requirements set out in the Water Supply (Safety and Reliability) Act 2008 (Qld).

Sunwater is preparing a detailed business case (DBC) to investigate options that will meet these objectives. The DBC also assessing the potential opportunity to raise the dam.

The project follows the Foundation Drainage Improvement Project, which was completed in 2017. This second, larger project will evaluate, determine and implement the most efficient scope of works to ensure the long-term viability of the dam. Specifically, it will focus on developing innovative techniques for the management of large catchment systems.

What’s involved?

The proposed works involves installing post-tensioned anchors across the spillway, adding additional concrete buttressing to the abutments, and raising the height and width of the saddle dams surrounding Lake Dalrymple.

Community Reference Group

A Community Reference Group (CRG) has been established for Burdekin Falls Dam as a forum for consultation and information exchange between Sunwater and community representatives about the Burdekin Falls Dam Improvement and proposed Raising projects.

Why Burdekin Falls Dam requires an upgrade

Dams are long-life assets and require continual assessment, monitoring and maintenance.

Burdekin Falls Dam continues to perform as it should however, assessments have highlighted actions Sunwater needs to take to bring the dam in line with modern engineering design standards and ensure the asset remains safe and productive for years to come. More information on how we assess our dams as part of our overall portfolio of dam upgrades is available here.

Burdekin Falls Dam is not a flood mitigation dam and no flood mitigation works are planned as part of the Dam Improvement Project or the Burdekin Falls Dam Raising Project.
