Be a Dig Hero

Always call 811 before you start your project and dig safely once your project area has been marked.

Who Needs To Call 811?

Everyone whose project disturbs the ground (planting a garden, removing trees, installing sprinklers, adding a deck, and so many more) should call 811 at least 48 hours (excluding the day of notification, weekends, and holidays) before starting your project.

Anyone planning a project involving digging should always call 811 before they dig. This free service can prevent injuries and service disruptions.

To prevent injury, damage, and service outages, it’s crucial that underground utility lines be identified and marked before any digging project begins.

Whether you’re planting a tree, tilling soil, installing a deck or sprinkler system, or setting fence posts, always remember to call 811 at least 48 hours, excluding day of notification, weekends and holidays, before you dig to allow underground utility lines to be marked.

  2. Operator crews or subcontractors mark their underground utility lines with spray paint or flags. Or, they will let you know that they have no lines in the area.

It’s All About Your Safety

Avoid planting trees or large shrubs within three feet of your gas meter when planning outdoor projects. As the tree grows, it can exert forces on your meter setting which could result in damage to the natural gas pipeline.

You can help enforce safety laws, by shutting down any contractors you are using who do not use the OKIE 811 system.

The contractor or excavator that is performing the work is required to call 811 before starting their job. If your contractor starts digging before you see any paint or flags in your yard, ask them to stop until they’ve called 811.

By stopping the excavation work, you will avoid potential safety risks and protect your property by preventing damage to natural gas, electric, water and communication utilities.
