4. It's Free & Easy
Contacting 811 and the utility marking service is free and available to everyone. It's as easy as dialing 811 or submitting a request online. In some areas, an app, may also be available to quickly submit a request from your phone or tablet.
If you are working with a contractor for your project, make sure you understand whose responsibility it is to make the request to have the utility lines marked. The service is free no matter who makes the request.
Once a request is submitted, crews in your area will mark your project area with color-coded lines, indicating the locations of underground utilities. Private utility lines are not marked by 811. Those include electric lines running from your home to a detached garage or shed, invisible pet fences, lines for satellite or dish television, septic tanks and links, and propane tanks or lines.
