Maintenance work: Possible water discolouration

Category : Info-works
July 06, 2026

The City of Montreal will be carrying out maintenance work on the water network from July 7 to 9. This work may cause yellowish, brownish, or reddish discolouration of tap water throughout Montreal West.

This temporary disturbance may occur at various times during the work and is usually short-lived.

What to do if your water is discoloured

  • Turn on a cold-water tap, preferably the bathtub faucet or, if unavailable, the kitchen faucet. Commercial properties should use any available cold-water tap.
  • Let the cold water run until it becomes clear. The water can then be consumed safely.
  • If your faucet has an aerator, it is recommended to remove it before flushing the water.

Important: Make sure the water is completely clear before doing laundry or using any water-operated appliance to avoid staining fabrics or damaging equipment.

Thank you for your cooperation and understanding.
