Damage Prevention

Did You Know?

It's the law to initiate a dig notice or One-Call ticket prior to digging or excavating. The greatest cause of pipeline damage is the failure to follow safe excavation practices. Calling 811, using soft digging practices near pipelines and maintaining contact with ONEOK is crucial to preventing possible injury or costly line strikes.

Effective and consistent use of the 811 system is critical to keeping our stakeholders safe.

811 is the national call-before-you-dig phone number. Anyone who plans to dig should call 811 or go to their state 811 center’s website a few business days before digging to request that the approximate location of buried utilities be marked with paint or flags so that you don’t unintentionally dig into an underground utility line.

811 protects you and your community! Hitting a buried line while digging can disrupt utility service, cost money to repair or cause serious injury or death. Always contact 811, wait the required time for utilities to respond to your request, and ensure that all utilities have responded to your request before putting a shovel in the ground.

*When planning to:

  • Excavate with equipment or shovel.
  • Trench.
  • Auger.
  • Tunnel
  • Grade an existing road or build a new road.
  • Install a culvert.
  • Cut or deepen a ditch line.
  • Dredge across a lake, river or bay.
  • Build a pond.
  • Install a drain tile.
  • Build a subdivision, new home, business or garage.
  • Install new utilities.
  • Install a swimming pool.
  • Build a deck.
  • Install a fence.
  • Plant trees or shrubs.

*This list is not inclusive of all digging examples and 811 should be called when disturbing the ground.
