Combination (Combo) Truck

What is Combination (Combo) Truck?

A combination (combo) truck is a vacuum truck that pairs a high-pressure water jetting system with a powerful vacuum, used mainly to clean and clear sewers, catch basins, and wet wells and to recover the debris.

A combination truck (combo truck) combines sewer jetting, spraying high-pressure water down a line to dislodge blockages, with vacuum recovery that sucks the loosened sludge and water back into the debris body. Many units include a water recycling system that filters and reuses recovered water to extend runtime between fills.

Combo trucks are the workhorses of municipal sewer and stormwater maintenance, handling catch basin cleanout, wet well pumping, and pipe flushing. Some are also configured for hydro excavation.
