The Importance of Colors of Underground Utility Lines

Underground utilities can easily be identified today. Before, it was difficult to do so and people were at risk if they try to make a dig without being able to identify all the lines underneath the land. Today, the risks have been lessened although not completely eliminated. In order to prevent harm, it is important to know or identify these utility lines if your need to dig the ground. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. Otherwise it can be something disastrous. Fatal injuries can happen if underground utility lines are struck. The location of the areas where the lines were struck can experience service interruption. To prevent these types of incidents, it is important for property owners to call 811 so utility companies can identify their undergoing lines. Calling the 811 number will enable utility companies to come out and mark their respective utility lines.

Marking lines may lessen the risks but there are time when accidents still happen. It is said that every 6 minutes, there is a utility line that is struck. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. Public heath and safety is affected when this happens.

With the use of GPR or Ground Penetrating Radar, companies can locate utility lines. This has made it easier to locate utility lies underground and other important things. However, for the ordinary homeowner, it is enough to simply call 811 to be able to let companies located their lines.

It is easier to identify underground utility lines today because they now use different colors for each utility. Here are the colors used for different utilities.

Proposed excavation sites use white lines. Area that will be excavated in the future are marked.

Pink lines are temporary survey markings. These are used by surveyors to mark off legal property boundaries.

Red lines are used to mark electric power lines, cable, conduit, and lighting cable. The color red is perfect for electric works because it is associated with fire and danger.

Yellow lines are used for gas, oil, steam, petroleum, and gaseous materials. Bright yellow is an appropriate warning color since it is very disastrous to have a natural gas leak.

Orange lines are used for communication, alarm, signal lines, cable or conduit. Blue lines are used for potable water. Purple lines are used for reclaimed water, irrigation, and slurry lines. Green lines are used for sewer and drain lines. You can derail any project for a long time if you hit these lines.
