How Do Vacuum Trucks Work?

Whenever your city or community’s sewage system clogs up or is starting to show signs that it’s about to, your local government will send out vacuum trucks to take care of the problem, as they are a much easier solution to sanitation problems than relying solely on manpower. So how exactly do these cleaning machines work?

The Business End

Vacuum trucks are named after their vacuum unit, which is usually mounted on the bed of the truck. This is powered by a pump that runs on a power take-off (PTO) system that is in turn powered either by the car’s engine or a completely separate motor.

Vacuum Truck Parts

There are many types of vacuum trucks, which mostly differ based on the function of their various parts. Some are equipped with the common hydraulic system with a hose and nozzle kit, whereas others have additions that are meant to improve the efficiency of the work done. Such additions include ladders, catwalks, and railings for easy access to the pump and the tank.


While septic waste management is one of their most common uses, vacuum trucks have other functions too, particularly when it comes to industrial work. They can serve to remove soil and other debris from construction projects or drill sites. Basically, as long as it’s loose enough to be pumped out, vacuum trucks can take care of it.
