What do the paint markings and/or lines of little flags on the ground mean?

When someone calls the Ohio Utility Protection Service because they will be digging in the area, utility providers will come out and paint or flag their utilities to let the person who will be digging know where their utilities are located.

Different colors indicate the presence of various utilities:

Red:  Electric
Yellow: Gas
Orange: Communication (Internet/Phone/Cable)
Blue: Potable Water
Green: Sewers
