The given bar chart compares the annual consumption of groundwater and public supply in seven industries in different nations.
As can be seen, almost all industries rely heavily on groundwater for production except for the food/drink and machinery industries. It is also striking to note that the chemical industry accounts for the largest amount of water usage, according to the survey given.
Regarding groundwater, the chemical industry is the dominant user with 430 million cubic meters each year, nearly doubling the water consumption of metals (240 million cubic meters). Meanwhile, paper ranks third at 190 million cubic meters, followed closely by food and drink, textiles, and fuel at 110, 80, and 70 million cubic meters respectively. Machinery, however, consumes the least amount of groundwater with only 10 million cubic meters, accounting for a tenth of that of public supply.
With regards to public supply, this water source is also dominated by the chemical industry, with 240 million cubic meters being consumed each year, followed by that amount used by food and drink (190 million cubic meters). Machinery and metal industries use less public supply for production, with 100 and 90 million cubic meters in turn. In contrast, fuel, paper, and textiles do not exploit much public supply for manufacturing items, ranging from 10 to 20 million cubic meters per year.
