This 2016 Western Star 4700 Sewer Truck is a used sewer truck — sometimes referred to as a vacuum truck or jetter truck — designed for municipal and industrial wastewater work, including the cleaning, jetting, and vacuuming of sewer lines, catch basins, and related drainage infrastructure. Western Star is a well-established North American heavy-truck manufacturer known for producing robust, vocationally-spec'd trucks built to handle demanding applications across construction, municipal, oil and gas, and utility industries.
The truck is equipped with a Challenger vacuum pump, model 866-FD, which forms the heart of the sewer cleaning system and enables high-capacity suction for removing debris, solids, and liquid waste from pipelines and catch basins.
On the drivetrain and chassis side, this unit is configured with an inter-axle lock, a differential lock, and an axle lock, providing substantial traction capability when operating on soft ground, muddy job sites, or uneven terrain — conditions commonly encountered in sewer and utility work. A three-stage engine brake is fitted, offering progressive retardation control that is particularly valuable when operating a loaded vacuum truck on grades or in urban environments. The axle ratio is 4.10, a specification that reflects a balance between pulling power and operational road speed appropriate for a vocational truck of this type.
Additional features include heated mirrors for cold-weather visibility — a practical consideration given the machine's location in Minnesota — and a trailer air brake valve, indicating the truck is equipped to tow a braked trailer when required.
This machine is priced at $78,500 and is located in Minnesota, USA.
