Digging around unmarked utilities can be dangerous and costly
If you do not have utilities marked and choose to work anyway – even for small projects like planting shrubs or installing fencing – you could risk personal injury or death, property damage and legal trouble. Coming into contact with an underground electric line it can shock or kill you and cause power outages, while contacting an underground gas pipe can lead to a fire or explosion.
Our representatives will mark utility lines within 48 hours of your call. For privately owned gas and electric utilities, you must have a qualified contractor mark the location, including pipes and wires that pass through MidAmerican Energy-owned meters.

Hand dig before using mechanized digging tools or excavators
The horizontal location of underground utilities will be marked, but their depth will not be. Any time you suspect unmarked hazards, hand dig the area carefully to test your suspicions. Backfill the soil gently to avoid damaging any utilities.
Excavator operators should take extra precautions. We recommend these four steps anytime anyone operates heavy digging machinery:
  • Look up: Ensure you are clearing overhead lines and trees.
  • Look down: Call or click 811 (call 811 or click, hand dig before you begin.
  • Look around: Always have someone outside the machine looking around blind spots.
  • Look often: Ensure that you are periodically checking your clearance.
