Before You Dig


New Mexico excavation law places certain responsibilities with the excavator for preventing damage to underground facilities. “Excavator” includes one person with a shovel as well as heavy equipment. The law provides for a one-call system that the excavator can use free of charge to arrange to have underground facilities located and marked before an excavation occurs.

When you call for a locate, it is your responsibility to ensure the information is properly recorded on the request.

To request a locate or to ask questions about what is required, contact New Mexico One Call Toll Free at 811 or submit a request online at NM 811 website.
