This 1999 Freightliner FL112 is a sewer truck — sometimes called a vacuum truck or vac truck — a specialized vehicle used for the collection, transport, and disposal of liquid waste, sludge, and debris from sewer systems, lift stations, septic tanks, and industrial sites. Freightliner is a well-established American commercial truck manufacturer with a long history of producing heavy-duty vocational and work vehicles for municipal, utility, and industrial applications.
The unit is mounted with a Keith Huber vacuum system operating on a liquid ring principle, a design widely used in sewer and industrial vacuum applications for its ability to handle wet and liquid-laden material efficiently. The truck carries a 3,500-gallon tank, providing substantial capacity for demanding collection work. The tank is built with 316L stainless steel wetted parts, a corrosion-resistant alloy well suited to the aggressive chemical environments encountered in sewage and industrial liquid service. An electric vibrator is fitted to assist in material discharge and prevent solids from bridging or settling within the tank. A walkway with an access ladder is installed on the tank, allowing operators safe and practical access to the top for inspection, maintenance, and operational tasks.
The water package delivers 10 GPM at 2,500 psi, giving the truck a high-pressure jetting capability useful for dislodging blockages, cleaning sewer lines, and flushing debris ahead of vacuuming.
This used unit is located in Indiana, USA, and is offered at $23,900.
