Data confidence level:
Australians are relatively conscious about water usage, and many households have employed measures to reduce their water consumption. This FACT indicates the total average water usage per household in gigalitres for each state between the years 2012 to 2013.
Total household water consumption is calculated by combining the amount of water distributed to households by water providers with the amount extracted through bores and other self-extraction facilities. 'Self-extracted ' water use is calculated by applying a coefficient, based on average number of kilolitres used per household connection, to the households known not to be served by water providers. The state with the highest total water use is New South Wales with 570 gigalitres. The state with the least is the Australian Capital Territory with 29 gigalitres.
