Government Procurement Case and Configuration Solution Analysis for the New Dongfeng Sewage Treatment Vehicle in Jinhua, Zhejiang Province Recently, the Urban Management Bureau of a district in Jinhua City, Zhejiang Province (hereinafter referred to as the 'procuring entity') issued a public tender to procure a batch of new Dongfeng-chassis sewage treatment vehicles, addressing local river and domestic sewage treatment needs. After multiple rounds of technical evaluation and price negotiation, Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli') was selected as the supplier. Based on this case, this article analyzes core considerations for such government procurement projects from four perspectives: comparison between standard and premium configurations, value analysis of optional accessories, Chengli’s transparent pricing logic, and frequently asked questions. I. Standard vs. Premium Configuration Comparison Per the procuring entity’s requirements document, the vehicles must fulfill functions including routine sewage suction, transportation, and rapid on-site treatment, while also meeting explicit criteria regarding chassis stability, emission standards (China VI), and upper-structure durability. Chengli offered two configuration options—both built on Dongfeng chassis (e.g., model CLW5070GSSD6 per official announcement parameters)—with primary differences lying in upper-structure treatment capacity and added functionalities. The detailed configuration comparison is shown below: Configuration Item | Standard Version (5-m³ Sewage Treatment Vehicle) | Premium Version (8-m³ Sewage Treatment Vehicle) ---|---|--- Chassis Brand | Dongfeng Light-Duty Truck (China VI Emission Standard) | Dongfeng Medium-Duty Truck (China VI Emission Standard) Tank Capacity | Approx. 5 m³ (per CLW5070GSSD6 reference) | Approx. 8 m³ Sewage Treatment Capacity | Basic filtration + sedimentation system; treatment capacity approx. 10 m³/h | High-efficiency filtration + disinfection system; treatment capacity approx. 20 m³/h Suction Pump | Conventional vacuum pump; suction lift ≤6 m | High-flow vacuum pump; suction lift ≤8 m Control System | Manual operation | PLC automatic control + remote monitoring interface (pre-installed) Optional Features | None | High-pressure cleaning gun (for pipeline unclogging) Reference Unit Price (Tax-Inclusive Landed Cost) | Approx. RMB 98,000–115,000 (based on Chengli’s 2026 pricing) | Approx. RMB 145,000–178,000 (based on Chengli’s 2026 pricing) Delivery Lead Time | 7–15 days | 15–20 days Note: Above prices are estimated based on Chengli’s 2026 tax-inclusive landed price range; actual contract terms shall prevail. Configuration differences primarily stem from tank volume and treatment system upgrades; the premium version is better suited for high-volume treatment scenarios. II. Value Analysis of Optional Accessories The procuring entity explicitly listed several optional accessories in its tender documents. Based on real-world operational conditions, Chengli recommended the following core optional accessories and assessed their cost-effectiveness: • Automatic Hose Reel (approx. RMB 2,000): Enables rapid deployment and retrieval of suction hoses, significantly reducing manual labor time. In high-daily-throughput operations, it can save approximately 30% of operational time, offering a short payback period. • Freeze Protection & Thermal Insulation System (approx. RMB 5,000): Designed for winter operations in northern or mountainous regions to prevent freezing of tanks and water lines. Although Jinhua experiences only occasional low temperatures in winter, the procuring entity opted to install this system to mitigate equipment failure risks. • GPS Tracking Terminal (approx. RMB 800): Meets requirements for fleet dispatching and operational route logging. Chengli recommends its OEM-compatible unit, which seamlessly integrates with local smart sanitation platforms. • Extended Spare Parts Kit
