Residents on Milford Road and Francis Street will be boiling their water over the Easter weekend.
Contractors putting in a new sewer main on Milford road accidentally broke a water main.
To fix it, crews from Saint John Water had to isolate a section leaving some residents without water.
The Department of Health is aware and the boil water order impacts the civic numbers 5 to 46 Milford Road along with 5, 20 and 22 Francis Street.
Water should be brought to a rolling boil for a full minute and then cooled before it can safely be consumed.
Two consecutive clean tests are needed before the boil water can be rescinded.
The boil water order is expected to last into early next week.
