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. Although not completely eliminated, risks today have been reduced. If there is a need to dig the ground, it is very important that the utility lines first be identified. 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. 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. When the number is called, you can let the utility companies come out and mark their respective lines.
Sometimes, even if the lines are marked accidents still happen. Utility lines are struck every 6 minutes, some place. 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. When locating utility lines underground, this machine makes it easy to do so. However, for the ordinary homeowner, it is enough to simply call 811 to be able 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.
