What are the meanings of each of the multi-colored spray paint marks and tape used by the utility companies before digging up a street or surveying land?

Ken Little

Colors used by utilities are standardized, said Larry Brooks of Progress Energy.

According to Brooks:

• Red indicates electric power lines, cables, conduits and lighting cables.

• Yellow is for gas, oil, steam, petroleum or gaseous material.

• Orange indicates communication lines and cable TV, alarm or signal lines or conduits.

• Blue means potable water.

• Green is for sewer or drain lines.

• White denotes proposed excavation.

• Pink indicates temporary survey markings.

• Purple is for reclaimed water, irrigation or slurry lines.

“Call 811 before you dig,” Brooks said.
