Industrial use
Water is the lifeblood of industry. It is used as a raw material, a coolant, a solvent, a transport agent, and as a source of energy. An automobile coming off the assembly line, for example, will have used at least 120 000 litres of water 80 000 to produce its tonne of steel and 40 000 more for the actual fabrication process. Many thousands more litres of water are involved in the manufacture of its plastic, glass, fabric components. Manufacturing accounted for 15% of water withdrawals in 2005. Paper and allied products, primary metals, and chemicals were the three main industrial users.
