A broken water main near the intersection of Sandy Point Road and Thornborough Street prompting the city issuing a boil water order.
Some homes will have either low water pressure or no water at all as repairs are carried out.
People who live on Sandy Point Road between Hawthorne Avenue and MacLaren Boulevard will have to boil their water before drinking it but not including Parkwood Avenue.
Also affected by the boil water order are the people who live along Thornborough Street, Jack Street, Kelly Lane, Anglin Drive including Anglin Crescent and Pidgeon Street, Kiwanis Court, Corkery Street and Cranston Avenue between Sixth Street and Thornborough.
The boil order is expected to be in effect until early next week.
The water is safe to use for showers, baths and to wash dishes without having to boiling it.
