Why must we always boil our drinking water during and after a cyclone has passed

Sometimes following a disaster, a boil water alert is issued for areas connected to mains scheme water because the mains water may be unsafe to drink or cook with.

If a boil water alert has been issued, it is essential you follow this warning to prevent illness.

To prepare water for drinking and food preparation, you should heat the water to a rolling boil for at least 1 minute using a stove or kettle and then allow it to cool. This will help to kill any bacteria.

Be sure to keep children clear from any boiling water until the water has cooled down to room temperature.

Once it has cooled it should be placed in the fridge in a clean container with a lid.

Under no circumstances should you drink or cook with water that has not been boiled until the alert is lifted.

Alternatively you can use bottled water.
