Plastic barrels for water storage

These little 15 gallon blue number 2 barrels used to hold Dr. Pepper syrup. After running bleach water and then baking soda and water threw them I will use them as water storage on olfarmranch until living full time on the homestead. I picked out the 15 gallons over the 55 gallons due to me being alone most of the time and it makes them easier to move. once they are all cleaned they are safe for storing drinking water.
