What Do All The Marker Colours Mean?

You’ve seen them out there, stakes lined up in a row, marching along the ditch or a field.  Or, sometimes, spray paint decorating the street or sidewalk, a variety of colours contrasting against the dull grey pavement.

What do they mean?  Why are they there?

When companies need to do maintenance to the road, sidewalk, power lines, pipelines or sewage lines, they need to have a Line Locating Technician to come out and locate, then mark, where all the potential buried lines are.

Once located and marked, companies Nation wide need to understand what they are, and thats where the standard underground utility colour code comes in.

Using universal colour codes ensures that everyone knows what is buried there, no matter the province, location, or client.
