During a boil water advisory, you need to boil your tap water before it’s safe to drink it, use it, or store it. Boiling kills harmful germs that might be in the water.
Follow these steps:
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 safe water in containers that are clean, disinfected (see below for how to disinfect containers), and made of food-grade plastic. Make sure they’re airtight and sturdy.
You can buy containers at department or camping supply stores, or use clean, disinfected 2-litre pop bottles with tight-fitting screw caps.
If you’re storing a lot of water (for example, in 10-litre or 18-litre water containers), make sure everyone in your home can lift the full containers. One litre of water weighs about 1 kilogram (2.2 pounds).

Follow these steps to clean and disinfect water storage containers:
Store water in a cool, dark place. Put the containers or bottles in dark, plastic bags to keep the light out.
You can store boiled water in well-sealed containers for 6 months. Write the fill date on the containers so you know when to refill them. Store at least a 3-day supply of 5 litres of water per day for each person or pet in your home—that’s 15 litres of stored water for each person or pet.
Store-bought bottled water is safe to keep for 1 year in the original, sealed container. Check the expiry date before you use bottled water.
