Building a fence or a deck? Planting a tree?

If you are disturbing the ground anywhere on your property, you are required to locate underground services including City water and sewer services.

Before you disturb the ground for any reason, it is vital to your safety to contact Alberta One Call at 1-800-242-3447 or click the logo below to arrange a locate; AND contact Dig Shaw at 1-866-DIGSHAW (1-866-344-7429) to arrange locates.

Disturbing the ground can cause damage to buried utilities. Contact with a buried line can have results ranging from temporary loss of a service for property in the area to serious or even fatal injuries. The cost of damages caused to a buried utility are borne by the excavating party.  Whether you are a property owner doing landscaping, planting a garden, building a new fence, deck or other property improvements, a builder working on a site, or a contractor carrying out work that involves digging, it's vital to know where buried lines are present. Some lines are closer to the surface than you might expect.

Call Alberta One Call (1-800-242-3447) AND Dig Shaw (1-866-344-7429) to request line locates at least two full business days before you plan to work to allow time to have all the utilities at the property located and marked. You may request a locate up to 14 days in advance. Requesting your locates early during busy Spring and Fall seasons will help ensure the locates have been completed when you are ready to start your work.


Information for Your Safety

Like most utility owners, we have registered our lines with Alberta One Call. However, there may be buried lines on the property that Alberta One Call is not aware of.

Electric Light & Power, along with other utility owners and their locators are unable to mark:

  • Privately installed lines (e.g. power from your house to your garage, decorative landscaping, etc).
  • Secondary lines (e.g. electrical lines past the meter).
  • Customer-owned utilities (e.g. water and sewer lines are the responsibility of the property owner past the shut-off valve at the property line).

The utility companies do not own these lines and therefore do not have any information about their location.

You can find more information through Alberta One Call's Frequently Asked Questions.

You can also find more information through Dig Shaw's Resource Centre.
