Beverage bottling begins by treating and filtering water to meet stringent quality control standards that exceed the quality of the local water supply. During the next stage of bottling process, the beverage moves to smaller holding tanks where additional various ingredients are mixed. The filling room is usually separate from the rest of the facility. This highly automated operation requires a minimal number of personnel.
Bottled water is filtered drinking water packaged in plastic or glass containers. The most popular form of retail packaging for water is the relatively new Polyethylene terephthalate bottle. Another type of packaging is larger high-density polyethylene plastic bottles, or polycarbonate plastic bottles often used with water coolers. Bottled water has reduced amounts of copper, lead and other metal contaminants since it does not run through the plumbing pipes where tap water is exposed to metal corrosion.
