Performance 2005-06 and trends
It is likely that there is some scientific information and data related to the impacts of AAD’s water extraction and use on ecosystems and habitats but this information is diffuse and not currently available in a consolidated form for reporting purposes.
Potable water at stations, AAD Headquarters, and Macquarie Wharf 4 is obtained from a variety of sources.
Macquarie Island: water is collected in Gadget Gully dam approx 250 m above sea level. It is gravity-fed 2 km to the station and then into the holding tanks.
Casey and Mawson: both these continental stations make use of a melt bell in frozen lakes near to the station. Heat from power generation and oil-fired boilers is used to melt the ice and pump it to storage tanks in warmed buildings.
Davis: Davis draws water from a frozen tarn near the station after melting it via oil-fired boilers. The tarn water passes to a reverse osmosis unit for desalination and is then pumped to tanks for storage.
Kingston and Macquarie Wharf: all water for AAD’s Tasmanian operations is purchased by Kingborough and Hobart city councils from Hobart Water.
