HOWO 6x4 17 m³ Vacuum Sewage Truck

This HOWO TX 6x4 vacuum sewage truck has a dedicated 17 m³ sewage tank and a separate 5 m³ clean-water tank. The water-ring vacuum pump draws liquid waste into the sewage compartment, while the clean-water supply serves the high-pressure cleaning system. A high-pressure pump is specified at 350 L/min for flushing work. The stated 17 m³ main capacity is the sewage tank alone; suction depth is confirmed with the final hose and pump configuration.

The three-axle chassis has a 25,000 kg gross vehicle weight and a 17,750 kg curb weight. A 257 kW (350 hp) engine drives the 6x4 layout through a manual transmission. Overall dimensions are 9,750 × 2,550 × 3,850 mm, and the wheelbase is 3,200 + 1,350 mm. The truck seats three people, uses 315/80R22.5 16PR tires and has a 300 L fuel tank. Axle ratings are 7,000 kg at the front and 18,000 kg across the rear group.

For sewer maintenance, the crew can use high-pressure water to break up deposits before vacuuming loosened sludge into the 17 m³ tank. Keeping clean water separate from collected waste helps the two systems work in sequence. The truck can also support septic and drainage service where access, waste type and disposal rules permit. Confirm suction depth, hose size, pump duty and the final vehicle mass for the planned service route.
