The Sinotruk HOWO 22cbm vacuum jetter truck is a 12,000 litre combined sewer cleaning vehicle built on a 4x2 chassis with a 371 HP diesel engine and 10-speed manual gearbox. It is designed for municipal sanitation departments and waste contractors that need to clear blockages in sewage pipelines using high-pressure jetting and then remove debris and sludge via powerful vacuum suction. The truck operates in urban and rural environments where sewer access is limited and maintenance cycles must be fast and reliable. It is deployed in regions like Somalia where infrastructure is underdeveloped and waterborne waste must be managed without reliance on centralised treatment plants.
