A quick container comparison
- 1.5 to 2 litre bottles
- Easy to lift and rotate, but create more separate bottles
- 5 litre bottles
- A useful middle ground if everyone who may need them can lift them safely
- 10 litre container
- About 10 kg of water before the container is counted
- 20 litre container
- About 20 kg of water, so it may be impractical to move when full
The simplest starting point
The UK Prepare campaign recommends purchasing and storing bottled water rather than filling your own containers with tap water. Commercial bottles are sealed in food-grade packaging and are the clearest starting point for a drinking-water reserve.
Check the label and follow the manufacturer's storage and best-before information. A practical rotation method is to use older bottles in normal household life and replace them during the usual food shop, so the reserve does not become a forgotten stockpile.
Split the total across containers that the people in your household can actually lift. One large container may use less shelf space, but several smaller bottles are easier to carry, share and replace if one is damaged.
Where reusable containers fit
A purpose-made, food-grade water container can be useful for temporary collection, transport or extra capacity. Choose one with a tight cover, a shape that can be cleaned properly, and a handle or tap that is practical at its full weight.
Follow the container manufacturer's cleaning and storage instructions. Do not use a container that previously held bleach, pesticides, fuel or other toxic chemicals. A container looking clean does not prove that it is suitable for drinking water.
For long-term drinking-water storage, do not assume a self-filled container is equivalent to an unopened commercial bottle. The UK guidance makes bottled water the preferred household option.
Build a manageable mix
- Calculate the target
Use the water calculator to find the household total before choosing containers.
- Test the lifting weight
Remember that one litre of water weighs about one kilogram before packaging. Choose sizes everyone who may need them can handle safely.
- Spread the supply
Avoid putting the entire reserve in one container or one place where a leak or access problem could affect all of it.
- Store it carefully
Keep containers away from direct sunlight, heat and household chemicals, and follow the manufacturer's storage instructions.
- Record and rotate
Keep the purchase or fill date and the label instructions visible. Rotate commercial bottles through normal use rather than inventing one replacement date for every container type.
Common mistakes to avoid
- Buying only very large containers without checking whether they can be lifted or poured safely.
- Reusing a container that previously held chemicals or an unknown substance.
- Leaving water in direct sunlight or beside fuels, pesticides or cleaning chemicals.
- Assuming a camping filter makes every contaminated water source safe.
- Forgetting water needed by pets, baby formula, medical equipment or a care plan.
During a supply interruption
Check advice from your water company and public authorities. A boil-water notice, do-not-drink notice and complete supply interruption require different actions. Do not use flood water or an uncertain source for drinking because it looks clear.
