Will my private utility lines be marked? No. Member utilities companies are responsible to mark only the facilities that they own or maintain. Private underground pipes and cables may not be owned or maintained by member utility companies, therefore they are unable to locate them. Private utility lines are lines commonly between the meter and a home or utility lines that were installed by the home owner to out buildings, etc. It is your responsibility to investigate if any privately-owned utilities are in the area.
NM 811To get to your house and meter, utility must run lines on private property. By law, they are responsible for locating them, and you will be liable for repair if you damage them. Beyond the meter is all yours.
