How Much Water Should You Store for an Emergency?

If the tap stops working, having your own water supply at home means one less thing to worry about. Here is what the U.S. government’s preparedness site, Ready.gov, recommends.

The basic rule: one gallon per person per day

Ready.gov recommends storing at least one gallon of water per person per day, for several days. That gallon covers both drinking and basic sanitation.

So a family of four planning for three days needs at least 12 gallons. For a week, at least 28.

Who needs more

• Children, nursing mothers and people who are sick may need more water.
• In very hot temperatures, water needs can double.

If you live somewhere hot, plan on the higher number.

How to store it

• Easiest option: buy commercially bottled water and keep it in its sealed original container, in a cool, dark place.
• Filling your own: use food-grade water storage containers and sanitize them first.
• Rotate it: water you bottle yourself should be replaced every six months.

One rule to remember

Ready.gov is clear on this: never ration drinking water unless authorities tell you to. Drink what you need today, and look for more for tomorrow.
