Things to be aware of when storing water
How to store water
— up to the neck of a container with a sealable lid —
- Use a container that can be sealed cleanly (such as a plastic container, PET bottle or drinking flask) and fill it up to the neck to avoid contact with air as much as possible.
- When drinking stored water, to avoid contamination with bacteria, do not drink directly from the container, but pour it into a cup first and then drink from the cup.
- Some domestic water filters remove chlorine as well. So in the case of storing water, pour it directly from the tap into the container.
- If you boil it before storing, the chlorine from the water will be reduced. Please store the water exactly as it comes out of the tap.
Period for storing water
— 3 days at room temperature, around 10 days refrigerated —
- If stored in a cool location away from direct sunlight, water can be stored for around 3 days, or if refrigerated, for around 10 days, because the chlorine that has been added as a disinfectant will continue to be active for that period of time (It is a good idea to write the date on a memo and attach it to the container).
- You can drink the water after the storage period is exceeded if you boil it first.
Guidelines for volume to store
— 3 liters per person per day —
- The volume of drinking water needed for one day is said to be between 2 and 2.5 liters for an adult. Adding an extra margin of safety to that figure produces a storage target of 3 liters per day.
- Children younger than one year old only require 1 liter per child per day.
