The Essential Guide to Buying Emergency Water Storage

When disaster strikes, clean water becomes your most precious resource. Having a reliable emergency water storage system is crucial for survival. This guide helps you pick the best options for your family’s needs.

Key Features to Look For

Good water storage isn’t just about a big container. Look closely at these features:

  • Capacity: Experts recommend storing at least one gallon of water per person, per day. Think about how long you need to store water (three days minimum, two weeks recommended).
  • Durability and Leak Prevention: The container must resist punctures and cracks. Check for strong seals and robust construction.
  • Portability (If needed): If you might need to move your supply, look for smaller, stackable containers or water bricks. Large barrels are best for stationary storage.
  • Ease of Filling and Dispensing: A wide mouth makes filling easier. A sturdy spigot or tap ensures you can get water out without spilling.

Important Materials for Safe Storage

The material your container is made from directly affects water safety and storage time.

Food-Grade Plastics

Most reliable containers use high-density polyethylene (HDPE). This plastic is safe for long-term water storage. Look for the number ‘2’ inside the recycling triangle, which signifies HDPE. Never use containers that previously held chemicals or non-food items.

Stainless Steel

Stainless steel containers are extremely durable and do not leach chemicals. They cost more but last for decades. They are often used for smaller, high-quality survival kits.

Factors That Improve or Reduce Quality

Proper storage keeps your water safe to drink for years.

Improving Water Quality and Storage Life
  • Opaque or Dark Colors: Light encourages algae growth. Dark blue or black containers block light effectively, keeping water cleaner longer.
  • BPA-Free Certification: Ensure all plastics are certified BPA-free to prevent harmful chemicals from entering your drinking supply.
  • Airtight Seals: Excellent seals prevent evaporation and keep contaminants out.
Reducing Water Quality and Storage Life
  • Exposure to Sunlight: Storing barrels in direct sunlight drastically reduces water quality and can break down plastic faster.
  • Using Non-Food Grade Containers: Old detergent bottles or unknown plastics can leach toxins into the water.
  • Improper Cleaning: Containers must be thoroughly cleaned and sanitized before filling.

User Experience and Use Cases

How you plan to use your water impacts your purchase decision.

Home Base Storage

For most families, large 55-gallon water barrels are the best choice. These often sit in a garage or basement. They offer high capacity but require a way to siphon or pump the water out once it is full.

Go-Bag or Evacuation Kits

If you need water you can carry during an evacuation, focus on collapsible water pouches or sturdy 5-gallon stackable containers. These are lighter and easier to transport when empty, but they hold less overall.

Always store your water supply in a cool, dark place. Check and rotate your supply every six months to a year, depending on your container type, to ensure freshness.


10 Frequently Asked Questions (FAQ) About Emergency Water Storage

Q: How long can I safely store water in an emergency container?

A: If you use food-grade, opaque containers and store them in a cool, dark place, water can last for five years or more. Always check the manufacturer’s guidelines.

Q: Do I need to treat the water before storing it?

A: If you fill the container with clean, potable tap water, you may add a small amount of unscented, plain household bleach (check conversion charts for safety) to help preserve it. If you use commercially bottled water, no extra treatment is usually needed.

Q: Are water bricks better than round barrels?

A: Water bricks are often easier to handle and stack, saving space. Round barrels hold more volume overall but can be difficult to move once filled.

Q: Can I store water in standard plastic garbage cans?

A: No. Standard garbage cans are usually made from materials that are not food-safe and can leach harmful chemicals into your drinking water.

Q: What is the best way to get water out of a 55-gallon drum?

A: A manual siphon pump works well for safely transferring water from the bottom of the barrel to a smaller container.

Q: Should I store water outside?

A: Never store water outside where it can freeze or be exposed to direct sunlight. Freezing can crack the container, and sunlight degrades the plastic and promotes algae growth.

Q: How much water should a family of four store for three days?

A: Four people times one gallon per day times three days equals twelve gallons total. Aim for more, like two weeks’ worth.

Q: What does ‘BPA-Free’ mean?

A: BPA is a chemical sometimes used in plastics. ‘BPA-Free’ means the container does not use this chemical, making it safer for long-term food and water storage.

Q: What is the main benefit of opaque storage containers?

A: Opaque containers block light. Light allows algae and bacteria to grow in the water, making it unsafe to drink.

Q: How do I sanitize a water storage container before use?

A: Wash the container with soap and water. Rinse it well. Then, fill it with water and add a small amount of unscented bleach. Let it sit for 24 hours, then empty and rinse thoroughly before filling with potable water for storage.
