Utility Designation | Our Services | WithersRavenel

Utility Designation

Using electromagnetic (EM) equipment and active or passive methods, WithersRavenel can designate conductive utilities such as copper telephone wire, coaxial cable, fiber optic cable, metallic water and sewer line, and gas line. Active methods are used for known utilities and involve selecting an EM frequency, inducing a signal directly in the line or indirectly in the ground around the line, and detecting the signal re-radiated by the utility. Passive methods are used for unknown utilities and involve sweeping the area with a receiver looking for anything that radiates or re-radiates frequencies.

Using Ground Penetrating Radar (GPR) equipment, WithersRavenel can designate non-conductive utilities and structures such as asbestos concrete pipe (ACP), reinforced concrete pipe (RCP), Polyvinyl Chloride (PVC) pipe, and underground storage tanks (USTs).
