Decoding 811 Markings: A Guide to Understanding Utility Markings on Your Property
Have you ever noticed different colored markings, symbols, or flags along your sidewalks, driveways, or grassy areas, mysterious signs that read “811”? If you have, you might have been puzzled as to what these markings meant and why they’re present.
If you’re a property owner and plan on excavating or digging, it’s crucial to be familiar with the ‘811’ markings and what they signify. In this blog article, we’ll guide you through understanding the basics of 811 markings, why they’re important, what the colors signify, and what is underground.
What are 811 markings?
811 markings, also known as utility markings, are designations and symbols inscribed on the ground, signaling the presence of underground utilities or pipelines by various utility companies, including gas, water, sewage, or electricity.
These markings help prevent accidental damage to buried utility lines, which could lead to life-threatening injuries, environmental hazards, and costly repair bills. Therefore, it is essential to call 811, the one-call service, before embarking on any excavation work.
Why are 811 markings important?
811 markings are crucial since they guarantee that lines are adequately identified and protected. When digging takes place without taking the necessary precautions, there’s a high chance of hitting buried utility lines, which can lead to electrocution, carbon monoxide poisoning, explosions, and severe injuries, and sometimes even result in fatalities.
What do the colors of 811 markings signify?
Different colors of 811 markings signify different underground utilities. Here’s what they mean:
1. Red marks: indicate electrical power lines, cables, conduit, and lighting cable.
2. Yellow marks: signify gas, petroleum, and petrochemical lines.
3. Orange marks: denote underground communication lines, such as fiber optic and phone cables.
4. Blue marks: indicate potable water lines and associated connectors.
5. Green marks: signify sanitary sewers.

1. Electrical power and gas lines.
2. Communication and cable lines.
3. Water and sewage pipes.
4. Stormwater drains.

Conclusion
By now, you know the importance of 811 markings and what they indicate. Colors vary depending on the type of utility they represent, so be mindful of what they stand for. If you’re about to begin digging, make sure to call 811 or use the one-call system in your area, so the relevant utility companies can come and clearly mark the areas to be avoided. It’s always better to be safe than sorry. And remember, a little digging can lead to big changes, but only if done safely.
