Saint Andrews residents are being asked to boil their water.

An advisory was issued earlier today.

The water treatment plant on Harkness Road was taken offline overnight for a planned refurbishment.

It is now back online, but water should be brought to a rolling boil for at least 1 to 2 minutes before consuming it, or using it for brushing teeth or washing fruits and vegetables.

The boil water advisory is expected to last up to 72 hours.
