The Importance of Colors of Underground Utility Lines

Underground utilities can easily be identified today. The risk was high before when people could not easily identify the type of utility lines underneath whenever they dig. 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. If you need to dig through a piece of land today, you are required by the OSHA to first identify or locate underground utilities. Otherwise it can be something disastrous. If you hit any of the underground utility lines while digging then you can be fatally injured. Services in the area where the lines are located can experience interruption. People can call 811 to prevent these incidents, before they proceed with digging their property. Utility companies can then mark out their respective lines when you call them out.

Sometimes, even if the lines are marked accidents still happen. The reality is that there is an incident almost every 6 minutes where utility line are struck. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. Public heath and safety is affected when this happens.

GPR or Ground Penetrating Radar is used by companies to locate their utility lines. With this machine, companies can easily locate utility lines. Calling 811 is enough for the property owner to let companies located their lines.

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

If you see white lines, then these are proposed excavation sites. Area that will be excavated in the future are marked.

If you see pink lines, they are temporary survey markings. These are used by surveyors to mark off legal property boundaries.

Electric power lines, cable, conduit, and lighting cable use red lines. This color is appropriate for electrical works since it is associated with fire and danger.

Lines for gas, oil, steam, petroleum, and gaseous materials use the color yellow. The bright color yellow is used to be a warning sign since a natural gas leak can create a potentially disastrous situation.

Communication, alarm, signal lines, cable, or conduit use orange lines. Blue lines are used for potable water. Purple lines are used for reclaimed water, irrigation, and slurry lines. If you see the color green, then it indicates sewer and drain lines. You can derail any project for a long time if you hit these lines.
