Undergoung Utilities and their Standard Colors

Underground utilities can easily be identified today. However, a long time ago, it was difficult to identify these utility lines and so when people try to dig there were many risks involved. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. 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. You dont want something disastrous to occur. 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. Before digging their property, people should call 811 to call the utility companies so that these incidents are prevented. 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. It is said that every 6 minutes, there is a utility line that is struck. When this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. This is then something that affects 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.

Pink lines are temporary survey markings. These are used by surveyors to mark off legal property boundaries.
