Water Storage Basics

How much water to store, how to store it safely, and how to make water safe if supplies run out.

How much

Store at least one gallon per person per day, for at least three days — that covers drinking and basic sanitation. Two weeks is better if you have the space. Add extra for pets, hot climates, children, and anyone who is sick or nursing.

Store it right

Use food-grade containers or commercially bottled water.
Keep it cool and dark; away from gasoline, pesticides, and direct sun.
Replace stored tap water every 6 months; note the date.

Make water safe

If you run out, you can make most water safe to drink: bring it to a rolling boil for one minute, or add unscented household bleach (about 8 drops per gallon), stir, and let it stand 30 minutes. When in doubt, boil.

Scout your water sources before you need them. Walk your area now and note every reliable spring, creek, and standing pond within a mile of home—mark them on a paper map. In a crisis you want to know where water is, not go searching thirsty. Moving water and rain-fed sources beat stagnant, but treat all of it.

Stockpiling canned food does no good if you can't open it—keep two manual can openers with your stores, one in the kit and one in the kitchen. Test them on a can now; the cheap ones often skip or dull fast, and you don't want to discover that hungry in the dark.

Keep at least a week's worth of any prescription medications ahead of your regular refill, and store a printed list of names, doses, and prescribers with your kit. Pharmacies can be closed or out of stock for days after a disaster, and that written list speeds care if you end up somewhere new.

Test your fire kit before you need it, not during an emergency. Keep tinder in a waterproof tin and carry two ignition sources—a ferro rod works soaked, a lighter can fail cold or wet. In rain, gather dead branches still attached to standing trees; ground wood is nearly always too damp to catch.

Store a gallon of water per person per day and aim for a three-day supply at minimum. Refill sealed store-bought jugs every year, and keep a few in the freezer—they hold cold during outages and become drinking water as they thaw.

Start one skill this season: a small garden bed, a batch of canned tomatoes, a bag of beans cooked from scratch. Self-reliance compounds.
