The water that drips from the lid into the cup is distilled. Summary Every home should have a supply of water stored for at least three days of emergency use. Store one gallon per person per day, and one quart per small pet. The water should be either municipal or bottled water, because these sources are inspected and tested regularly for many different contaminants. The container used for storing water must be clean, and made for food and water use.
Household bleach is the only disinfectant needed in the water for storage.
Rotate or use the stored water supply every six months.
