PROJECT UPDATE: Callide Dam Radial Gates Upgrade


Onsite Rental Group were recently engaged to provide specialist rental equipment as part of the Callide Dam Radial Gates Upgrade program.

The equipment we provided included:
– Two 80ft Knuckle Booms;
– a 5t Excavator;
– an 6m x 3m Lunch Room package, and
– an 8KVA Generator.

Our equipment was used to install and connect electrical services as part of the Radial Gate upgrade works. The Excavator was required to dig the trench from the main electrical connection over to the spillway. Then our Booms were used to run the cables up and under the access bridge to finalise the electrical connection.

The Radial Gates are fitted in the spillway and are designed to open automatically using a float system when the storage reaches above the full supply level (FSL). The gates begin to open by being pulled up by the raising water level and continue to open as the storage continues to rise. Once the water levels recede, the gates lower. The gates operate this way to protect the integrity of the dam structure from water rising above the FSL. The gates minimise the risk of ‘overtopping’ the dam.

About the Callide Dam
The Callide Dam is an earth fill dam with radial gates which was constructed in 1965 and is located 12 kms from Biloela, QLD (approximately 90 kilometres south-west of Gladstone via the Dawson Highway). The dam supplies water for a nearby power station in Biloela and holds 136,300 megalitres at an average depth of 10.5ms with a surface area of 3,100 acres at full capacity.
