The pie charts illustrate the consumption of water for five different purposes in Sydney, an Australian city between 1997 and 2007.
Overall, the charts highlight significant variations in water consumption throughout the period, where the food industry consumed the highest proportion in both years, while the building industry recorded the lowest percentage.
In 1997, the food industry remained the highest percentage of water use, at 48%, followed by the household use at 19%. This was comparatively higher than the proportion for manufacturing, at 15%. The service industry and the building industry, on the other hand, accounted for the lowest portions of water use, at only 13% and 5% respectively.
By 2007, the pattern had changed significantly. The figure for the food industry decreased to 41%, while household use increased to 21%. The service sector, however, showed a dramatic increase, reaching 25%. In contrast, the percentages for manufacturing and the building industry fell to 11% and 2% respectively, where the building industry remained the smallest category, at only 2%.
