Utility markings
In the United States, the American Public Works Association (APWA) Uniform Color Codes for temporary marking of underground utilities are listed below:[13]
Red electric power lines, cables, conduit, and lighting cables
Orange telecommunication, alarm or signal lines, cables, or conduit
Yellow natural gas, oil, steam, petroleum, or other gaseous or flammable material
Green sewers and drain lines
Blue drinking water
Purple reclaimed water, irrigation, and slurry lines
Pink temporary survey markings, unknown/unidentified facilities
White proposed excavation limits or route
Some municipalities use the pink paint to make lines and codes on the pavements related to required street improvements such as ramp replacement, asphalt grinding and form injection. These markings are not related to utility locating
