How Much Water Do You Need for Emergency Storage?

How Much Water Do You Need for Emergency Storage?

FEMA recommends storing at least one gallon of water per person per day for drinking and sanitation. For a family of four for three days, that's12 gallons—weighing96 pounds and taking up significant space.

The Problem with Water Storage

Storing large quantities of water presents several challenges:

  • Space: Water takes up a lot of room
  • Weight: Water is heavy (8.34 lbs per gallon)
  • Shelf life: Stored water needs rotation every6 months
  • Cost: Bottled water adds up quickly

A Better Solution: Portable Water Filtration

Instead of storing hundreds of gallons of water, consider a portable water filter like the Blackout Water Survival Straw. Here's why:

Space Savings

One Blackout Water Survival Straw (2 oz) can replace2,000+ pounds of stored water over its1,800-gallon lifespan.

Unlimited Clean Water

As long as you have access to any freshwater source (creeks, lakes, puddles, even swimming pools), you have unlimited clean water.

No Rotation Needed

The Blackout Water Survival Straw has no expiry date. Store it in your emergency kit and it will work identically whether you need it in3 months or3 years.

Hybrid Approach

We recommend a hybrid approach:

  1. Store3-7 days of water for immediate needs
  2. Keep a Blackout Water Survival Straw for long-term water access
  3. Know where freshwater sources are located near your home

Water Sources in Your Area

During emergencies, these water sources may be available:

  • Creeks and streams
  • Lakes and ponds
  • Rainwater collection
  • Swimming pools (after filtration)
  • Water heaters (40-80 gallons of clean water)

The Smart Investment

For $29.95 (40% off), the Blackout Water Survival Straw provides peace of mind that no amount of bottled water can match. It's the smartest investment you can make for your family's emergency preparedness.
