Utility locator tool in use (Perry, Oklahoma, 2011) Utility location is the process of identifying and labeling public utility mains that are underground. These mains may include lines for telecommunication, electricity distribution, natural gas, cable television, fiber optics, traffic lights, street lights, storm drains, water mains, and wastewater pipes.
Cable locator. A cable locator or cable avoidance tool ( CAT) is an instrument used for detecting the presence and approximate location of buried services in advance of undertaking excavation works. It aims to avoid accidents while excavating. [1] A number of types of detecting technology can be employed by such instruments, including use of ...
Directional boring. Directional boring, also referred to as horizontal directional drilling ( HDD ), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig.
Underground Service Alert ( USA) is a non-profit mutual benefit organization that links the excavation community and the owners of underground lines. Underground Service Alert has two separate call centers for California: Underground Service Alert of Northern California (USA North) and Underground Service Alert of Southern California (USA South ...
National Electrical Safety Code. The National Electrical Safety Code ( NESC) or ANSI Standard C2 is a United States standard of the safe installation, operation, and maintenance of electric power and communication utility systems including power substations, power and communication overhead lines, and power and communication underground lines.
Subsurface utility engineering (SUE) refers to a branch of engineering that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, communication of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation ...
Locators have been known to miss some of the buried utilities or be unable to completely or accurately mark a site because there are many overlapping buried utility lines. For these reasons, vacuum excavation can be an effective way to find, with virtually 100% accuracy, all underground structures in an excavation zone.
The US Safe Drinking Water Act and derivative legislation define a "public water system" as an entity that provides " water for human consumption through pipes or other constructed conveyances to at least 15 service connections or serves an average of at least 25 people for at least 60 days a year."

A utility tunnel, utility corridor, or utilidor is a passage built underground or above ground to carry utility lines such as electricity, steam, water supply pipes, and sewer pipes. Communications utilities like fiber optics, cable television, and telephone cables are also sometimes carried. One may also be referred to as a services tunnel ...
A chart showing different underground utility locating cart systems. 3D mapping can be accomplished when several individual passes are combined and interpolated. All of the systems and antennas manufactured by US Radar are capable of having their data presented in 3D format with the appropriate software packages.
