Canned water

Some companies have launched water in cans, offering a more environmentally sustainable alternative to plastic bottles.

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.

[2] Later, some manufacturers started to use a 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.

[5] Due to the detrimental impact of plastic on the environment, many manufacturers are turning towards aluminium cans and glass bottles as a more sustainable solution to packaged drinking water.
