Preparing Your Own Containers of Water
It is recommended you purchase food grade water storage containers from surplus or camping supplies stores to use for water storage.
Before filling with water, thoroughly clean the containers with dishwashing soap and water and rinse completely so there is no residual soap.
If you chose to use your own storage containers, choose two-liter plastic soft drink bottles – not plastic jugs or cardboard containers that have had milk or fruit juice in them. Milk protein and fruit sugars cannot be adequately removed from these containers and provide an environment for bacterial growth when water is stored in them. Cardboard containers also leak easily and are not designed for long-term storage of liquids. Also, do not use glass containers, because they can break and are heavy.
