The Sinotruk HOWO 18-ton septic vacuum truck is a 18,000 litre waste collection vehicle built on a 6x4 chassis with a 336 HP diesel engine and 10-speed manual gearbox. It is designed for municipal sanitation departments, waste contractors, and public works fleets that need to collect and transport human waste, sludge, and small solid debris from septic tanks, toilets, and blocked drains. The truck operates in urban, rural, and industrial areas where sewer access is limited or unavailable. It features a vane-type vacuum pump with a 318 m³/h pumping speed and suction depth of up to 8 metres, allowing it to extract waste from deep or clogged systems without requiring a secondary pump.
