The pie charts compare the water usage of various sectors of the economy in Sydney, in two years – 1997 and 2007.

Manufacturing and the building industry also witnessed a decrease in the percentage of water used, falling to 11% and 2%, respectively, of total water usage in 2007.
By contrast, there was an increase in the proportion of total water use in the other two sectors. The water used by the service sector rose from 13% in 1997 to 25% of the total in 2007. Household use increased slightly to reach 21% of the total in 2007.
