Step 1: Flush cold water tanks

If you have a cold water storage tank, or have been away from your property during the Boil Water Notice, you will need to run all your cold taps on full for 30 minutes to flush your system through. If you don’t have a water storage tank, your water is fed directly from the mains so as you have used the water for things like washing and toilet flushing, you will have been flushing your system already. We will automatically apply a run-off allowance to all our measured customers’ accounts for this.

Step 3: Make fresh ice cubes

You will need to discard all existing ice cubes, wash any containers that hold the ice, and remake.  If you have a plumbed-in ice machine you will need to discard the stored ice, create a fresh batch of ice (this will flush the plumbing), and repeat. The second batch of fresh ice will be safe to use.
