## Glossary

- [Glossary hub](https://www.hydrovachotline.org/glossary): Definitions for hydrovac, vacuum-excavation, and underground-utility-safety vocabulary.
- [811 (One-Call System)](https://www.hydrovachotline.org/glossary/811): 811 is the federally mandated number for requesting underground utility marks before excavation in the United States. Each state has its own 811 program; calling notifies all member utilities to mark their buried lines on the dig site.
- [APWA Color Code](https://www.hydrovachotline.org/glossary/apwa-color-code): The American Public Works Association's uniform color code for marking underground utilities. Red=electric, yellow=gas/oil, orange=communications, blue=potable water, green=sewer, purple=reclaimed water, pink=temporary survey, white=proposed excavation.
- [Bell Hole](https://www.hydrovachotline.org/glossary/bell-hole): An excavation around a buried pipeline, sized to provide working room for inspection, repair, or tie-in welds. Bell holes are commonly excavated with hydrovac to avoid damaging pipe coatings.
- [Cathodic Protection](https://www.hydrovachotline.org/glossary/cathodic-protection): An electrochemical method of preventing corrosion on metal pipelines and structures. Damaged pipe coatings can compromise cathodic protection — one reason pipeline operators prefer hydrovac for any work near coated pipe.
- [Combo Truck](https://www.hydrovachotline.org/glossary/combo-truck): A vacuum truck combining hydrovac excavation with sewer-cleaning capability. Most commercial hydrovac contractors run combo trucks because they handle the widest range of jobs.
- [Daylighting](https://www.hydrovachotline.org/glossary/daylighting): The practice of safely exposing buried utilities at the surface to verify their location and depth. Synonymous with potholing; both refer to controlled, non-destructive excavation that reveals what's underground.
- [Debris Tank](https://www.hydrovachotline.org/glossary/debris-tank): The on-board tank where a hydrovac truck stores excavated material (water-soil slurry). Standard combo-truck capacity is 10-12 cubic yards; dedicated hydroexcavators run 12-16 yards.
- [FBE Coating (Fusion Bonded Epoxy)](https://www.hydrovachotline.org/glossary/fbe-coating): A protective coating applied to steel pipelines by heating epoxy powder onto the pipe surface. FBE provides corrosion resistance and electrical insulation; damage from mechanical excavation is the most common preventable threat to this coating.
- [Frost Depth](https://www.hydrovachotline.org/glossary/frost-depth): The maximum depth at which ground freezes in winter. Frost depth varies from 0 inches (warm climates) to 60+ inches (northern Minnesota, Canadian Prairies). Hydrovac trucks with heated water systems can excavate through frozen ground when conventional digging cannot.
- [GPM (Gallons Per Minute)](https://www.hydrovachotline.org/glossary/gpm): A measure of water flow rate. Hydrovac trucks pump 25-80 GPM at the dig site. Higher GPM moves more spoil faster but consumes water more quickly, requiring more frequent refills.
- [Heated Water System](https://www.hydrovachotline.org/glossary/heated-water-system): A boiler or heat-exchanger system on a hydrovac truck that warms the cutting water. Heated systems allow excavation through frozen ground in winter and reduce energy losses to cold spoil during operation.
- [Hydroexcavator](https://www.hydrovachotline.org/glossary/hydroexcavator): A truck dedicated to hydrovac excavation (no sewer cleaning capability). Hydroexcavators typically have larger debris tanks and higher water pressure than combo trucks; common in oil & gas pipeline work.
- [Mobilization](https://www.hydrovachotline.org/glossary/mobilization): The cost of moving a hydrovac truck to and from a job site. Most providers charge for round-trip mileage beyond a 25-50 mile radius from their yard. Mobilization can rival or exceed hourly excavation cost on remote jobs.
- [MS4 (Municipal Separate Storm Sewer System)](https://www.hydrovachotline.org/glossary/ms4): EPA-regulated stormwater systems that municipalities operate. MS4 permits require ongoing maintenance, including catch basin and storm drain cleaning, with documented removal volumes for annual reporting.
- [One-Call](https://www.hydrovachotline.org/glossary/one-call): The general term for the system that notifies utility owners about planned excavation. In the US it's 811; in Canada it's a province-by-province network including Alberta One-Call, BC One Call, Info-Excavation (Quebec), and Ontario One Call.
- [Pipeline Exposure](https://www.hydrovachotline.org/glossary/pipeline-exposure): The process of safely uncovering a buried pipeline for inspection, repair, or modification. Hydrovac is the standard method because it preserves protective coatings and avoids strike damage.
- [Potholing](https://www.hydrovachotline.org/glossary/potholing): Creating a small, precise excavation to expose and verify the location of a buried utility. Synonymous with daylighting. Hydrovac potholing is the gold standard for utility verification before mechanical excavation.
- [PSI (Pounds Per Square Inch)](https://www.hydrovachotline.org/glossary/psi): A unit of pressure. Standard hydrovac water pressure is 2,000-3,000 PSI. Higher pressures (up to 5,000 PSI) are used for hard soil, but operators reduce pressure when working near pipe coatings or thin-walled utilities.
- [Recycling Unit](https://www.hydrovachotline.org/glossary/recycling-unit): A hydrovac truck that filters, cleans, and reuses water on-board, dramatically reducing water consumption and disposal volume. Higher upfront cost but lower per-job operating cost on long or remote projects.
- [Rotary Nozzle](https://www.hydrovachotline.org/glossary/rotary-nozzle): A spinning nozzle tip that distributes water pressure across multiple cutting points. Rotary nozzles are the workhorse for general hydrovac excavation in mixed soil conditions.
- [Slot Trenching](https://www.hydrovachotline.org/glossary/slot-trenching): A narrow (6-12 inch wide) trench cut by hydrovac for utility installation. Slot trenches dramatically reduce surface restoration costs vs traditional open-cut trenching, especially in landscaped or paved areas.
- [Spoils](https://www.hydrovachotline.org/glossary/spoils): The mixture of water and excavated material in a hydrovac debris tank. Spoils handling and disposal — especially for hazardous or PFAS-affected material — is a meaningful cost component of any hydrovac project.
- [Storm Drain Cleaning](https://www.hydrovachotline.org/glossary/storm-drain-cleaning): Vacuum-truck removal of silt, debris, and sediment from storm sewer lines and culverts. Routine maintenance restores design flow capacity and supports MS4 compliance.
- [SUE (Subsurface Utility Engineering)](https://www.hydrovachotline.org/glossary/sue): An engineering practice for identifying and managing the location of buried utilities. Has four quality levels (A through D); Quality Level A — verified by physical exposure, typically via hydrovac potholing — is the highest standard.
- [SWPPP (Stormwater Pollution Prevention Plan)](https://www.hydrovachotline.org/glossary/swppp): A site-specific plan documenting how a construction or industrial site will prevent stormwater pollution. Catch basin and storm drain cleaning by hydrovac is a common SWPPP best management practice.
- [Tolerance Zone](https://www.hydrovachotline.org/glossary/tolerance-zone): The buffer area around a marked utility within which mechanical excavation is prohibited. Most state programs define this as 18-24 inches in any direction. Soft-dig methods (hydrovac, hand-digging) are required within the tolerance zone.
- [Utility Locating](https://www.hydrovachotline.org/glossary/utility-locating): The process of detecting and marking buried utilities using electromagnetic locators, ground-penetrating radar, and One-Call records. Often paired with hydrovac potholing for physical verification at depth.
- [Utility Strike](https://www.hydrovachotline.org/glossary/utility-strike): Damage to a buried utility caused by excavation. Strikes range from coating nicks ($1,000+) to gas main ruptures ($1M+ plus injuries). Hydrovac's non-contact method dramatically reduces strike risk.
- [Vacuum Truck](https://www.hydrovachotline.org/glossary/vacuum-truck): A truck that uses an industrial vacuum to extract material — liquid, solid, or slurry. Hydrovac trucks are a specialized class of vacuum truck that pairs high-pressure water with the vacuum system for excavation.
- [Water Pump](https://www.hydrovachotline.org/glossary/water-pump): The high-pressure pump on a hydrovac truck. Standard configuration is a triplex pump producing 2,000-3,000 PSI at 25-80 GPM. Heavy-duty oil & gas applications use plunger pumps to 5,000 PSI.
- [Catch Basin](https://www.hydrovachotline.org/glossary/catch-basin): A storm-water inlet at a curb or low point with a sumped chamber that collects sediment before water enters the storm sewer. Routine catch basin cleaning by vacuum truck is the most cost-effective preventative maintenance in any storm-water program.
- [Fiber Buildout](https://www.hydrovachotline.org/glossary/fiber-buildout): The deployment of fiber-optic cable infrastructure across a service area. Typically uses a combination of slot trenching (with hydrovac), microtrenching, and aerial installation. One of the largest growth segments for commercial hydrovac demand.
- [Microtrenching](https://www.hydrovachotline.org/glossary/microtrenching): A trench-cutting method using a saw to cut a 1-2 inch wide slot in pavement for fiber installation. Faster than hydrovac slot trenching but limited to hard surfaces; the two methods are complementary on most fiber buildouts.
- [PFAS (Per- and Polyfluoroalkyl Substances)](https://www.hydrovachotline.org/glossary/pfas): A class of persistent industrial chemicals increasingly regulated as environmental contaminants. PFAS-affected spoils require specialized disposal, adding cost and logistical complexity to any hydrovac project on contaminated sites.
- [Climate Zone](https://www.hydrovachotline.org/glossary/climate-zone): A regional classification based on temperature and moisture patterns (humid subtropical, continental, arid, etc.). Affects hydrovac operations through frost depth, soil moisture, and seasonal scheduling considerations.
