A curb box is a 100 mm (4") diameter metal piece of apparatus located in your front yard, placed on or within inches of the property line. It is usually placed at grade to allow lawn mowers to pass over it, or in driveways, which you may safely drive over.
The curb box allows EnWin to shut off the water to your premise should the need arise (i.e. to facilitate plumbing repairs). For this reason, it must remain accessible and operable at all times.
If you are planning to install a new driveway or do landscaping around your property line, please contact Ontario One Call at 1-800-400-2255. Your curb box will be located for you, free of charge.
Please note that if a curb box has been buried in a finished driveway by the homeowner, any required exposure of the curb box and repair of the driveway will be at the expense of the homeowner.
