You Probably Have Enough Water for Tonight. What About Three Days?
By Marcus Ellery · July 31, 2026 · 6 min read

The standard guidance is one gallon per person per day, for three days. Half of that is drinking water. The other half is everything else: brushing teeth, washing hands, rinsing a plate, giving the dog something to drink.
| Household | Three-day supply | Roughly |
|---|---|---|
| 1 person | 3 gallons | Two 1.5-gallon jugs |
| 2 people + a cat | 7 gallons | A stack of jugs in a closet |
| Family of four | 12 gallons | One shelf, or two cases of bottles |
Where people actually put it
- Under the bed, in flat containers.
- The back of a hall closet, behind the vacuum.
- A bottom kitchen cabinet, replacing the appliance you never use.
- A collapsible container that lives flat and gets filled when a storm is forecast.

Worth knowing
