Uniform Color Code
The American Public Works Association (APWA) developed a color code for temporarily marking underground facilities before excavation. The color code encourages all excavators, surveyors and engineers to use these colors to promote and eliminate damages to workers and the general public as well as prevent service interruptions to vital underground utilities.
Marking underground utilities with paint, flags, surface markers and underground marking tapes allows all excavators to understand the types of facilities and the approximate locations and routes of buried lines.
Types of utility markers that are flagged:
Temporary Survey Markings
Electric Power Lines, Cables Conduit, Lightning Cables
Gas, Oil, Steam
Communication, Alarm, Conduit
Reclaimed Water, Irrigation, Slurry Lines
Sewer and Drain Lines
