Keep Three Days of Water Per Person at Home

That's about 3 liters per person per day — just for drinking and basic hygiene. Store in clean, food-grade containers in a cool, dark place, and replace every 6 months. In an earthquake, flood, or infrastructure failure, clean water disappears within hours, and stores empty out just as fast. Having 9-10 liters per person already on your shelf means you don't have to panic, fight crowds, or boil river water. It's the most boring, most useful emergency prep you can do.
