How Much Water Should Be Stored for Home Emergencies in Winter? (Complete Guide)

Why Water Storage Matters in Winter Emergencies

In winter, water is one of the most overlooked parts of home emergency planning.

When temperatures drop, winter storms can lead to:

• • Frozen supply lines
  • Burst household pipes
  • Contaminated drinking water
  • Power outages affecting treatment plants
  • Road closures preventing resupply

That’s why every home needs a winter-ready water supply plan—not just for drinking, but also hygiene, cooking, and family health.

How Much Water Should You Store?

FEMA Recommendation

The U.S. Federal Emergency Management Agency recommends:

1 gallon (4 liters) per person per day

But in winter conditions, households should plan for 3–7 days of supply.

That means:

If you live in a remote area—or endure severe winters—storing a full week of water is recommended.

Why You Need MORE Water in Winter

People assume winter reduces water needs because the temperature is lower.

But in many emergencies, you may need additional water for:

✔ Rehydration in heated, dry rooms
✔ More hot drinks
✔ First aid cleaning
✔ Cooking shelf-stable emergency meals
✔ Pets that cannot go outdoors

Power outages also often eliminate access to hot water, meaning more water is needed for washing and basic sanitation.

Best Water Storage Options for Winter

1. Bottled Drinking Water

Advantages:

• • Ready to use
  • Safe, sealed, and long shelf life
  • Easy to rotate

Store in:

• • Temperatures above freezing
  • Dark, cool rooms (closets, pantry, basement)

2. Large Food-Grade Water Containers

Examples:

• • 5–20 liter barrels
  • Stackable emergency containers
  • Collapsible BPA-free tanks

These are ideal for:

• • Families
  • Rural homes
  • Multi-day outages

Be sure they are:

• • BPA-free
  • Labeled for potable water
  • Sealed to prevent contamination

3. Water Storage for Apartments

If you don’t have room for large barrels, alternatives include:

• • 3–5 liter stacking jugs
  • Collapsible 10-liter water bags
  • Under-counter storage tanks

4. Water Purification Backup

Because stored water can run out, your emergency kit should also contain:

• • Water purification tablets
  • Portable filters
  • Chlorine or iodine emergency kits

This lets you make questionable water safe if the crisis lasts longer than expected.

⚠️ Can Stored Water Freeze in Winter?

Yes—and it’s a common mistake.

Water expands when frozen, which can:

• • Crack storage containers
  • Destroy bottled water
  • Leave you without usable supply

Prevent Freezing By Storing Water:

• • Indoors
  • In heated areas
  • Away from outside walls
  • Inside insulated bins

If you only have a garage, store water:

• • Inside coolers
  • Inside thermal wrap
  • In sealed foam-lined containers

Additional Water for Hygiene & Sanitation

In a real emergency, water is needed for:

• • Handwashing
  • Cleaning minor injuries
  • Dental hygiene
  • Washing cookware
  • Pet bowls

Plan at least 0.5–1 gallon extra per person per day for these needs.

Don’t Forget Pets

Minimum:

1 ounce of water per pound of body weight per day

Examples:

• • • 20 lb dog = 20 ounces (600 ml)
    • 60 lb dog = ~60 ounces (1.8 liters)

Store extra—because stress makes both pets and humans drink more.

Put Water Storage Into Your Home Winter Emergency Kit

Water should be included alongside your other critical preparedness gear:

• • First aid supplies
  • Emergency thermal blankets
  • Portable lighting
  • Radios and power banks
  • Long-life food
  • Backup heating sources
  • Personal hygiene supplies

If your kit doesn’t already include water or purification supplies, now is the time to upgrade it.
