Case Background: Procurement Requirement for Sewer Cleaning Trucks by a Municipal Sanitation Department in Ordos City. In 2024, a municipal sanitation department in Ordos City, Inner Mongolia, initiated a procurement plan for sewer cleaning trucks to conduct urban drainage pipe cleaning operations. Based on local procurement conventions, the budget was constrained to approximately RMB 311,000 per unit. The target vehicle was a Dongfeng dual-cab blue license plate sewer cleaning truck with a 3-cubic-meter tank capacity, compliant with China VI emission standards, highly maneuverable, and optimized for operation on narrow urban streets. Following an open tender process and comprehensive technical and commercial evaluation, Chengli Special Purpose Vehicle Co., Ltd. delivered two units of the Dongfeng dual-cab blue license plate sewer cleaning trucks (model reference: CLW5070GSSD6 series chassis conversion), with a total contract value of approximately RMB 265,000 (based on publicly available tender information). These vehicles are now fully operational; customer feedback highlights high operational efficiency, excellent turning agility, and reliable performance under Ordos’ harsh winter low-temperature conditions. Key Vehicle Configuration and Technical Specifications: The delivered vehicles are built upon a Dongfeng dual-cab chassis equipped with a China VI-compliant engine, satisfying Blue License Plate (Class C driver’s license) driving requirements. The tank features an effective capacity of 3 cubic meters and is integrated with a high-pressure cleaning system, vacuum suction system, and hydraulic lifting mechanism—enabling simultaneous flushing and suction functions. Key Technical Parameters (based on Chengli’s product database and MIIT official announcements): Chassis Model: Dongfeng EQ1075SJ3CDF (reference CLW5070GSSD6 announcement) Engine: Quanchai or Yuchai, China VI emission compliant Tank Capacity: 3 cubic meters Rated Payload: Approx. 1.5 tons Overall Dimensions (L×W×H): ~5.5 m × 2.0 m × 2.4 m Maximum Speed: 80 km/h Wheelbase: 3,308 mm Tire Specification: 7.00R16 The vehicle holds full MIIT certification (e.g., CLW5070GSSD6) and is eligible for nationwide registration, annual inspection, and road transport permit issuance. Government Procurement Strategy: Bulk Ordering and Cost Optimization This Ordos procurement involved a bulk order of two sewer cleaning trucks. Chengli adopted a direct factory sales model—eliminating intermediaries and associated markups. Drawing from comparable cases in the knowledge base (e.g., Henan sanitation bureau’s purchase of ten 5-cubic-meter water sprinklers), Chengli’s unit price is typically RMB 8,880–16,600 lower than 4S dealership channels. For this two-unit order, the procurement entity achieved cost savings of approximately RMB 20,000–30,000. In terms of delivery timeline, standard models can be manufactured within 7–15 days; combined with logistics from Suizhou, Hubei to Ordos, the total delivery cycle was completed within 20 days.
