When anyone digs in Texas, whether planting a tree or digging the foundation of a skyscraper, there is a high probability of an underground utility line being within the dig site.  Hitting an underground utility line does more than interrupt utility service; it risks the safety of the person digging and the public. 


Texas law requires homeowners to contact 811 two business days (excluding weekends and holidays) before digging, even if you’re working in your own backyard. 

Homeowners should contact 811 when:

Any chore or maintenance that requires digging

If you are hiring a contractor to do the work for you, it is the contractor’s responsibility to contact 811 two business days prior to digging. You may want to make sure your contractor has notified 811 before the work begins by requesting the ticket number.

811 is a FREE service!

There is no cost to you to contact 811 to find out where your underground utility lines are.

There are two ways to request to have your lines marked.

We'd love to hear from you

Both methods are free of charge and available 24/7/365.

By phone at 811.

Listen carefully to the recorded message.

You can use the online Homeowner Portal.

The Portal is a program that walks homeowners through the process step-by-step program.
