Emergency Water Storage Buying Guide

Material and Safety

Always choose containers made from food-grade, BPA-free HDPE (high-density polyethylene). Avoid containers not labeled for water storage, as they may leach chemicals. UV stabilizers prevent plastic degradation if stored in sunlight. Look for DOT or FDA approval for peace of mind.

Capacity and Portability

Consider how you’ll use the water. Smaller containers (3-5 gallons) are easier to carry and stack. Larger containers (7-10 gallons) reduce the number of units but are heavy when full (over 60 lbs). For long-term storage, rotating water every 6-12 months is essential to prevent stagnation.

Seal and Dispensing

A tight, leak-proof seal is critical. Screw caps with gaskets are common, but some containers have built-in spigots. Check that spigots are made of brass or food-grade plastic and can be fully disassembled for cleaning. Avoid containers with narrow openings that are hard to sanitize.

Safety Notes

  • Only use containers specifically designed for water storage.
  • Wash containers with a bleach solution (1 teaspoon per quart of water) before first use.
  • Store water away from direct sunlight and heat sources.
  • Label containers with the fill date and replace water every 6 months.

What to Avoid

  • Avoid milk jugs or juice containers – they degrade and leak over time.
  • Avoid containers with plastic liners that can impart taste.
  • Avoid thin-walled collapsible jugs prone to puncture.
  • Avoid containers with metal parts that can rust.

FAQ

How long can I store water in these containers?

If stored in a cool, dark place, water can last 6-12 months. Replace every 6 months for best taste.

Can I stack these containers?

Only if the design explicitly supports stacking. WaterBricks are stackable; round containers are not.

How do I clean the container?

Use a mild bleach solution (1 tsp per quart) and shake vigorously. Rinse thoroughly. For stubborn residue, use a bottle brush.

Are these containers safe for drinking water?

Yes, if labeled BPA-free and food-grade HDPE. Avoid containers not marked for potable water.

Final Verdict

The WaterBrick Stackable Water Container is the best choice for most emergency prep, with Reliance Aqua-Tainer 7 Gallon as a close runner-up for value and Scepter 5 Gallon Water Can for budget-minded portability.
