If you need to report a water related problem during regular business hours, such as a leaking water meter, a water quality concern, a possible water main break or no water at the tap, please contact the Town office at 519-928-5652.

If you are calling after regular business hours, please contact 519-942-5695 to report the problem.

The Town conducts regular water system maintenance to maintain water quality and to ensure our infrastructure is repaired or replaced as needed.

Watermain Flushing

Watermain flushing is done in the spring and fall. Flushing cleans our iron and sediment that has gathered in the Town's watermains.

The flushing process may create discloloured water at the tap. Running the cold-water tap in your home for five minutes will usually clear the discoloured water. If that does not work, wait an hour and try again. We recommend that you wait until the water clarity returns to normal before drinking it.

Hydrant Maintenance

Hydrants are part of the Town's water infrastructure and are tested annually in the spring.

They help save lives in the event of a fire. Please help the Town keep hydrants visible and easy to access by not blocking any hydrant with plants, shrubs, fences, etc.

The Town is planning for anticipated growth in our urban area, which means we will need to provide safe and reliable drinking water to more residential, industrial and commercial customers in our urban centre.

We are reviewing various scenarios to estimate future water demand, and are developing alternatives for additional supplies to meet this future demand.
