How do I know where the pipeline is located?

In many areas it is easy to distinguish where pipelines are because of the cleared corridor known as the right-of-way where pipelines will be located. Since pipelines are buried underground, pipeline companies use line markers to indicate the approximate location of pipelines. The markers are placed where pipelines intersect streets, railroads, rivers and heavily congested areas. Markers indicate the general, not exact, location of a pipeline, but do not indicate how deep the pipeline is buried, or how many lines are in the area. Pipelines do not necessarily follow a straight course between two markers. Never rely solely on the presence or absence of pipeline markers. Always call 811 or your state’s One Call notification service before digging.
