Sunwater has proposed upgrades to the Burdekin Falls Dam, located 200 kilometres south of Townsville. The Burdekin Falls Dam Improvement and Raising Projects aim to expand the capacity of the dam, bring the facility up to modern standards, enhance reslience to extreme weather events and improve water security.
The Raising Project is a proposal to raise the existing dam by two to six metres, increasing the storage capacity by 590,000 megalitres to a total of 2,446,000 megalitres. Works would include raising of the spillway, abutments and saddle dams, as well as adjustments to the spillway apron and possible changes to the access road alignment.
The Dam Improvement Project aims to ensure compliance with current design standards. The scope of works includes anchoring the main dam spillway, raising and buttressing of the abutments, raising of the saddle dams and ancillary works.
Aug 2020: Queensland declares the dam raising as a coordinated project, and detailed business case development commenced.
2025: Expected commencement of construction.
Aug 2020: The Queensland Government declared the Burdekin Falls Dam Raising Project a Coordinated Project and announced that a detailed business case into both the Raising and Improvement Projects would be developed by Building Queensland and Sunwater. Sunwater also commenced the EIS process through the Queensland Coordinator-General.
Jun 2020: Sunwater submitted a preliminary Business Case to Building Queensland for the Dam Raising and Improvement Projects.
The dam, owned and operated by Sunwater, is the largest dam in Queensland with a capacity of 1,860,000 megalitres. Water from the Burdekin Falls Dam supplies over 90,000 hectares of agriculture, groundwater recharge and aquifer management, supplementary urban water to the Townsville Local Government Area and coal mines in the Bowen Basin via the Burdekin Moranbah Pipeline. The site comprises a mass gravity main dam and four earth and rock-fill saddle dams.
The Burdekin Falls Dam Improvement Project follows the Foundation Drainage Improvement Project, completed in 2017.
