Quick Answer
Old glass jars can be used for emergency water storage in urban apartments, but it's essential to choose jars that meet specific criteria and are properly prepared to prevent contamination.
Choosing the Right Glass Jars
When selecting old glass jars for water storage, look for ones that are made from non-leaching glass, such as soda-lime or borosilicate glass. Avoid jars with labels or coatings that may contain chemicals that can leach into the water. Opt for jars with tight-fitting lids to prevent contamination and evaporation. Some popular options include Mason jars, Ball jars, or Kerr jars.
Preparing the Glass Jars for Water Storage
Before storing water in the glass jars, ensure they are thoroughly cleaned and sanitized. Wash the jars with soap and warm water, and then rinse them thoroughly. Use a solution of one part unscented bleach to ten parts water to sanitize the jars, making sure to cover all surfaces. Let the solution sit on the surfaces for at least 30 minutes before rinsing the jars with clean water.
Storing and Labeling the Water
Once the glass jars are prepared and filled with water, store them in a cool, dark place to prevent bacterial growth and contamination. Label each jar with the date it was filled, the contents (water), and any other relevant information. Store the jars on a shelf or in a cabinet, making sure they are easily accessible in an emergency. It’s recommended to store at least one gallon of water per person per day, and to replace the water every 6-12 months to ensure its safety for consumption.
