Locating a Line

Pipeline markers are used to identify the approximate location where a pipeline intersects with a street, highway, or railway.

These markers cannot be used to determine the exact position of a pipeline—you should always call 811 before you dig to avoid damaging pipelines and other underground infrastructure.

  • Pipeline Marker on a Natural Gas Pipe. There is a Delta Utilities logo at the top of the side of the pipe. On the left side is "CAUTION" in yellow letters with a black block background. "GAS PIPELINE" are on the right in black letters with a white background. Underneath those words, it reads, "LINE LOCATING TEST POINT". Underneath those words, it reads, "IN CASE OF EMERGENCY CALL 1-800-477-0177. Know what's below. Call before you dig."

  • Pipeline Markers

    Pipeline Markers contain operator information, product information, and an emergency contact number. These are the most commonly seen markers.

  • A yellow metal pipe with a curved top and a small rectangular sign is installed vertically in a grassy area near a road. The pipe appears weathered with some rust at the base, and it's surrounded by green grass and trees in the background.

  • Casing Vent Markers

    Casing Vent Markers indicate that a pipeline protected by a steel outer casing passes beneath a street, highway, railway, or other crossing.

This is a Delta Utilities graphic of a gas meter and pipes. The signs of a natural gas leak are hissing noises, an unusual odor of a rotten egg smell, abnormally dry or hard soil (shown in the graphic as cracked soil), discolored or dead grass or plants (shown in the graphic as brown grass by the natural gas meter and piping in the middle of green grass, or bubbling of liquid in wet or flooded areas (shown in the graphic as a puddle of liquid to the right of the natural gas meter and pipes).

Know What’s Below

The majority of natural gas distribution incidents are caused by damage to natural gas lines during construction and excavation activities. Whether you’re planting a new tree, installing a new fence, or completing a large-scale project, always contact the Call Before You Dig program by calling 811.

Homeowners and contractors are required by law to call 811 at least two working days before digging in Louisiana and at least three working days before digging in Mississippi.
