The bar chart illustrates the annual water consumption, measured in millions of cubic meters, across seven distinct industrial sectors, comparing the usage of ground water against public supply.
Overall, it is evident that the chemical industry is the most significant water user, whereas the fuel and textile sectors consume the least. Furthermore, ground water serves as the predominant source for the majority of industries, with the notable exception of the food and drink sector.
Regarding the highest consumption, the chemical industry utilizes 430 million cubic meters of ground water and 240 million cubic meters from public supply. Metal production also relies heavily on ground water, with 240 million cubic meters compared to only 90 million from public sources. Similarly, the paper industry uses 190 million cubic meters of ground water, significantly outstripping its public supply usage of 20 million.
In contrast, the food and drink industry is unique in its reliance on public supply, consuming 190 million cubic meters, while using 110 million of ground water. Machinery production shows a preference for public supply at 100 million cubic meters, compared to 10 million of ground water. Finally, fuel and textiles show the lowest overall consumption, both utilizing only 10 million cubic meters from public supply.
