Are Plastic Barrels Suitable for Storing Drinking Water?

Access to clean and safe drinking water is essential for households, businesses, agriculture, and emergency preparedness. Many people and organizations rely on large containers—such as plastic barrels—to store water for daily use or in case of shortages. But are plastic barrels actually safe for drinking water?

The answer is: yes — but only if you choose the right type of container and use it properly.

Below, we explain what makes a plastic barrel suitable for potable water storage — and we also present IBC totes and plastic pails as practical alternatives.

1. The Material Matters: Food-Grade HDPE Is Key

To safely store drinking water, the plastic barrel must be made from food-grade HDPE (High-Density Polyethylene).

Food-grade HDPE is:

• Non-toxic
• Chemically stable
• Durable
• Resistant to contamination
• Commonly used in food and beverage industries

Containers that are NOT food-grade should never be used for drinking water, even if they appear clean.

Rule of thumb: If it is not labeled food-grade or potable-water safe, do not use it for drinking water.

2. Look for Proper Certifications

A safe drinking water container should have clear certification, such as:

• FDA-approved (for food contact)
• NSF-certified for potable water storage
• Clear labeling stating “safe for drinking water”

If a supplier cannot confirm certification, it is safer to avoid the product.

3. New vs. Used Containers

Best option: Brand-new food-grade containers

These are the safest choice because they have never held other substances.

Used containers: only if verified

Reused containers can sometimes be safe — but only if:

• You know exactly what was stored before
• The container is food-grade
• It has been professionally cleaned

Never use barrels, totes, or pails that previously stored chemicals, oils, solvents, detergents, or industrial liquids.

4. Other Options for Drinking Water Storage

Besides plastic barrels, there are two excellent alternatives depending on your needs:

Option A — IBC Totes (for large volumes)

If you need to store a lot of water, food-grade IBC totes (Intermediate Bulk Containers) are a strong choice.

Typical capacity: ~275 gallons / 1,000 liters

Benefits:

• Very large storage capacity
• Built-in valve for easy dispensing
• Steel cage for protection
• Easy to move with a forklift or pallet jack
• Good for long-term or outdoor storage

Use cases:

• Farms and rural properties
• Emergency preparedness
• Community or shared water storage
• Construction sites needing clean water

What to check before buying:

• Food-grade inner liner
• Label confirming potable-water safety
• No history of hazardous chemicals
• Preferably new, or professionally reconditioned for food use

Option B — Plastic Pails (for small to medium storage)

If you don’t need hundreds of gallons, food-grade plastic pails are a practical alternative.

Common sizes range from 5 to 20 gallons.

Benefits:

• Easy to handle and transport
• Affordable
• Space-efficient
• Great for household use or short-term storage

Good for:

• Drinking water at home
• Camping or outdoor trips
• Emergency kits
• Small-scale water storage

Again, make sure the pails are clearly labeled food-grade and safe for drinking water.

5. How to Store Drinking Water Properly

Whether you use a plastic barrel, IBC tote, or plastic pail, follow these best practices:

• Clean and sanitize before first use
• Store in a cool, dark place (sunlight degrades plastic)
• Keep tightly sealed to avoid contamination
• Use a food-grade tap or valve
• Replace water periodically if used for emergencies
• Keep containers elevated off the ground

Final Verdict

Yes — plastic barrels can be suitable for drinking water, but only if they are food-grade, certified, and stored correctly.

If you need more capacity, a food-grade IBC tote is an excellent option.

 If you need smaller, portable storage, food-grade plastic pails work very well.

Choosing the right container depends on how much water you need, how long you plan to store it, and how easily you need to move it.
