A septic or vacuum truck makes its money at the stop, with the pump running and the hose in the tank. We wire the vacuum pump into the GPS tracker so every pump out shows up with a time, a place and a run time, for septic, portable toilet, grease trap and liquid waste haulers across Georgia, South Carolina, North Carolina, Tennessee, Virginia, Alabama, Florida and Mississippi.

A vacuum truck pulls air out of its tank with a vacuum pump. With the tank under vacuum, liquid and sludge are drawn up through the suction hose. Reversing the pump pressurizes the tank to push the load out at the disposal site. Septic pump trucks, portable toilet service trucks, grease trap trucks and industrial liquid vacuum trucks all work on the same idea, at different sizes.
On most trucks the vacuum pump is driven by a PTO from the transmission, either directly through a driveshaft or through a hydraulic pump and motor. Some larger industrial units use a separate engine. When the PTO is engaged, the pump is turning, so on most septic trucks PTO time is pumping time.
Truck side wire colors are in our Vehicle Wiring Database.
Disposal and service records matter in this trade. Many counties and states require septic haulers to keep records of where waste was collected and where it was disposed of. A tracked record of each pump out and each unload, with times and places, makes those records easier to keep and harder to dispute.
It also helps price the work. When owners see how long the pump really runs at different kinds of jobs, they can tell which calls are under-priced. And vacuum pumps, vanes and oil systems are serviced by run hours, which a tracker can count accurately while the truck sits still.
Septic service companies, portable toilet rental fleets, grease trap services, municipal utilities and industrial cleaning contractors. For one truck or fifty, the goal is the same: proof of every service stop and pump hours that keep the most expensive part of the truck maintained.
This is one of the work truck and equipment applications we wire into GPS trackers. See all of them on our PTO and equipment monitoring page, and find wire colors for your truck in our Vehicle Wiring Database.
We wire PTO monitoring into trackers from all of these brands. Need heavy duty trackers for trucks or heavy equipment? Every brand below makes them, so pick yours and we install it.
