HOWO Sewage Suction Truck 266 / 336 / 371 / 380 / 400HP 10 / 12 / 15 / 20 / 25CBM Available
HOWO Sewage Suction Truck is a heavy-duty vacuum tanker designed for collecting, transporting and discharging sewage, sludge, septic waste, wastewater and other liquid or semi-liquid waste. The vehicle combines a durable SINOTRUK HOWO chassis with a sealed vacuum tank, high-performance vacuum pump, suction pipeline, hydraulic lifting system and rear discharge structure for efficient sewage-handling operations. HOWO sewage suction trucks are available with 4×2, 6×4 and 8×4 chassis configurations. Engine options include approximately 266HP, 336HP, 371HP, 380HP and 400HP, while sewage tank capacities of approximately 10CBM, 12CBM, 15CBM, 20CBM and 25CBM can be configured according to chassis capacity, operating conditions and project requirements. The vacuum system creates negative pressure inside the tank and allows sewage, sludge and septic waste to be drawn through a large-diameter suction hose. Hydraulic tank lifting and an opening rear cover provide efficient discharge and easier removal of sediment or high-viscosity waste. Vacuum pump type, suction depth, hose diameter, tank material, tank thickness and discharge system can be customized.

Buyer Support
- HOWO Sewage Suction Truck combines a durable SINOTRUK HOWO chassis with a high-capacity vacuum sewage tank for municipal, industrial and construction wastewater applications. 4×2, 6×4 and 8×4 chassis configurations allow the vehicle to cover medium- and heavy-duty sewage collection requirements, while 266HP, 336HP, 371HP, 380HP and 400HP engine options provide sufficient power for loaded transportation and vacuum equipment operation. Approximately 10–25CBM tank capacities are available for different project requirements. Smaller configurations provide better maneuverability for urban and municipal work, while larger 6×4 and 8×4 versions provide greater sewage capacity for industrial sites, large septic tanks, mining camps and high-volume wastewater transportation. The PTO-driven vacuum pump creates strong negative pressure inside the sealed tank, allowing sewage, sludge and semi-liquid waste to be drawn through a large-diameter suction hose. Different vacuum-pump capacities can be selected according to tank size, required suction speed and waste characteristics. A maximum suction depth of approximately 6–8 meters allows the truck to service underground septic tanks, sewage pits, drainage structures and other locations below road level. Large-diameter 100–150mm suction hoses improve handling of sludge and higher-viscosity sewage. The hydraulic lifting tank and hydraulic rear door provide efficient unloading. When handling sediment, sludge or material that cannot be completely discharged through the outlet valve, the rear door can be opened and the tank hydraulically raised for direct dumping and easier internal cleaning. Anti-overflow devices, vacuum gauges, oil-water separators and gas-water separators help protect the vacuum pump and improve system reliability. Electronic liquid-level indicators, high-level alarms and additional protection devices can be added according to operating requirements. Carbon-steel tanks provide a durable and economical solution for municipal and general sewage applications, while stainless-steel tanks and corrosion-resistant internal coatings can be selected for projects requiring improved resistance to corrosive wastewater. Left-hand-drive and right-hand-drive configurations are available for different export markets. Tank capacity, tank material, vacuum pump, suction depth, hose diameter, hose length, hydraulic lifting system, rear-door structure, cleaning equipment, cameras, warning devices, paint color and other specifications can be customized according to project requirements.
