What Size of Water Storage Drum Is Best for Families?

April 5, 2026

Quick Answer

A 55-gallon water storage drum is ideal for families of 2-4 people, providing enough water for approximately one week of drinking, cooking, and hygiene needs.

Choosing the Right Drum Size

When selecting a water storage drum for your family, consider the minimum water requirements for each person. The American Red Cross recommends at least one gallon of water per person per day for drinking, food preparation, and hygiene. For a family of 2-4 people, a 55-gallon drum is a good starting point, providing approximately one week’s worth of water. This size drum is also more manageable to store and transport than larger drums.

Drum Specifications and Materials

When shopping for a water storage drum, look for a drum made from food-grade polyethylene or polypropylene. These materials are durable, resistant to corrosion, and safe for storing drinking water. A 55-gallon drum typically measures 47 inches tall and 24 inches in diameter, making it easy to fit in most garages or storage areas. Consider a drum with a rust-resistant coating and a secure lid or closure system to prevent contamination.

Storage and Maintenance Tips

Proper storage and maintenance are crucial to keeping your water storage drum clean and safe. Store the drum in a shaded area, away from direct sunlight, which can cause water to degrade and potentially become a breeding ground for bacteria. Regularly inspect the drum for signs of damage or wear, and clean the drum with mild soap and water to prevent contamination.
