The Awoonga Callide Water Supply Scheme is located between Awoonga Dam 25 km south of Gladstone and Callide Dam 11 km east of Biloela.
The primary purpose of the scheme is to supply water for the Callide-B and Callide-C Power Stations.
The scheme was constructed in three stages:
1. The first stage, the construction of the Awoonga Callide Pipeline to supply water to Callide-B2, was completed in 1988
2. The second stage – the duplication of selected sections of the Awoonga Callide Pipeline to increase the pipeline’s capacity to extend the supply to Callide-C3, was completed in 2000; and
3. The third stage, the construction of the Stag Creek Pipeline to reduce transmission losses, was completed in 2005.
Uses of Water
Water is supplied to CS Energy Pty Ltd and Callide Power Management.
The Awoonga Callide Water Supply Scheme pumps water from Awoonga Dam to the top of the dividing range from where it gravitates into Callide Dam via the Stag Creek Pipeline.
Awoonga Callide Pipeline System
The Awoonga Callide Pipeline is approximately 54 km long and rises 528 metres. Three pump stations subdivide the Awoonga Callide into distinct sections; Awoonga-Wooderson, Wooderson-Bocoolima and Bocoolima-Stag Creek outfall at the top of the Calliope Range.
Stag Creek Pipeline
The Stag Creek Pipeline is approximately 14.9 km long. It is designed to carry the output of the Awoonga Callide Pipeline and was completed in 2005.
