Water is used in industries for cooling machinery and parts, as a solvent in many processes, as a lubricant in many more, and as a cutting tool under VERY high pressure. It is also used in cleaning processes, with or without soap and abrasives.
Older pipes, made of cast iron or lead, were often subject to clogging by mineral deposits (scales). Brass pipes tend to stay free of scale for longer periods. Today, low-pressure piping is often made of PVC and other rigid plastics. High-pressure piping is often made of rubber reinforced by an external steel mesh. And any piping used in the processing and preparation of food is, by law, made of stainless steel.

Water is used mostly for cooling in any industry - including pulp mills, chemical plants, refinary, power plants (coal fire/Nuclear/Geothermal).
It is also used as a transportation method, especially for Amazon's loggin companies.
D2O - heavy water is used as a part of the reaction.
Sewage water is used as the reinjection to the geothermal wells.
Some problems of water including the temperature pollution. The cooling water from any power plant usually have higher temperature. If discharged into the ocean, then it will raise the ocean temperature and harm the reefs.

Transportation. Getting product and raw materials from distributors and to market.
Cooling. CNC machines and plasma cutters all use water to keep the machinery from melting.
Ingredients to dillute concentrate.
