Manufacturing - companies need water to manufacture their products e.g coca cola contains certain amount of water.

Plant cooling - Companies need water to cool their operating plants when they get heated up, coz over heating can cause damage to their machinaries.. e.g radiators in the card need water to cool ur car engines.

Constrcution - companies need water to construct new structure within their operating areas. e.g new building

Drinking - suprised? nope.. companies also provide drinking water in form of real water, coffee or tea to their staffs. thus, they need water for drinking.

Cleaning - companies also need water to clean their environment and maintain certain sanitary level. e.g water used to flush company'e toilets..

Many of de uses.. just think of what waters are used for in a company or ask daddy or mumy or aunt.. :)
