It’s common for technical industries to develop their own jargon over time. Jargon is complex industry-specific language used in a particular trade, profession, group, or field of study. Sometimes jargon can be seen as convoluted or excluding, but it’s often necessary to communicate specific technical information.
Here are some common and uncommon words and phrases that you may come across when researching or communicating about utility locating, concrete imaging, leak detection, CCTV video pipe inspection, and more. Note that these are broad definitions meant to clarify the essential meaning for an average reader.

Ground Disturbance Plan: A ground disturbance plan is a consultation that denotes the rules and regulations of one should penetrate the ground, often referred to as an excavation safety policy.
KMZ: Map locations are stored in zip-compressed KML format that can be viewed in various geographic information system (GIS) applications. Features can be recorded as points, lines, or polygons. Various information can be attached to these such as photos, descriptions, coordinates, and more.
Lateral Launch Camera: A video tool used as a sewer inspection system that allows private utility locator technicians to inspect laterals from the sewer mainline. This service can perform cross bore investigations and map the interior condition of hard-to-reach pipes.
Leak Detection: A service provided by private companies where leak detection technicians use specialized leak detection equipment to locate subsurface pipe leaks.
Leak Detection Specialist: GPRS refers to our leak technicians as Leak Detection Specialists.
Leak Noise Correlator: Leak Detection Correlators are specialized electronic devices used to locate leaks in water lines and pipes. Sensors are placed on both sides of the pipe. These sensors send information to each over via radio. An automated process identifies each suspected leak location and displays it on the main control unit.
Line: Often, wires, pipes, and other utilities that run under the ground are called lines.
Locate: In the GPR industry, locate is often used as a noun. Public and private locators refer to their locating projects as a locate.
Magnetometers: Instruments that detect magnetic fields from ferrous, metallic objects. Private companies will typically use it to detect isolated, metallic objects such as USTs, valves, manholes, and wellheads.
Mainline Inspection: An inspection on the main sewer line, typically through VPI or Video Pipe Inspection services.
Manhole Inspection: These inspections are investigation processes to ensure the integrity and safety of a sewer manhole.
Monitoring Wells: A well that is designed and installed for obtaining representative groundwater quality samples. Typically to monitor and detect seepage and groundwater quality near a storage or treatment facility that stores agricultural waste.
NASSCO: The National Association of Sewer Service Companies is an industry source for trenchless technology education, resources, and advocacy.
NDT: Non-Destructive Testing is a method of investigation which allows subsurface locators to examine an area without digging, coring, concrete cutting, concrete sawing, trenching, excavating, or otherwise disturbing an area.
Non-Revenue Water: Water leaking from water line infrastructure before it reaches a private water meter, accruing costs for the water distribution facilities.
Phase I Investigation: Phase I Environmental Site Assessments (Phase 1 ESAs) are due diligence investigations used to assess whether hazardous materials are present on a property and determine the risk to prospective purchasers, owners, operators, insurers, and lenders.
Phase II Investigation: Phase II ESAs typically consist of collecting soil, soil gas, vapor intrusion samples, and groundwater samples and then sending these to a lab to determine whether the operations have caused environmental contamination.
Post-Tension Cables: Concrete construction uses post-tension cables to enable thinner slabs and longer spans between columns. Cables made of steel wires encased in plastic sheaths are tensioned and grouted after the concrete is poured.
Project Manager: At GPRS, we refer to our certified technicians as Project Managers. This differentiation is implemented to set them apart and to denote their capabilities to oversee customer projects in their entirety.
Push Camera: A small camera system can be manually fed into pipes smaller than 6 inches. Each camera is equipped with a sonde to locate the pipe, laterals, and obstructions and the ability to record video.
