Short answer: store at least one gallon of water per person per day for several days, in clean food-grade containers, away from heat and sunlight. Know how to disinfect more. The one-minute video from The Provident Prepper above sums it up: a clean container filled with clean water is all you need.
How much water?
Ready.gov advises at least one gallon per person per day for drinking and sanitation, for several days. Add more for hot weather, children, nursing mothers, the sick, and pets. A family of four needs at least 12 gallons for three days; two weeks is a better target.
What to store it in
- Sealed bottled water is the simplest option. Keep it in its original packaging.
- Food-grade containers if filling your own. Avoid containers that held milk or juice, which are hard to clean fully.
- Large barrels for long-term supply, stored off concrete and out of the sun.
How to treat water
The CDC's method for clear water: add 8 drops of unscented 6% household bleach per gallon (6 drops if the bleach is 8.25%), stir, and wait 30 minutes. Use only plain bleach with no scents or additives. If water is cloudy, filter it first. Boiling for one minute also works when you have fuel.
Rotate
Ready.gov suggests replacing self-filled stored water every six months. Watch expiry dates on bottled water, and keep it away from chemicals and fuels.

Documented vs opinion
Documented: quantities and rotation from Ready.gov; disinfection from the CDC. Opinion: water is the cheapest, most overlooked prep. Fill it before hurricane season, not during the warning.
