The next time you are out walking on the street, have a look at the sidewalk curbs. You will notice some cryptic markings either painted on the curb or carved into the curb like a Glyph or sometimes markings the on the shape of metal tags nailed into the concrete. Obviously, these markings were put there for some good reason, and so what do they mean?

Look at the curb outside your home or apartment and you will normally see letters carved into the concrete curbing. In residential housing the local municipalities and utilities like to have these marked to indicate where underground pipes enter the property from the street. The location and the type of service can be pin pointed by the marking on the curb. For instance, a common marking for a sewer line pipe is an “S”, and for a water line they usually use a “W” and for the gas line they mark a “G”. These are the obvious markings on residential curbs. When underground services are used for Cable TV a “C” is sometimes used, for buried phone cables a “P” is used and for Electric service an “E” is used. These services normally enter the property perpendicular to the curb so the mark is placed on the curb to mark the position of the service at that point.

Besides the permanent infrastructure marking there are also temporary markers that are usually spray painted onto the surface of the curb or sidewalk to notify construction workers that a pipe or cable is buried there and the color used indicates what the service is. Often the name of the service provider is also painted so the workers can contact them with any questions. The (APWA) American Public Works Association has developed a uniform color code for temporary marking of underground utilities.

The table below indicates the color and the service type associated with each color in the UNITED STATES.  CANADA has also adopted this color code except for the PINK temporary survey markings.

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
