Shutting Off Your Water

Homeowners are responsible for the water lines from inside your house to the property line such as leaks and broken water pipes. You can repair issues inside your house by shutting the water off at the main shut-off valve. This is usually located in the basement.

If the inside shut-off valve is broken or you cannot turn it off call 905-546-2489 for an emergency shut-off at the curb. You will need to call back again to turn the water back on.

Shut-off valve at the curb

• usually located on the city sidewalk or at the property line
• approximately three inches in diameter
• stamped with either HWW (Hamilton Water Works) or WATER

Keep this valve visible at all times. If there is an emergency, this will help staff find it and turn off the water supply quickly.

Raise, lower, repair or locate your outside water shut-off valve

Call 905-546-2489 to schedule an operator to raise, lower or repair your outside shut-off valve.

To locate outside water lines, visit Ontario One Call or call1-800-400-2255. They will send a request to all of the utility companies that have underground services at your address to locate the services on your property.

Working Around the Shut-off Valve

Before starting any work, property owners that are looking to have their driveway installed or reconstructed should call Hamilton Water at 905-546-2489 to have the shut-off valve at their property line inspected and raised. If the shut-off valve requires repair, the combined process of obtaining underground utility locates and coordinating staff and equipment to complete the work typically takes between 6 to 8 weeks. For this reason it is important to make the request to check the shut-off valve as soon as possible before paving.
