Undergoung Utilities and their Standard Colors
It is now easier to know what an underground utility line is for. 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. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. 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. You dont want something disastrous to occur. If you hit any of the underground utility lines while digging then you can be fatally injured. 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.
Marking lines may lessen the risks but there are time when accidents still happen. The reality is that there is an incident almost every 6 minutes where utility line are struck. When this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. Public heath and safety is affected when this happens.
With the use of GPR or Ground Penetrating Radar, companies can locate utility lines. This has made it easier to locate utility lies underground and other important things. However, for the ordinary homeowner, it is enough to simply call 811 to be able to let companies located their lines.
It is easier to identify underground utility lines today because they now use different colors for each utility. Below are some of the colors used for different utility lines.
Proposed excavation sites use white lines. Area that will be excavated in the future are marked.
Pink lines are temporary survey markings. These are used by surveyors to mark off legal property boundaries.
Red lines are used to mark electric power lines, cable, conduit, and lighting cable. 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.
If you see orange lines, then you should associate this with communication., alarm, signal lines, cable or conduit. Blue lines are used for potable water. If you see purple lines, that this is for reclaimed water, irrigation and slurry lines. Sewer and drain lines use the color green. Hitting this line can truly derail any project for a long period of time.
