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 ...
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.
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 ...
It is used during project development and is a major component of Subsurface Utility Engineering (SUE). The second concept is how to specify the recording of utilities exposed during their installation or during maintenance/repair operations so that future records are reliable. It is used primarily during utility installation.
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.
Ground-penetrating radar ( GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. [1]
Drinking water quality in the United States is generally safe. In 2016, over 90 percent of the nation's community water systems were in compliance with all published U.S. Environmental Protection Agency (US EPA) standards. [1] Over 286 million Americans get their tap water from a community water system. Eight percent of the community water ...
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 ...
