Use durable food-grade water containers with tight lids. Never reuse chemical containers.
WATER · PRACTICAL PREPAREDNESS
Emergency water: how much, and how to store it.
Calculate a starting reserve, compare sizes, and set up a rotation you can maintain.
Your water starting point
6 gallons · about 23 liters
2 people × 3 days × 1 gallon. Add water for pets and individual needs.
Planning baseline: 1 US gallon per person per day, plus your entered extra. This includes drinking and basic uses, not a full household water budget. Add for pets, heat, illness, and food preparation as needed. It is not a limit on drinking.
Capacity is only half the decision.
A large container can simplify dispensing at home, but a filled seven-gallon container is heavy. Compare what you can lift, where it fits, and how you will get water out.
Choose a container you can handle.
| Water volume | Water weight alone, approx. | Practical tradeoff |
|---|---|---|
| 1 US gallon | 8.3 lb | Easier to lift; more individual containers. |
| 2.5 US gallons | 21 lb | A middle option if you can carry it comfortably. |
| 7 US gallons | 58 lb | Less frequent refilling; difficult to move when full. |
Weights exclude the container. Put the container where you will use it before filling. Keep an easy-to-carry supply available if you need to leave.
Fill, label, rotate.
Clean before filling
Wash and sanitize first. Follow the linked CDC container instructions; do not confuse container sanitizing with drinking-water treatment.
Label the reserve
Mark it as drinking water with the fill date. Replace home-filled water every six months; follow bottled-water dates.
Store thoughtfully
Choose a cool spot away from sunlight and chemicals. Keep the dispensing area clean.
