Timeline: finalisation of preliminary business case expected in 2018

SunWater has determined an increase in the height of Burdekin Falls Dam is the best option for long-term water security in the Burdekin region once demand for water exceeds current capacity.

Following a Department of State Development study that forecast the potential short-term demand for water from Burdekin Falls Dam, SunWater is now developing a preliminary business case to further investigate long-term water supply requirements and options for raising the dam wall.

The viability of 2m, 6m and 14.6m raising heights is now being assessed. These rises in the height of the dam wall were allowed for in the original design of the dam.

Any raising of the dam wall would be a major construction project, requiring a significant capital investment. It is therefore vital to gather sound evidence of the demand for more water and the associated price to customers — both now and in the future — to support the investment.

Completion of the preliminary business case will position SunWater closer to construction readiness, should future demand for water necessitate raising the dam.

Dependant on the outcome of the preliminary business case, SunWater would then work with Building Queensland on a detailed business case under the Queensland Government’s Project Assurance Framework, and the preparation of an environmental impact statement. This process is likely to commence in 2019.
