Case Study and Acceptance Criteria Interpretation for Suizhou 3308 Yellow-Plate Sewage Treatment Vehicle in Government Procurement. In municipal sanitation, sewage treatment vehicles—integrating sewage collection, solid-liquid separation, and purification—are critical for handling septic tanks, rivers, and industrial wastewater. In 2025, a district Urban Management Bureau procured Suizhou 3308 yellow-plate sewage treatment vehicles via public tender, with a budget cap of approximately RMB 388,000 per unit and an average unit price of around RMB 310,000 (based on publicly available tender information). Chengli Special Purpose Vehicle Co., Ltd., as the winning supplier, delivered two units of this model; customer feedback confirms stable operational performance to date. This article uses this case as a starting point to detail the 10 mandatory inspection items upon vehicle delivery, methods for verifying MIIT (Ministry of Industry and Information Technology) parameters, Chengli’s delivery process assurance measures, and frequently asked questions—providing procurement entities with a professional guidance manual. I. Ten Mandatory Inspection Items Upon Vehicle Delivery In government procurement, the acceptance phase is critical to ensuring equipment quality and regulatory compliance. Based on Chengli Special Purpose Vehicle’s delivery to the district Urban Management Bureau, we have compiled the following 10 mandatory inspection items to ensure full conformity with tender requirements. 1. Chassis Information Verification: Confirm chassis brand, model, and VIN number against the contract. The Suizhou 3308 yellow-plate sewage treatment vehicle typically employs Dongfeng or Sinotruk chassis; original factory nameplates and certificates of conformity must be verified. 2. Engine and Emission Standard Verification: Verify engine model, rated power, and China VI emission certification label. All Chengli models comply with China VI standards; on-site data can be read via the OBD interface. 3. Tank Body and Material: Inspect tank capacity (commonly 8–12 m³), material (carbon steel or stainless steel), and uniformity of anti-corrosion coating—ensuring no bubbles or rust spots. Measured tank wall thickness must meet 4–6 mm specifications. 4. Sewage Treatment System: Test operation of solid-liquid separation equipment, water pumps, and vacuum pumps. A no-load run of 10 minutes is required; observe for abnormal noise, leakage, or vibration. 5. Electrical System and Instruments: Check functionality of control panels, liquid level indicators, pressure gauges, and indicator lights. Power-on testing of all function keys is mandatory. 6. Hydraulic System: If equipped with hydraulic lifting or self-dumping functions, verify smooth cylinder extension/retraction and absence of hydraulic oil leakage from hoses. 7. Tires and Braking System: Inspect tire model, inflation pressure, and tread wear; test brake system response time. 8. Safety Devices: Verify presence and compliance of fire extinguishers, warning lights, reflective markings, and emergency stop buttons per GB 7258 standard. 9. Accompanying Documentation: Confirm completeness of Certificate of Conformity, warranty card, user manual, chassis manual, and official announcement page. 10. Exterior Appearance and Paint Finish: Inspect uniformity of body paint, absence of scratches, and clarity of branding (e.g., 'Chengliwei'). Note: During acceptance, it is recommended to bring the tender documents, contract, and official announcement parameter sheet for item-by-item verification to avoid omissions. II. Methodology for Verifying MIIT Parameters In government procurement, vehicles must strictly conform to technical parameters published in the MIIT’s 'Announcement of Road Motor Vehicle Manufacturers and Products'. For example, Chengli’s product models—including CLW5070GSSD6 (water-sprinkling vehicle)—are listed in the Announcement and searchable online. Below are the verification steps: 1. Query
