VA 811 – Dig with CARE

Utility operators maintain the underground pipes and wires that serve your home. Part of their maintenance program is to mark their lines whenever someone places a “notice” or “ticket” with the Virginia 811 center.


Utility operators mark any underground line that is directly in the way of construction, or even near it. If your lawn is marked and you didn’t know about it, then either your neighbors are planning some work, a utility operator is planning maintenance or repair, or the Virginia Department of Transportation, or your Town, City, or County is planning excavation work.

Utility color codes are used to identify existing underground utilities in construction areas with the intent of protecting them from damage during excavation. This is done with either flags or a special spray paint, neither of which will cause long-term harm to your lawn.

The American Public Works Association (APWA) Uniform Color Codes for temporary marking of underground utilities are listed below:

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 potable (drinkable) water
Purple reclaimed water, irrigation, and slurry lines
White proposed excavation limits or route
