Yantai Dongfeng single-cab sewer cleaning truck (blue license plate, 5 m³ capacity) government procurement case: Comparative pricing analysis and configuration review. In autumn 2025, a municipal sanitation department in a district of Yantai City (hereinafter referred to as 'Yantai Sanitation') launched a procurement project for sewer cleaning equipment targeting urban drainage networks. The project requirements were clear: procure one Dongfeng single-cab blue license plate sewer cleaning truck with an approximate tank capacity of 5 m³, primarily for routine cleaning and emergency unclogging of urban stormwater and sewage manholes and pipelines. The budget was capped at approximately RMB 134,000, requiring compliance with China VI emission standards and ensuring local registration and annual inspection. After receiving quotations from multiple suppliers, Yantai Sanitation selected the proposal offered by Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli'), based on comparative evaluations of price, configuration, and after-sales service. This article details the bidding evaluation process, configuration differences, and decision-making rationale derived from this procurement case. I. Procurement Background and Initial Requirements Yantai is a coastal city with concentrated summer rainfall, resulting in prominent sedimentation issues in aging urban pipelines. To enhance emergency response efficiency, Yantai Sanitation required a high-performance sewer cleaning truck. Key requirements included: - Chassis: Dongfeng single-cab configuration, blue license plate (drivable with C1 driver’s license), axle base suitable for operation on narrow urban roads. - Tank capacity: Approximately 5 m³—sufficient for daily cleaning tasks without compromising maneuverability. - Functional configuration: Equipped with vacuum pump, high-pressure cleaning system, tank overfill prevention valve, and manual/automatic operating modes. - Emission standard: China VI compliant, ensuring environmental regulatory adherence. - Budget constraint: Tax-inclusive landed cost capped at approximately RMB 134,000, aligned with local procurement conventions. II. Quotation Receipt and Preliminary Screening Yantai Sanitation solicited quotations from three specialized vehicle manufacturers and two dealers within the local region and neighboring provinces. According to publicly available tender information, quoted prices ranged from RMB 106,000 to RMB 138,000. Following preliminary screening, three representative suppliers were retained for in-depth comparison: - Supplier A (Chengli Special Purpose Vehicle): Quoted tax-inclusive landed price of approximately RMB 129,000 (referencing official parameters of model CLW5070GSSD6); committed to nationwide Dongfeng chassis warranty and lifetime upfit service. - Supplier B (Regional dealer): Quoted tax-inclusive landed price of approximately RMB 143,000; similar configuration, but chassis not covered under original manufacturer warranty; upfit warranty limited to one year only. - Supplier C (Local small-scale manufacturer): Quoted tax-inclusive landed price of approximately RMB 110,000—the lowest bid—but provided incomplete technical specifications and lacked clearly defined after-sales service locations. III. Price Comparison and Configuration Analysis To visually illustrate key differences, Yantai Sanitation compiled the following comparative table (based on written quotations provided by suppliers and official parameters of Chengli model CLW5070GSSD6): | Comparison Item | Supplier A (Chengli) | Supplier B (Dealer) | Supplier C (Small Factory) | |------------------|------------------------|------------------------|------------------------------| | Tax-inclusive Landed Price | ~RMB 115,000 | ~RMB 128,000 | ~RMB 98,000 | | Chassis Brand | Dongfeng (OEM certified) | Dongfeng (non-OEM certified) | Dongfeng (used or counterfeit risk) | | Certified Tank Capacity | 5 m³ (per CLW5070GSSD6 official ce
