Planning a home improvement project, planting a tree or installing a fence or deck?

With any digging on your property, here’s what you need to know first:

Excavation work, including digging or plowing around a home or business, is the most common cause of natural gas emergencies. Before digging around your property, state law requires you call 811, a nationwide, toll-free number, to have your utility lines professionally marked.

After calling, you must wait the required amount of time before digging. Your local utilities, like Virginia Natural Gas, will locate and mark, free of charge, and each with a different color paint or flag, where their underground utility lines are within the area where you want to dig.

Once that happens, you can dig with confidence, because you’ll know how to avoid any damage to these underground utility lines, which might interrupt or hinder your services and potentially damage your property.

Did you know that an underground utility line is damaged once every three minutes nationwide?

The good news is that nearly all these accidents can be prevented by calling 811 before digging. 

When you proactively call 811 before breaking ground, crews visit the site free of charge to mark the land where underground pipelines exist. That way, you know the spots to avoid and limit the need to call emergency repair crews, all while respecting your neighbors and the area around you.

Excavation work is the most common cause of natural gas emergencies. This includes something as small as digging or plowing around a home for an improvement project to breaking ground on a new building development. 

Safe digging makes safe communities. Do your part. Call 811 before you dig!

How 811 Works

  1. It takes less than two minutes. Call 811 at least three working days before you plan to dig. Provide your address, project type and approximate dig date. A dispatcher will determine whether or not you need to have your property checked for lines, and if so, schedule a marking window. Utility company representatives will be notified that your project site needs to be marked for safe digging.

  2. Within three working days, utility locator companies will arrive to spray or flag your yard, allowing you to avoid problem areas where lines are present. Markers will use a wand that detects line locations without any alteration to your property. You're not even required to be present while your project site is marked. If you end up getting busy and are unable to complete your digging before your marks fade, simply call 811 again and request a re-mark.

Respect the Marks

Once the lines are marked, use the appropriate digging methods and hand dig within 24 inches of the marked utility lines. This will help prevent any damage to underground utility lines.

Excavate Carefully

Make sure the marks remain visible during the entire project. If the marks are damaged or removed, customers are encouraged to call 811 to have lines re-marked. Excavation work, including hand digging with a spade or shovel or plowing around a home or business is the most common cause of natural gas emergencies. If a natural gas line is damaged accidentally or the distinct odor of natural gas is present, call 911 and the Virginia Natural Gas 24-hour emergency phone line at 877.572.3342 from a safe location. Do not operate any machinery or any equipment that might cause a spark.
