You need to boil tap water before it’s safe to drink, use, or store. To do this:
If the water tastes flat, leave space for air in the container and shake it well a few times. This will add air to the water, which will make it taste better.
Store boiled water in clean, disinfected, plastic, food-grade bottles or containers. Make sure they’re airtight, sturdy, and won’t break easily. You can buy containers at department or camping supply stores, or use clean, disinfected 2-litre plastic pop bottles with tight-fitting screw caps to store water.
If you’re storing a lot of water (e.g., in 10-litre or 18-litre water containers), make sure everyone in the home can lift the full containers. One litre of water weighs about 1 kg (2.2 lbs).
Don’t store water in:
Store at least a 3-day supply of
5 litres of water per day for each person or pet in the home. This would mean at least 15 litres of stored water for each person or pet. If you can, store a 2-week supply, which would be about 70 litres per person or pet.
Store water in a cool, dark place. Put the containers in dark, plastic bags to keep the light out.
You can store treated water in well-sealed containers for 6 months. Write the fill date on the containers so you know when to use them by.
Commercially-bottled water is safe to keep for 1 year if it’s in the original, sealed container. Use all the water in one bottle before you open another one. Check the expiry date before you use bottled water.
