The pie charts compare the distribution of water consumption across five different sectors in Sydney, Australia, during two years: 1997 and 2007.
Overall, it is clear that the food industry accounted for the largest proportion of water usage in both years, despite experiencing a decrease. In contrast, water consumption increased in the service industry and manufacturing sector, while the building industry recorded the smallest share throughout the period.

Household use was the second-largest category at 19%, followed closely by the service industry (13%) and manufacturing (15%). The building industry accounted for the remaining 5% of total water consumption.

Manufacturing and household use saw slight shifts, rising to 11% and 21% respectively. Meanwhile, the share of water used in the building industry decreased to just 2%.
