The bar graph illustrates the average usage of 2 sources of water by seven industries in some countries every year.
Generally, groundwater is used virtually in most industries and the chemical industry consumes the most water of all the seven industries.
Firstly, the chemicals industry consumes around 430 million cubic meters per year, which is the greatest figure for water consumption. In addition, the usage of public supply in the chemical industry is also the highest with 240 million cubic meters every year. The lowest figure happens in fuel, paper, and textiles with 10, 20, and 10 million cubic meters of public supply used each year respectively. Groundwater is also much preferred in these countries with about 8 times more than that of public supply.
On the other hand, the amount of groundwater used in the metal industry comes in second place with 240 million cubic meters annually, just double the use of the same source of water in the food and drinks industry. However, the figure for public supply in the metal industry is just about half of that of the food and drinks industry with 90 and 190 million cubic meters comparatively. Lastly, machinery is the second industry that prefers public supply with 10 million cubic meters for the groundwater and 100 million cubic meters for public supply.
