Protect yourself and your community.
Before every digging project, a call must be placed to 811.

If your company does excavation work, or if you are a homeowner or farmer who occasionally digs on your property, we need your help in preventing pipeline emergencies. Records show that damage from excavation-related activities, particularly from equipment digging into pipelines, is the number one cause of pipeline accidents. Without proper coordination, excavation activities in the vicinity of underground pipelines can result in very dangerous situations.

Before undertaking any work, excavators have a duty to call to locate any utilities buried beneath the work site.
In fact, it's the law.

The plan is simple…

  • Call your State's One Call System at least two working days before excavation is scheduled to begin (please check with your local One Call Center to verify how many days in advance you must notify the operator prior to excavation).
  • Wait the required amount of time.
  • One of our trained technicians will mark the location of the pipeline for you.
  • Respect the marks and carefully dig around the marked areas.
  • Dig with care.

what to do if you dig and disturb a pipeline

Even if you cause what seems to be only minor damage to the pipeline, you must notify the pipeline company immediately. A gouge, scrape, dent, or crease to the pipe or coating may cause a future problem. It is imperative that the pipeline owner inspect and repair any damage to the line or coating.
