The City of Cornwall maintains, inspects, and uses over 2,000 fire hydrants in our community.

Fire Hydrant Flushing

Hydrants are flushed once/twice a year. This is a Ministry of the Environment, Conservation, and Parks requirement to test…

  • Chlorine residuals,
  • Water quality, and
  • Adequate flow for firefighters.

When staff flush hydrants, nearby residents may see sediment in their water. Water may be brown or rust-coloured. Nearby homes may also experience reduced water pressure.

If you see that your water is discoloured, don’t drink the water or wash your laundry. Run the cold water taps in your home until the discolouration disappears. Discoloured water is not harmful to your health, but it can stain laundry.

If your laundry is stained due to discoloured water, call Municipal Works at 613-932-5354.

Snow Removal around Fire Hydrants

Adopt a hydrant near you!

After a major snow event, Municipal Works staff will do their best to clear snow from around fire hydrants. This process can take some time, especially if there are multiple major snow events in a short period of time.

You can help by adopting a hydrant! Clear snow from around your hydrant, and be sure to avoid piling snow from your driveway next to hydrants. If hydrants are buried in snow, this could seriously delay the Cornwall Fire Service’s ability to respond quickly to a fire. A little proactive work could save precious seconds in case of emergency!
