Call Before You Dig

Even though underground pipelines are identified with pipeline markers, the main cause of pipeline leaks is damage caused by earth-moving and construction equipment and tools owned by parties other than the pipeline company.

  • If you plan to dig or do any type of excavation or construction work, call 811 from anywhere in the country a few days prior to digging, and your call will be routed to your local One Call Center.

  • Tell the operator where you're planning to dig, what type of work you will be doing, and your affected local utilities companies will be notified about your intent to dig.

  • In a few days, they'll send a locator to mark the approximate location of your underground lines, pipes, and cables, so you'll know what's below — and be able to dig safely.
