If possible, purchase bottled water and keep it sealed until ready to use. You can also store water in thoroughly washed plastic, glass, fiberglass or enamel-lined metal containers. Never use a container that has held toxic substances.

Plastic containers, such as soft drink bottles, are best. You can also purchase food-grade plastic buckets or drums. Seal water containers tightly, label them and store in a cool, dark place. Rotate water based on expiration dates on bottles or every six months
