If You Smell Gas


Recognize Signs of a Natural Gas Pipeline Leak
Leaks from a natural gas pipeline are extremely rare. Year after year the National Transportation Safety Board statistics support the industry’s safety record. However, it is important to know how to recognize the signs of a leak if one were to occur in your area.

Call Right Away if you Notice:


  • vegetation over or near the pipeline which appears to be dead or dying for no apparent reason;
  • water bubbling at a creek, pond, river or any wet area;
  • dirt being blown or appearing thrown into the air fire or explosion near or involving the pipeline;
  • exposed pipeline, which may have been caused by a natural disaster such as flood or earthquake

  • hissing , whistling or roaring sound.

  • The gas will have a slight “rotten egg” smell.

    Natural gas is usually colorless and odorless, but our pipelines contain odorized gas.

If you suspect a gas leak leave your home immediately and call Centennial Utilities. During the work week from 8 a.m. to 4:30 p.m. call 763-784-6751. After hours calls should be made to Central Communications at 763-427-1212 or 911 and ask for Centennial Utilities.

  • Do not go near the area and keep others away from the site.
  • Do not start equipment or motor vehicles in the area. If the equipment or vehicle is running, do not attempt to turn it off.
  • Do not operate anything that may ignite a gas leak, including cellular telephones, lighters, flashlights or two-way radios.
  • Do not attempt to shut off any valves or extinguish any fires.
  • Do not ring doorbells to alert others of the leak. Knock with your hand.
