Know Before You Dig: Understanding Utility Flag Colors in Campbellsville

Infographic from the City of Campbellsville explaining utility flag colors, including red for electric, orange for communications, yellow for gas, blue for water, green for sewer, purple for irrigation, white for excavation, and pink for survey, with safety instructions to call 811 before digging and not remove flags.

Before You Start Digging…

Planning a fence, garden, or outdoor project? Before you break ground, there’s one important step that can save you time, money, and serious trouble:

Know what’s below the surface.

Across Campbellsville, utility crews use color-coded flags to mark underground lines. These markers are there for your safety—and understanding them can help prevent damage and keep your project running smoothly.

What Do Utility Flag Colors Mean?

When you see small flags placed in your yard or along the roadside, each color tells a different story about what’s buried below:

  • Red: Electric lines
  • Orange: Communication lines (internet, cable, phone)
  • Yellow: Gas, oil, or petroleum lines
  • Blue: Potable (drinking) water
  • Purple: Reclaimed water or irrigation
  • Green: Sewer lines
  • White: Proposed excavation area
  • Pink: Temporary survey markings

These flags are placed after a locate request and help guide both homeowners and contractors during excavation.

Why You Should Never Remove Utility Flags

We understand—they can be a bit of an eyesore. But those flags serve a critical purpose.

Utility flags should never be removed by homeowners.

Removing or disturbing them can:

  • Lead to costly damage
  • Create dangerous situations
  • Result in fines or penalties

Only the utility company should remove flags once work is complete.
