This table only applies the BBK reference value. Personal needs, pets and special circumstances may require additional water.
Several smaller containers may be easier
A 20-litre can reduces the number of containers but is heavy when full. Several 5- or 10-litre cans can be easier to carry and rotate.
Rotate rather than forget the stock
Emergency supplies should be checked regularly. With water containers, inspect cleanliness, odour, seals and the condition of the container.
Frequently asked questions
How much drinking water does the German BBK use for emergency planning?
The current BBK checklist uses 2 litres of drinking water per person per day and lets households plan for 3, 5, 7 or 10 days.
Does all emergency water have to be stored in canisters?
No. Packaged water and suitable water containers can be combined according to space, rotation and household needs.
Are 20-litre canisters always best?
No. A full 20-litre can is heavy; two smaller containers can be easier to carry and rotate.
