Storing water in food-grade plastic barrels is a great way to ensure a clean and safe water supply, especially in emergency situations.

Here is a step-by-step guide on how to properly store water in a 55-gallon food-grade plastic barrel using bleach.

Please note that it's crucial to use food-grade barrels and unscented, regular household bleach (containing 5.25% to 6% sodium hypochlorite) for water storage.

Materials Needed:

1. 55-gallon food-grade plastic barrel

2. Unscented, regular household bleach (5.25% to 6% sodium hypochlorite)

3. Water source (preferably treated and filtered)

Instructions:

1. Clean the Barrel:

   • Thoroughly clean the barrel with mild detergent and rinse it several times with clean water to remove any residue.

2. Prepare the Bleach Solution:

   • In a clean container, mix 1 teaspoon of unscented bleach per gallon of water. For a 55-gallon barrel, you'll need approximately 1/4 cup (or 4 tablespoons) of bleach.

3. Add Bleach to the Barrel:

   • Pour the calculated amount of bleach into the clean 55-gallon barrel.

4. Fill the Barrel with Water:

   • Fill the barrel with clean, treated, and filtered water. Leave some space at the top to allow for expansion if the water freezes.

5. Mix the Solution:

   • Close the barrel securely and roll it back and forth or gently shake it to mix the bleach evenly with the water.

6. Label the Barrel:

   • Label the barrel with the date of filling and indicate that the water inside is treated with bleach.

7. Regularly Rotate the Water:

   • Water should be replaced every 6 to 12 months to ensure freshness. Label the barrel with the filling date and set a reminder to rotate the water accordingly.

8. Use Properly When Needed:

   • Before using the stored water, check its odor. If there's a faint smell of chlorine (bleach), it indicates that the water is still safe to use. If there's no smell, you might need to re-treat the water before use.

Important Tips:

• Do not use scented bleach or bleach with additives, as these can contaminate the water.

• Always use food-grade containers to store water to prevent harmful chemicals from leaching into the water.

• Store the barrel in a cool, dark place away from direct sunlight to prevent the growth of algae or bacteria.

• Regularly inspect the barrel for signs of damage or leaks to ensure the water remains uncontaminated.

• In case of doubt about the water’s safety, consider using water purification tablets or other water treatment methods before consumption.

By following these guidelines, you can safely store water in a 55-gallon food-grade plastic barrel using bleach, ensuring a clean and potable water supply for your needs.
