Disruption to water supply means water must be boiled until water is tested and declared safe.

Power and Water has fixed the problem, but the water still needs to be tested and declared safe to drink.

The Department of Health has issued an alert for residents to boil their water before drinking it, using it for food preparation or cleaning teeth.

It could be several days before testing is completed and it’s known whether the water is safe to use.
