Web Page - Water Requirements for Industrial Uses

Quantities listed on this page are those of water intake (amount pumped into an establishment) rather than actual use. Thus the ranges listed reflect differences in the use of the water as well as the processes and products. Thus even though the amount of water used in the process may be the same from one factory to another, the amount pumped into the factory can vary widely depending on local factors.
