The graph demonstrates the amount of groundwater and water from public supply that different industries in some countries utilize in a year. Units are measured in millions of cubic meters.
Overall, for most sectors, groundwater is favored over public supply, except for foods/drinks and machinery. Additionally, the chemicals industry accounts for the largest share of water usage for both water sources.
In terms of the machinery industry, only 10 millions of cubic meters of groundwater is used, the lowest in all 7 sectors surveyed. In contrast, water from public supply adds up to 100 millions of cubic meters, 10 times the other source. Similarly, the foods/drinks industry also utilizes more groundwater than public supply, with 190 millions of cubic meters compared to 110 millions of cubic meters.
On the other hand, 430 millions of cubic meters of groundwater is used for the chemicals industry, surpassing all others. Meanwhile, public supply provides more than a half of groundwater, at 240 millions of cubic meters, which is also the number for the amount of groundwater utilized for the metal industry. Regarding this sector, 90 millions of cubic meters of water from public supply is used for industrial activities. The paper industry witnesses a substantial difference between these two sources of water, with 190 millions of cubic meters of groundwater compared to only 20 millions of public supply.
The textiles and fuel industries have similar annual water usage, with 10 millions of cubic meters of public supply. In terms of groundwater, the textiles industry uses 80 million cubic meters, whereas the number for the fuel industry is slightly lower, at 70 million.
