What Are Vacuum Truck Services?
Vacuum trucks (also called vac trucks or combination trucks) are specialized vehicles equipped with high-powered vacuum systems and often combined with pressure jetting capabilities. They're essential for drainage jobs that require removing large volumes of water, sludge, gravel, or debris from underground systems.
Types of Vacuum Trucks
- Hydro-vac trucks — combine high-pressure water with vacuum for precision excavation
- Combination trucks — jetting + vacuum for drain cleaning and material removal
- Straight vacuum trucks — pure suction for liquid and sludge removal
Common Applications
Catch Basin and Storm Drain Cleaning
Municipal and commercial catch basins accumulate sediment, debris, and pollutants. Regular vacuum cleaning prevents flooding and maintains stormwater system capacity. Most municipalities require annual or semi-annual cleaning.
Sewer Line Maintenance
Large-diameter sewer mains require vacuum trucks to remove debris loosened by jetting. This is standard practice for municipal infrastructure maintenance.
Emergency Flood Response
When basements flood or storm systems overflow, vacuum trucks can remove standing water rapidly. Time is critical to minimize damage — a vacuum truck can remove thousands of litres per hour.
Hydro Excavation (Daylighting)
Vacuum trucks using pressurized water to excavate soil are the safest method for exposing underground utilities. This "soft dig" approach prevents damage to gas lines, electrical conduits, and telecommunications cables.
Septic Tank Pumping
Properties not connected to municipal sewer rely on septic systems that require periodic pumping. Vacuum trucks remove accumulated solids from the septic tank.
Construction Site Dewatering
Excavation sites often encounter groundwater that must be removed to continue work. Vacuum trucks provide rapid dewatering capabilities.
