Hydroexcavation technology continues to grow in popularity among municipalities. New tools for jetting and hydroexcavating, including trucks, trailers and nozzles, serve a variety of functions, from the elimination of wastewater, roots and grease, to removing paint and other coatings from surfaces, to exposing and cutting pipe. Here is a look at some of the latest technology.

Jet/Vac Combination Trucks/Trailers

Truck vacuum excavator

The FXT50 truck vacuum excavator from Ditch Witch mounts directly to a truck’s frame rails, allowing the system to flex independently of the truck. A dealer will mount the unit to the single-axle truck of the customers’ choosing, and can customize the truck with toolboxes and other support equipment, such as a 1,020 cfm blower, and 3,000 psi water system flowing 5 gpm. 800/654-6481; www.ditchwitch.com.
