Multi-purpose schemes - the Wivenhoe projectThe largest and best known multi-purpose water scheme in Australia is the Snowy Mountains Project, which combines power generation and water conservation for irrigation for use in several States. It is described in Chapter 6, as its principal technological features are concerned with the design and construction of dams, tunnels and associated engineering works.
The Wivenhoe Project in Southern Queensland is included in this section, as it is the largest and most advanced urban water supply-flood mitigation-pumped storage power generation project in Queensland and probably in Australia. This project, 90 km north-west of Brisbane, has three major elements -Wivenhoe Dam, Splityard Creek Dam and Wivenhoe Power Station.
Wivenhoe Dam is of the earth and rockfill type, with a full supply capacity of 1.15 million ML and an additional 1.45 million ML of flood storage. It will add 450,000 ML per annum to urban water supplies in the region and will have the effect of reducing a major flood event such as the 1974 Brisbane flood from 10,150 to 5,000 m3sec. This is equivalent to a reduction in flood height of some 2.5 m in the City business centre, which incurred millions of dollars worth of damage in that flood.
Good sites for pumped storage schemes are rare in Australia. Wivenhoe is one of these rare sites and its close proximity to Brisbane will produce very significant benefits for that city and the surrounding region.
