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.
