How I Achieved Maximum Success with

Standard Colors for Your Underground Utilities

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. Although not completely eliminated, risks today have been reduced. In order to prevent harm, it is important to know or identify these utility lines if your need to dig the ground. The OSHA requires that utilities underground first be located before digging through a piece of land. Otherwise it can be something disastrous. If you hit any of the underground utility lines while digging then you can be fatally injured. It can also interrupt services in your area where the line is located. People can call 811 to prevent these incidents, before they proceed with digging their property. 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. These incidents affect public health and safety.

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

Today, utility lines are marked with different colors for easy identification. Here are the colors used for different utilities.

If you see white lines, then these are proposed excavation sites. You can mark areas with white lines that will soon be excavated.

If you see pink lines, they are temporary survey markings. Legal property boundaries are marked off by these pink lines.

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. Bright yellow is an appropriate warning color since it is very disastrous to have a natural gas leak.

Communication, alarm, signal lines, cable, or conduit use orange lines. If you see blue lines then these are lines for potable water. Reclaimed water, irrigation, and slurry lines used purple 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.
