When a disaster hits, clean drinking water is the first thing people run out of. Hurricanes, floods, wildfires, or even a sudden boil-water advisory can shut down access in minutes. That is why emergency water storage is one of the most important steps for preparedness.
But the big question is: how much emergency water do you actually need — and how many cans should you store?
Emergency Water Storage Guidelines (Liters)
International recommendations (such as from the CDC and emergency agencies in Canada) suggest:
-
At least 4 liters per person per day → minimum for drinking and basic hygiene.
-
3 days minimum → 12 liters per person.
-
2 weeks preferred → 56 liters per person.
👉 For a family of 4, that equals 224 liters for two weeks.
How Many 355 mL Cans Is That?
Since Yes We Can Emergency Water comes in 355 mL cans, here’s the math:
-
1 person, 3 days (12 liters) = 34 cans
-
1 person, 14 days (56 liters) = 158 cans
-
Family of 4, 14 days (224 liters) = 632 cans
✔ Each 24-can case = 8.5 liters.
✔ Family of 4, 2 weeks = 27 cases of Yes We Can Emergency Water.
This puts preparedness into real numbers you can actually stock, stack, and store.
Why Canned Water is the Smarter Choice
Most households default to bottled water — but bottles degrade, leak chemicals over time, and require constant rotation. Canned water has clear advantages:
-
✅ Long shelf life — cans are hermetically sealed and lightproof.
-
✅ No rotation needed — unlike bottles, which typically expire within a year.
-
✅ Durable — cans withstand temperature changes better than thin plastics.
-
✅ Sustainable — aluminum is infinitely recyclable.
With Yes We Can Emergency Water, every can is factory-sealed for long-term storage, tested for purity, and always ready.
Smart Storage Tips (Canada & Cold Climates)
-
Store water in a cool, dark place (avoid direct sunlight).
-
Protect from freezing — water expands and can stress containers.
-
Keep some cases in portable locations for evacuation scenarios.
-
Always include extra liters for cooking and sanitation, not just drinking.

FAQs
Q: Can I rely only on purification tablets instead of storing water?
Not recommended. Tablets are a backup, but you still need a ready, reliable supply.

Q: How many cases should I store for my household?
For a family of 4, at least 27 cases for 2 weeks of full preparedness.
