Answer 4

Paper factories area  good answer.  However, there are other factories which can waste much more water.  Manufacturing plants that use a tempering process wastes water.  Basically metal is heated to very high temperatures, then held a high temperatures (300 degrees) for a period of time.  To keep the solution from boiling, very high concentrations of salts are added.  When the process is complete, the metal part is dropped into a bath of running water to rapidly cool the metal and rinse of all the salt for the next steps in manufacturing.

Volumes: A parts manufacturer producing small metal pieces can use 3-5 gallons per minute per machine to wash and cool the parts.  A large scale manufacturer will then have 10-30 tempering machines operating 18-24 hours per day, 350-365 days per year.  This water is then typically discharged to the storm drain or sewer, depending on the juristiction and the salts used.  So, a range of "wasted water" is 11.3 to 78.9 MILLION gallons per year for one manufacturer.  This is the reason why many manufacturing plants have their own groundwater pumps.
