When the Tap Runs Dry
It was a quiet Tuesday night when the power went out. At first, it was just the lights. Then, the water pressure dropped to a trickle. Within hours, the entire neighborhood realized they had no access to clean water. Panic set in—not because there wasn’t enough food, but because no one had thought about storing water. Most of us assume clean water will always flow from our taps. But in a crisis, that assumption can dry up fast.
Whether it’s a natural disaster, a boil advisory, or a long-term emergency, knowing how much water to store and what kind to store can make all the difference. This guide breaks it down into clear, manageable steps so you can be prepared—not panicked.

The 3-Day Rule: How Much Potable Water Do You Really Need?
Potable water is water that is safe to drink and cook with. According to FEMA and the CDC, you should store at least one gallon per person per day for a minimum of three days. That’s:
– 3 gallons per person (minimum)
– Add additional gallons for pets, medical needs, and hot climates
Example for a family of four:
– 4 people × 1 gallon × 3 days = 12 gallons
– Add 1–2 gallons extra for cooking, hygiene, or pets
Longer-Term Planning: If you want to prepare for up to two weeks, aim for 14 gallons per person.
💡 Pro Tip: Use BPA-free containers or food-grade barrels with secure lids. Rotate stored water every six months to keep it fresh.

Non-Potable Water: What It Is and Why You Still Need It
Non-potable water isn’t safe to drink but is still essential. It can be used for:
– Flushing toilets
– Washing clothes
– Cleaning surfaces
– Bathing (with caution)
You don’t need to purify this water, but it should be free of chemicals and debris. Collecting rainwater in barrels or using greywater from sinks is a common method.
Storage Tips:
– Mark containers clearly as “non-potable”
– Keep separate from drinking water to avoid cross-contamination
– Store in cool, shaded areas to reduce bacteria growth
💡 Quick Tip: A standard toilet flush uses about 1.6 gallons. Store at least 1–2 gallons per person per day for sanitation needs in an emergency.

Purification and Treatment: When Stored Water Isn’t Enough
Emergencies don’t always follow schedules. If your stored water runs low, treatment becomes critical. Common methods include:
– Boiling: Kills most pathogens (1 minute at a rolling boil)
– Chlorine bleach: Use unscented bleach (8 drops per gallon)
– Water purification tablets: Lightweight and portable
– Filters: Use gravity-fed or pump-style filters for bacteria and protozoa
💡 Important: Never rely on a single purification method. Combine methods for added safety, especially with questionable water sources.

Storage Strategies: Space-Saving and Smart Solutions
Worried about where you’ll put all that water? Try these storage strategies:
– Under-bed containers: Store flat, stackable water bricks
– Closets or basements: Use 5-gallon stackable jugs
– Garage or shed: Consider 55-gallon drums with siphon pumps
– Car kits: Include small bottles or pouches in your emergency kits
💡 Calculation Reminder: For every extra person or pet, add one gallon per day.

Final Thoughts: Don’t Wait for the Crisis
Water is the most essential resource in any emergency. Unlike food, you can’t survive more than a few days without it. By storing both potable and non-potable water—and understanding how to treat and manage it—you’ll be prepared for unexpected situations.
Start with three days, scale up to two weeks, and you’ll have peace of mind knowing you won’t be caught off guard when the tap runs dry.
