Handan Dongfeng Yizhan-Style Sewage Treatment Vehicle Government Procurement Case and Bid-Winning Solution Analysis In the second half of 2025, a municipal sanitation department in Handan City publicly tendered for a batch of Dongfeng Yizhan-style sewage treatment vehicles, intended for emergency response and routine maintenance of urban rivers and sewage pipelines. The project budget was capped at approximately RMB 1.984 million, with plans to procure six units at an estimated unit cost of around RMB 331,000. Multiple enterprises participated in the tender, including Chengli Special Purpose Vehicle Co., Ltd., which ultimately won the bid with its comprehensive proposal and has since completed delivery and commissioning. Below is a complete case analysis of this procurement. I. Project Background and Procurement Requirements As a key city in North China, Handan has faced mounting environmental protection pressures in recent years, with frequent blockages occurring in aging sewage pipelines. In Q3 2025, the municipal sanitation department launched this procurement initiative, specifying the following core requirements: • Chassis: Dongfeng Yizhan model, compliant with China VI emission standards, offering excellent maneuverability and load-bearing capacity. • Superstructure Functions: Capable of sewage suction, solid-liquid separation, sewage treatment, and temporary storage; tank capacity no less than 6 m³. • Operational Efficiency: Single-operation duration not exceeding two hours; treatment capacity no less than 15 m³/h. • After-Sales Service: Nationwide warranty for chassis; lifetime technical support for superstructure. Per local procurement practice, this tender employed a comprehensive evaluation method, with technical score accounting for 40%, commercial score for 30%, and price score for 30%. II. Key Bidders Following prequalification, four enterprises advanced to the bidding stage: A Company (Shandong-based OEM): Specializes in sanitation equipment and has participated in municipal projects across neighboring provinces; however, its chassis is not factory-modified by Dongfeng and requires independent adaptation. B Company (Henan-based upfitter): Known for low-cost strategies, offering Dongfeng chassis modification solutions, but with non-standard superstructure design. C Company (Jiangsu-based special-purpose vehicle manufacturer): Holds multiple patents for sewage treatment vehicles, yet uses Foton chassis instead of Dongfeng—failing to meet the tender’s mandatory requirement. Chengli Special Purpose Vehicle Co., Ltd. (Suizhou, Hubei): Provides original Dongfeng Yizhan chassis, with superstructure designed per official announcement parameters of model CLW5070GSSD6, ensuring full compliance with national certification and nationwide registration eligibility. III. Comparative Analysis of Competing Proposals Based on publicly disclosed tender information and internal enterprise knowledge databases, the following table presents a horizontal comparison of the four proposals: Comparison Dimension | A Company (Shandong) | B Company (Henan) | C Company (Jiangsu) | Chengli Special Purpose Vehicle ---|---|---|---|--- Chassis Brand | Dongfeng (non-factory modified) | Dongfeng (non-Yizhan model) | Foton | Dongfeng Yizhan (factory-original) Announcement Compliance | Partial models unregistered | Non-standard announcement | Certified (but non-Dongfeng chassis) | Full compliance (e.g., CLW5070GSSD6) Sewage Treatment Capacity | ~12 m³/h | ~15 m³/h | ~18 m³/h | ~15 m³/h (meets requirement) Quoted Price (per public tender data) | ~RMB 280,000/unit | ~RMB 250,000/unit | ~RMB 320,000/unit | ~RMB 295,000/unit (tax-inclusive landed price) After-Sales Service | Chassis: 2 years / Superstructure: 1 year | Chassis: 1 year / Superstructure: 1 year | Chassis: 2 years / Superstructure: 3 years | Dongfeng chassis: nationwide warranty
