The Importance of Colors of Underground Utility Lines
If you find underground utilities, you can easily determine what type of utility it is for. 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. It is thus important that we know how to identify these underground utilities if there is a need to dig the ground so that you can prevent harm. 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.
But, despite the marks, there will sill be accidents. 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.
Companies can locate utility lines through the use of GPR or Ground Penetrating Radar. When locating utility lines underground, this machine makes it easy to do so. Companies can locate their utility lines if any property owner calls 811.
There are certain colors that mark different utility lines for easy identification. The colors below indicate the kind of utility uses it.
If you see white lines, then these are proposed excavation sites. You can mark areas with white lines that will soon be excavated.
Pink lines are temporary survey markings. These are used by surveyors to mark off legal property boundaries.
If you see red lines, then you can be sure that these are electric power lines, cable, conduit, and lighting cables. The color red is associated with fire and danger so it is just appropriate to use it for electrical works.
Lines for gas, oil, steam, petroleum, and gaseous materials use the color yellow. Natural gas leaks can create potentially disastrous situations and this is why it is appropriate to use the bright yellow color.
Communication, alarm, signal lines, cable, or conduit use orange lines. Lines for potable water use blue lines. Purple lines are used for reclaimed water, irrigation, and slurry lines. If you see the color green, then it indicates sewer and drain lines. Hitting this line can truly derail any project for a long period of time.
