Description

Indicator Definition
This 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.

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).

Custodian evaluation

22 May 2002

The graph shows the typical seasonal variation of water consumption throughout the year. Total water consumption during the summer rises due the influx of summer personnel.

Ideally the graph should show ‘the per person per day consumption’ remaining constant and the total consumption rising with station population.

The water consumption figures for Mawson, Casey and Davis in summer 2002 show a marked improvement in water conservation compared with the previous summer.

The Macquarie Island graph shows a drop in the water consumption in July 2001, and again in February 2002. The drop in July 2001 was due to a frozen water line and the one in February 2002 was due to a dry summer and the presence of bacteria in the station water supply.

In 2010-11, total water consumption at stations was 6,705 kL, an average of 42.30 Kl per person per year. In 2011-12, total water consumption at stations was 7,011 kilolitres, an average of 48.02 kilolitres per person per year. Total potable water storage at Davis is 1 430 000 litres. It is drawn from the Davis tarn and processed through a continuous microfiltration system and a reverse osmosis desalination plant before pumping through a calcite filter to two 600 000 storage tanks and smaller tanks for consumption. Total water storage at both Casey and Mawson is 270 000 litres each. It is produced by melting snow and ice in a melt cavern using hot water pumped through a melt bell and then pumped into storage tanks. Total water storage at Macquarie Island is 104 000 litres. It is run off from the plateau, collected in a small dam and piped into two storage tanks before passing thorugh filters to the end user. LF
