This 2024 Western Star 49X is a used sewer truck — sometimes referred to as a vacuum excavator or hydrovac truck — configured for hydro excavation work. Sewer trucks of this type use high-pressure water and powerful vacuum systems to excavate soil, clear lines, and remove debris in utility, municipal, and construction applications. Western Star is a well-established North American commercial truck manufacturer known for producing heavy-duty vocational and highway trucks built to demanding specifications, and this unit is located in Minnesota, USA, listed at $598,500.
The machine is bodied with a Rival T10 Hydrovac unit, a purpose-built mid-size hydro excavation body that Rival Hydrovac Inc. introduced in 2018 to meet demand for a larger-capacity follow-up to their T7 tandem. The T10 requires 450 or more horsepower from the carrier chassis and is designed around a 10-cubic-yard debris tank paired with a 1,200-US-gallon water tank, giving it substantial capacity for extended operation between offloads and refills.
The vacuum system is powered by a transfer-case-driven Robuschi 125 blower, ensuring the blower draw is directly tied to the chassis drivetrain for consistent performance. Filtration is handled through a combined cyclone and cartridge system to protect the blower and manage debris-laden airflow. The water pump is an Interpump T2040, and hydraulics are supplied by a Bosch Rexroth system. A Dynablast diesel-fired boiler rated at 420,000 BTU and operating on 12-volt power supports hot-water operation, which is particularly valuable in cold-weather conditions.
The debris tank offloads via a three-stage Mailhot hoist and pressure-off system, and the dump door is a full-opening design secured with Raptor locks. Two six-inch heated valves and a water tank level gauge with sight glasses round out the tank and valve configuration. The boom system measures eight inches in diameter, provides 340 degrees of rotation, and extends to 25 feet of reach, offering substantial flexibility for positioning on a job site. The Hannay hose reel is air-operated, and the entire unit is managed through an Aarcomm wireless remote system that includes a real-time weight display for load monitoring.
Cold-climate readiness is a clear priority in this specification. Winterization features include the aforementioned heated valves, a glycol blowdown system, custom insulated valve covers, heaters within the storage cabinets, air blowout provisions for the boiler coils and associated plumbing, and heat-traced water supply lines. Storage on the unit includes multiple frame rail toolboxes, a sign box, and a coat cabinet. Lighting is provided by front and rear beacons.
