Planet or Plastic | National Geographic Magazine: World’s Largest Bottled Water Plant

Bottles move down the conveyer belt at Poland Spring where between 345 and 425 employees working at the Hollis, Maine site oversee an array of computers and the water bottle production line. The 838,000 square-foot facility is the largest bottled water plant in the world, turning out about 80 million cases of water every year. Some of the machines fill 1,200 bottles per minute.
