Full description
INDICATOR DEFINITIONThis indicator identifies the total amount of potable water consumed per person per day on each station. The figures are reported monthly to the Building Services Supervisor at Kingston.
TYPE OF INDICATOR
There are three types of indicators used in this report:
1.Describes the CONDITION of important elements of a system;
2.Show the extent of the major PRESSURES exerted on a system;
3.Determine RESPONSES to either condition or changes in the condition of a system.
This indicator is one of: PRESSURE
RATIONALE FOR INDICATOR SELECTION
This indicator gives the amount of water consumed per person per day at each station. It is also an indication of the volume of effluent and wastewater released, as all but an estimated 10% of water harvested is released. Water used on station is monitored closely, as it is a direct indicator of how efficiently each station is managing this resource. It is also related to the amount of energy consumed to produce water, as water production in Antarctica is a time consuming and costly process.
DESIGN AND STRATEGY FOR INDICATOR MONITORING PROGRAM
Spatial scale: Australian Antarctic continental stations and Macquarie Island station.
Frequency: Monthly reports
Measurement techniques: A conventional mechanical water meter is used to measure water consumption for Casey, Davis and Macquarie Island. A measurement of the volume of water in storage tanks each month provides Mawson's water consumption levels. In both cases the amount is then converted to a figure that represents water consumed per person per day.
At the Antarctic stations in the near future water consumption will be measured through the Building Monitoring and Control System (BMCS).

Statement: In looking at water consumption figures it is important to note that each station employs a unique method of water production and storage that may influence the interpretation of any figures obtained.
Davis Station: All of the water at Davis is drawn from a tarn and then processed through a continuous micro-filtration system and a reverse osmosis desalination plant. The water produced by these plants is pumped via a calcite filter to two 600,000 litre tanks for storage and then onto smaller tanks for consumption. Total water storage at Davis is 1,430,000 litres.
Mawson Station: Water at Mawson is produced primarily by melting snow and ice in a melt cavern using hot water pumped through a melt bell. The water is then pumped into storage tanks before passing through a gauze filter to the end user. During summer there is a limited amount of free water, this is water that runs off the plateau filling the melt caverns. Total water storage at Mawson is 270,000 litres.
Casey Station: Water at Casey is produced primarily by melting snow and ice in a melt cavern using hot water pumped through a melt bell. The water is then pumped into storage tanks before passing through a calcite filter to the end user. During summer there a limited amount of free water, this is water that runs off the plateau filling the melt caverns. Total water storage at Casey is 270,000 litres.
Macquarie Island: The water for Macquarie Island is run off from the plateau, water is collected in a small dam, piped to two storage tanks before passing through a gauze, sand and UV filters to the end user. The total water storage capacity at Macquarie Island is 104,000 litres.
