Can I Store Well Water in a 55-Gallon Drum?

April 5, 2026

Quick Answer

A 55-gallon drum can be used to store well water, but it's crucial to ensure the drum is food-grade and properly sanitized to prevent contamination.

Choosing the Right Drum

To store well water, you’ll need a food-grade 55-gallon drum specifically designed for water storage. Look for drums made from high-density polyethylene (HDPE) or polypropylene (PP), which are less likely to leach chemicals into the water. Check the drum’s certification with the U.S. Food and Drug Administration (FDA) or the U.S. Department of Agriculture (USDA) for compliance with food-grade standards.

Sanitizing the Drum

Before storing well water, sanitize the drum with a 1:10 ratio of bleach to water solution. Fill the drum with the solution and let it sit for at least 30 minutes. Then, drain the solution and rinse the drum thoroughly with clean water. This process will help eliminate any potential contaminants.

Labeling and Maintenance

Label the drum with the date it was filled, the well’s water quality, and any specific handling instructions. Store the drum in a shaded area, away from direct sunlight and potential contaminants. Regularly inspect the drum for signs of leakage or contamination, and replace the water every 6-12 months to maintain its quality.
