Water and food safety note

Water treatment, food storage, and preservation choices depend on source quality, storage conditions, allergies, health needs, and official local advisories. Verify labels, rotation dates, and public-health guidance.

Water

How Much Water Should I Store?

The basic rule is 1 gallon per person per day. But the real answer depends on your situation. Here's exactly how much water you need to store.

Quick Answer

Store at least 1 gallon per person per day for drinking alone. For total household needs (cooking, hygiene), plan for 3 gallons per person per day. A minimum 3-day supply is recommended, with 2 weeks ideal.
