The graph below shows the proportion of water used for different purposes in Sydney in 1997 and 2007 .
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The two pie charts give information about how the proportion of water used for five purposes changed in Sydney in 1997 and 2007. Over this span of ten years, the ratio of water used for household and services had both increased while for food, building and manufacturing had declined correspondingly.
To be more specific, only 8% of water was used for food, the smallest percentage in that year of 1997. Then, the figure ranked the last but one in 2007, with a sharp increase of 8%. Similarly, the share of water used in household also experienced a growth, occupying 16% in 1997 and 20% in 2007. Three of their counterparts, namely, food, building and manufacturing, saw an opposite trend. Manufacturing was the largest water-consuming sector in 1997, contributing to 33% of the total. A decade later, a slight drop of 3% could be seen in 2007 when the ratio still ranked at the top. The decrease in food was quite close to that in manufacturing, from 23% to 21% at the end of this period. In terms of building, there was a significant fall of 7% in water consumption.
Overall, water was mostly used in manufacturing and food in Sydney during these two years.
