Thank you for reporting the issue. It is logged as request #15-001496 and has been forwarded to our Utility Coordinator. I will post his response once I receive it.

Private irrigation lines are not protected utilities when placed in a public right of way. However, AT&T may still make the repairs. The contact is below:

It was actually the main supply line from the irrigation meter to the house. Not an installed irrigation system. That said the installers were out today and repaired it. Thanks for following up.

Glad to hear it was repaired. Thank you!
