How can I sanitize containers to store water for a disaster?

To sanitize containers for water storage in the event of a disaster:
  • Wash containers with dishwashing soap and rinse with water.
  • Sanitize by swishing a solution of one teaspoon of liquid household chlorine bleach to a quart of water on all interior surfaces of the container.
  • Rinse thoroughly with clean water before use.
Avoid re-using the following:
  • Containers that have ever held a toxic substance
  • Containers that can break, such as glass
  • Containers without a tight seal
  • Plastic milk bottles or cartons that can be difficult to clean and can break down over time.
Use of food-grade water storage containers, such as those found at surplus or camping supply stores, is recommended if you prepare stored water yourself.
