Quick Answer
Yes, you can reuse old 55-gallon drums for water storage, but they must be thoroughly cleaned, sanitized, and inspected for structural integrity and potential chemical contamination.
Precautions and Preparation
When reusing old 55-gallon drums for water storage, it’s crucial to inspect the drums for any signs of damage, rust, or corrosion. Look for any openings, cracks, or dents that could compromise the integrity of the container. Use a hydrostatic test, such as filling the drum with water and checking for leaks, to ensure the drum is watertight. Also, be aware of potential chemical contamination from previous uses, such as pesticides, fertilizers, or fuels.
Cleaning and Sanitizing
To prepare the drum for water storage, clean it thoroughly with a mixture of bleach and water. Use a 1:10 ratio of bleach to water and soak the drum for at least 30 minutes. Then, scrub the interior surfaces with a non-abrasive brush and rinse the drum with fresh water. Finally, sanitize the drum with a 1:100 ratio of bleach to water and allow it to air dry.
Additional Considerations
For long-term water storage, consider adding a water treatment system or using a drum specifically designed for water storage. You may also want to consider using a drum with a screw-on lid or a tight-fitting plug to prevent contamination and spills. Additionally, be aware of local regulations regarding water storage containers, as some areas may have specific requirements or restrictions.
