The City of Laval is telling residents in the western third of the city to bring their tap water to a rolling boil for a minute before consuming.

The boil-water advisory has been in place since Tuesday. The city said it was due to a drop in pressure out of its control at the Chomedey filtration plant.

City officials are also asking people in the area affected to not fill their pools, water their lawns or turn the sprinklers on for the children while the boil-water advisory is in place.

The areas affected by the boil-water advisory are mostly west of Highway 15, and from the Mille-Îles River to Rivière des Prairies:

  • Chomedey
  • Laval West
  • Ste-Dorothée
  • Fabreville
  • Laval-Les Îles
  • Laval-sur-le-Lac
  • Part of Laval-des-Rapides to the east of Highway 15 and south of Highway 440

The city is also reminding people to toss ice cubes and other frozen items made after July 1 at 5 a.m. and to not wash fruits and vegetables intended for raw consumption with the water.

The city will continue testing the water over the course of the day.
