How deep are Enbridge’s pipelines buried?
At the time of construction, all of Enbridge’s pipelines are buried to a depth that meets, and in many cases, exceeds applicable legal regulations.
For example, the Canadian Standards Association's minimum depth of soil coverage requirement is 0.6 metres (24 inches), but we're proposing a minimum soil coverage depth of 0.9 metres (36 inches) for our new pipeline projects. Minimum depth of cover is established by the regulatory authority in the applicable jurisdiction; criteria often include safety, environmental impact, landowner impact and constructability.
Over time, wind and water may erode some of the surface cover of a pipeline. In those cases, Enbridge takes responsibility to address and remediate loss of cover. This may include adding fill or lowering the pipeline. We regularly monitor the depth of cover of our pipeline.
However, if you have concerns about changes to the depth of cover of a pipeline on your property, please let your local Enbridge representative know immediately.
