Combination Trucks for Sewer & Storm Drain Cleaning
Sewer and storm drain cleaning is the removal of grease, sediment, roots, and debris that build up inside sanitary sewer lines, storm drains, and culverts and restrict or block flow. The standard equipment is a combination sewer truck, which pairs a high-pressure water jetting system that scours and dislodges buildup with a powerful vacuum that removes the loosened material and wastewater from the line.
Sewer mains and storm pipes clog over time as fats, oils, grease, silt, and root intrusion accumulate along the pipe walls. Left unmanaged, this causes backups, overflows, and flooding. Routine jetting and vacuuming keeps lines flowing, and the same equipment is used for emergency unblocking, pre-inspection cleaning before CCTV camera work, and post-construction cleanup.
How the equipment is used
A combination (combo) truck cleans a pipe in two coordinated steps. First, the operator feeds a jetting hose with a specialized nozzle into the line, and pressurized water propels the nozzle upstream while its rear-facing jets blast grease, roots, and sediment off the pipe walls and flush the debris back toward an access point such as a manhole. Second, a large-bore vacuum hose lifts the dislodged slurry and wastewater out of the manhole or catch basin into the truck's debris tank. Many combo units recycle water from the debris tank back through the jetting system, which extends how long the truck can work between refills. A straight vacuum truck can handle the removal side when a separate jetter is already on site, and heavy, sediment-laden storm lines may call for added vacuum capacity.

Sewer & Storm Drain Cleaning FAQ
What truck is used to clean sewer and storm drain lines?+
A combination sewer truck, also called a combo truck, is the standard. It combines high-pressure water jetting that scours the pipe walls with a vacuum that removes the loosened debris and wastewater. It is used for sanitary sewers, storm drains, and culverts.
What is the difference between jetting and vacuuming a sewer line?+
Jetting uses pressurized water through a nozzle to cut and dislodge grease, roots, and sediment from the pipe walls, while vacuuming removes the loosened material and standing water out of the line. A combo truck does both, which is why it is the preferred single-unit tool for full sewer and storm cleaning.
Can the same truck clean both sanitary sewers and storm drains?+
Yes. A combination truck cleans sanitary sewer mains and laterals as well as storm drains, culverts, and catch basins. The nozzle, hose size, and technique are adjusted to the pipe diameter and the type of buildup. Describe your line sizes and blockage in your request so companies can match a suitable unit.
