Total potable water consumption (litres)

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 INDICATORThere 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: PRESSURERATIONALE FOR INDICATOR SELECTIONThis 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 PROGRAMSpatial scale: Australian Antarctic continental stations and Macquarie Island station.Frequency: Monthly reportsMeasurement 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).Links to other indicatorsStation Fuel Usage, Sewage Outfall and Station Population
