Project Background: A sewage treatment vehicle procurement case by a municipal sanitation department in Jiujiang City. By the end of 2025, the Urban Management Bureau of a district in Jiujiang City, Jiangxi Province, planned to procure a batch of 3308 yellow-plate sewage treatment vehicles to enhance local sewage pipeline management capabilities. According to publicly released tender information, the project budget was capped at approximately RMB 1.2 million (unit price ranging from RMB 332,000 to RMB 387,000), requiring three special-purpose vehicles compliant with China VI emission standards for urban sewage suction, transportation, and preliminary treatment. After multiple rounds of evaluation, Chengli Special Purpose Vehicle Co., Ltd. successfully delivered three CLW5070GSSD6 yellow-plate sewage treatment vehicles (reference announcement model) based on its mature product solution and comprehensive after-sales service. This article, drawing on this case and from the perspective of government procurement acceptance, summarizes the 10 essential items to verify upon vehicle receipt, outlines the method for verifying parameters listed in the Ministry of Industry and Information Technology (MIIT) announcement, and explains how Chengli’s delivery process ensures compliance—providing practical guidance for other municipal authorities. I. Ten Essential Items to Verify Upon Vehicle Receipt Based on the acceptance records of the Jiujiang procurement unit and Chengli Special Purpose Vehicle’s delivery standards, the following ten items must be rigorously verified upon receipt to ensure regulatory compliance and operational readiness: 1. Chassis Brand and Model Verification: Confirm that the chassis is from an approved brand such as Dongfeng or Sinotruk (in this case, Dongfeng 3308 chassis), consistent with contractual specifications. 2. Engine Emission Standard: Inspect the engine nameplate to verify compliance with China VI emission standards (the CLW5070GSSD6 model carries official China VI certification). 3. Tank Capacity: Conduct on-site measurement of effective tank volume; for this sewage treatment vehicle (yellow-plate class), the tank capacity is approximately 8 m³, with allowable tolerance within ±5%. 4. Upper-Structure Function Testing: Includes verification of vacuum pump suction efficiency, tank sealing integrity, and proper operation of discharge valves (opening/closing functionality). 5. Hydraulic System Inspection: Check hydraulic lines for leaks and confirm smooth, responsive operation of control levers. 6. Lighting and Safety Markings: Ensure full functionality of headlights, turn signals, brake lights, side marker lights, and retroreflective markings. 7. Tires and Spare Tire: Verify tire model and inflation pressure conform to MIIT announcement parameters; spare tire must be present and complete. 8. Onboard Tools and Documentation: Must include vehicle conformity certificate, user manual, chassis warranty manual, and upper-structure operation manual. 9. Exterior Appearance and Paint Finish: Body surface free of scratches; uniform paint color (municipal logos may be customized per requirement). 10. Operational Test Run and Road Test: Conduct a 5-kilometer test drive within the factory premises to evaluate braking performance, steering responsiveness, and driving stability. II. Method for Verifying MIIT Announcement Parameters In government procurement, all vehicle technical parameters must strictly match those published in the MIIT’s 'Announcement of Road Motor Vehicle Manufacturers and Products'; non-compliance renders the vehicle ineligible for registration. Using the CLW5070GSSD6 model as an example, verification steps are as follows: 1. Locate the Announcement Number: Search for 'CLW5070GSSD6' in the MIIT’s official 'Announcement of Road Motor Vehicle Manufacturers and Products' to retrieve the complete parameter table. 2. Cross-Check Key Parameters: Including overall dimensions (approx. 6 m in length, 2 m i
