Our readings indicated an average of about one leak for every two miles we drove within the study area.

Readings are from January 2015 through February 2016 and may not reflect current leaks, due to repairs or other changes.

If you ever smell gas, or have any reason to suspect a problem, experts say to immediately exit the building or area, then call the authorities. For more see the Atmos Energy safety page.

About Dallas' natural gas infrastructure

  • Utility: The Dallas area is serviced by Atmos Energy Mid-Tex Division. Most leaks don’t pose an immediate threat to safety or health, but some can. We have shared all data with Atmos Energy Mid-Tex Division, including any incidentally recorded leak points observed outside designated drive areas shown on the map.
  • Pipe materials: About 13% of mains operated by Atmos Energy Mid-Tex Division are made from cast iron or other leak-prone material.
  • Age of pipes: About 50% of the mains are more than 50 years old.
  • Progress: As part of a comprehensive pipe replacement program, Atmos Energy Mid-Tex Division is on schedule to eliminate all known cast iron in its system by 2021.
