Government Procurement Case and Bid-Winning Solution Interpretation for the New Dongfeng Sewage Treatment Vehicle in Yibin City Project Background and Core Tender Document Requirements In early 2026, the Urban Management Bureau of a district in Yibin City, Sichuan Province, issued a public tender notice for sewage treatment vehicles, aiming to enhance emergency sewage treatment capacity within its jurisdiction. The project budget was capped at approximately RMB 1.335 million, with plans to procure two units of the new Dongfeng sewage treatment vehicles (per publicly available tender information). Core tender requirements were as follows: Chassis: Must use Dongfeng-branded, China VI emission-standard chassis; newer models preferred, with excellent maneuverability and stability. Superstructure Performance: Sewage tank capacity must be no less than 5 m³; equipped with high-power vacuum pump; treatment capacity must reach over 30 m³/hour; automatic unloading function required. MIIT Announcement & Registration: Vehicles must be listed in the MIIT’s official vehicle announcement database to ensure nationwide registration, annual inspection, and commercial operation eligibility. After-Sales Service: Chassis must be covered under Dongfeng’s nationwide joint warranty program; superstructure warranty period must be no less than two years; supplier must guarantee technical support response within 24 hours. Delivery Timeline: Full delivery must be completed within 20 days after contract signing. The tender document further stipulated that bidders must submit documented evidence of at least three similar projects completed within the past three years, along with official MIIT announcement parameter sheets for the proposed vehicles. Chengli Special-Purpose Vehicle Technical Response Proposal As one of China’s largest special-purpose vehicle manufacturers, Chengli Special-Purpose Vehicle Co., Ltd. (“Chengli”) promptly formed a dedicated bidding team and developed a comprehensive technical response proposal aligned precisely with the tender requirements. Chassis Selection: Selected the new Dongfeng China VI chassis (model reference: CLW5070GSSD6 per MIIT announcement parameters), featuring a proven, high-torque, fuel-efficient engine—fully meeting operational demands on mountainous roads in Yibin. Superstructure Configuration: High-strength carbon steel tank with 5 m³ capacity; equipped with a Germany-imported vacuum pump, achieving an actual measured treatment rate of 35 m³/hour—exceeding the tender requirement by 10%. Additionally integrated an automatic liquid-level control system and anti-spill overflow protection device to significantly enhance operational safety. MIIT Announcement Compliance: The CLW5070GSSD6 model supplied by Chengli is already officially listed in the MIIT’s vehicle announcement database—no additional application required—ensuring seamless registration procedures. Proven Project Experience: Chengli has delivered multiple units across Sichuan Province—for example, four high-pressure cleaning and suction sewage trucks to a municipal authority in Sichuan (refer to knowledge base case records), receiving consistent feedback praising vehicle reliability and ease of maintenance. Commercial Quotation Strategy and Bid Submission In the commercial quotation phase, Chengli adopted a “direct factory sales, no intermediaries” pricing strategy. Based on the 2026 reference landed price from the knowledge base, a 5 m³ blue-plate sewage treatment vehicle (similar configuration) typically costs RMB 98,000–115,000 per unit. However, this tender specified yellow-plate vehicles (requiring larger tanks and higher compliance standards); thus, Chengli’s quotation was: Unit Vehicle Price: Approximately RMB 161,000 (including chassis, superstructure, and MIIT announcement-related fees, per local procurement practice). Total Bid Price: Approximately RMB 323,000 (for two units), representing ~20% below the budget ceiling—highligh
