Standard Utility Color Coding
We follow the American Public Works Association (APWA) Uniform Color Code for all utility markings:

White – Proposed Excavation

Pink – Temporary Survey Markings

Red – Electric Power Lines, Cables, Conduit, and Lighting Cables

Yellow – Gas, Oil, Steam, Petroleum, or Gaseous Materials

Orange – Communication, Alarm or Signal Lines, Cables, or Conduit

Blue – Potable Water

Purple – Reclaimed Water, Irrigation, and Slurry Lines

Green – Sewers and Drain Lines

What This Data Reveals

Water Infrastructure Dominance

Water utilities represent the largest category of underground infrastructure we encounter, highlighting the extensive municipal water distribution networks across our service areas.

Depth Accuracy Matters

With test holes averaging over 8 feet deep and reaching nearly 20 feet, precise depth mapping is critical for safe excavation planning and utility protection.

Complex Underground Networks

The variety of utilities – from traditional gas and electric to modern fiber optic networks – demonstrates the complexity of today’s underground infrastructure.

Growing Fiber Optic Presence

Our data shows significant fiber optic infrastructure, reflecting the ongoing broadband expansion initiatives across the United States.
