Seqwater appoints Aurecon and Entura to support Sideling Creek Dam upgrade

20 July, 2017

Queensland bulk water authority Seqwater has appointed global engineering and infrastructure advisory firm Aurecon and specialist power and water consulting firm Entura to support the Sideling Creek Dam upgrade.

Aurecon and Entura are partnering to deliver detailed design advisory for the upgrade of Sideling Creek Dam. The appointment follows a dam safety review and recent completion of complementary investigations and preliminary design of the upgrade work.

Sideling Creek Dam is located in the Moreton Bay regional area, about 30 km north of Brisbane. The 23 metre high zoned earthfill dam was commissioned in 1957 and upgraded in 1969. It consists of a 500 metre long embankment main dam and an 8 metre high, 70 metre long embankment saddle dam. 

“The Sideling Creek Dam upgrade is a critical part of Seqwater’s Dam Improvement Program,” said Colin Thompson, Seqwater’s Project Manager.

“The approved option for the upgrade involves strengthening the main dam and spillway and will allow the dam to be restored to its original full supply level once the upgrade is complete.”

“We’re delighted to be working with Seqwater on the Sideling Creek Dam upgrade to ensure it meets the Queensland dam safety guidelines into the future,” said Aurecon-Entura Project Director, David Thomas.

Entura brings a wealth of dam safety, design and construction support experience to the project. As part of Hydro Tasmania, Australia’s largest renewable energy producer and water manager, Entura draws on more than 100 years of experience of planning, building, managing and maintaining the many dams of Tasmania’s hydroelectric power system.

Aurecon brings outstanding geotechnical expertise as well as modelling and approvals experience. The two firms have been involved in other upgrade projects for Seqwater including Cooloolabin Dam upgrade and Moogerah Dam upgrade.

Entura has undertaken detailed design for many of Australia’s key new dam projects over the past decade, including Wyaralong Dam and Bromelton Off stream Storage in Queensland, the Samson Brook Pipehead Dam in Western Australia, the enlarged Cotter Dam in the ACT,  Suma Park Dam in New South Wales and the Meander Dam in Tasmania.
