The provided bar chart delineates the average annual residential water consumption across various Australian cities for the previous year, while the accompanying pie chart depicts the allocation of water consumption across different sectors in Australia for the same timeframe.
It is apparent that Perth exhibited the highest average water consumption, whereas Canberra reported the lowest figures. Additionally, a significant proportion of water was utilized for agricultural purposes, with mining representing the smallest sector.
In examining the bar chart, Perth emerged as the city with the highest water consumption, utilizing approximately 350 kilolitres annually. This was followed closely by Sydney, which recorded about 300 kilolitres. Brisbane’s consumption was around 200 kilolitres, placed it as the third highest, while Adelaide slightly trailed with just under 250 kilolitres. Melbourne and Canberra exhibited markedly lower figures, with Melbourne consuming about 150 kilolitres and Canberra marginally higher at approximately 250 kilolitres, reflecting a considerable disparity in water usage across these cities.
Turning to the pie chart, the distribution of water consumption reveals that agriculture was the predominant sector, accounting for an impressive 67% of total usage. In contrast, households constituted only 9% of water consumption. The sectors of water supply, sewage, drainage, electricity, and gas supply each comprised 7% of the overall consumption. Manufacturing accounted for a mere 4%, while mining represented the least significant share of just 2%, indicating a stark variance in water allocation among different industries.
