In individual serving cans, it is less common alternative to bottled water. Canned water is often used where storage or distribution systems are set up for cans. Some companies have launched water in cans, claiming a more environmentally sustainable alternative to plastic bottles.
Cans of various sizes are also used for storage of potable water for emergency preparedness. Water is an important part of individual or government stockpiles. Water was stored in steel cans, lined with plastic bags, under the United States Civil Defense program. Approximately twelve million 17.5-US-gallon (66 L) cans were deployed, and could hold water for more than ten years.
Later, some manufacturers started to use Nitrogen flush to remove air and bacteria from their cans to prolong shelf life to 30 years or longer, making the water suitable for long term storage.
