Dr. Julia Gargano, an epidemiologist at the Centers for Disease Control and Prevention Waterborne Disease Prevention Branch, said: "Think about how much water you use every day. Now imagine if a water crisis were to happen and you didn't have safe water coming from your pipes."
All households should prepare for water emergencies by storing at least 1 gallon of water per day, for each person, Gargano advised.
"A two-week supply is ideal, but if that's not possible, we recommend that people store at least a three-day supply."
A proper disaster supply kit should include water, food and things like a first-aid kit, whistle to signal for help, and local maps.
