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. 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. 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. The worst thing that can happen if lines are not identified is that fatal injuries can happen. The location of the areas where the lines were struck can experience service 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. It is said that every 6 minutes, there is a utility line that is struck. When utility lines are stuck it causes disturbances in traffic lights wastewater pipes, telecommunication lines and more. Public heath and safety is affected when this happens.
Companies can locate utility lines through the use of GPR or Ground Penetrating Radar. This has made it easier to locate utility lies underground and other important things. 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. 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. Legal property boundaries are marked off by these pink lines.
Electric power lines, cable, conduit, and lighting cable use red lines. The color red is associated with fire and danger so it is just appropriate to use it for electrical works.
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.
Communication, alarm, signal lines, cable, or conduit use orange lines. If you see blue lines then these are lines for potable water. Purple lines are used for reclaimed water, irrigation, and slurry lines. Green lines are used for sewer and drain lines. Hitting this line can truly derail any project for a long period of time.
