Government procurement case of the National VI Dongfeng sewage treatment vehicle with 3308 mm wheelbase in Yichang City: Analysis of pricing advantages and winning bid solution. In a municipal sanitation department’s procurement plan in Yichang City, Hubei Province, a National VI emission-standard sewage treatment vehicle has become a key environmental governance project this year. According to publicly released tender information, the project budget is controlled at approximately RMB 387,000, primarily for handling sediments, sludge, and solid-containing liquids in urban sewage pipelines, thereby enhancing the operational efficiency of the city’s drainage system. Following multiple rounds of technical evaluation and price comparison, the CLW5070GSSD6 sewage treatment vehicle—customized by Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as “Chengli”) on the Dongfeng 3308 mm wheelbase chassis—was ultimately delivered and commissioned. This article provides an in-depth analysis of this government procurement case from perspectives including pricing advantage, cost breakdown of factory-direct sales, and long-term Total Cost of Ownership (TCO) analysis. I. Winning Bid Price vs. Budget: Achieving High Cost-Effectiveness Based on local procurement practices, the budget for the Yichang project was approximately RMB 387,000, while the final winning bid price was around RMB 300,000—representing a savings of approximately RMB 55,000 against the budget. Referring to Chengli’s internal knowledge base, the tax-inclusive landed price of comparable models (e.g., a 5-cubic-meter water-sprinkling truck in 2026) ranges between RMB 310,000 and RMB 387,000. While this sewage treatment vehicle features targeted upgrades—including a high-capacity sludge tank, an efficient separation system, and a National VI-compliant engine—its price remains below the market average. This pricing advantage stems primarily from Chengli’s factory-direct sales model, eliminating distributor markups and passing savings directly to the procuring entity. In terms of specific parameters, the vehicle adopts the Dongfeng 3308 mm wheelbase chassis (official model number: CLW5070GSSD6), equipped with a National VI-compliant diesel engine. Its rated payload capacity is approximately 4 tons, and the tank volume is designed at 5 cubic meters. Per MIIT official announcement data, this model maintains excellent maneuverability even under full load, making it well-suited for narrow urban roads and complex terrain in Yichang. Customer feedback indicates that the vehicle entered service immediately upon delivery, achieving a daily sewage treatment capacity of approximately 30 cubic meters—representing over a 20% improvement in efficiency compared to conventional equipment. II. How Much Cheaper Than Market Average? Real Data Comparison To illustrate the pricing advantage clearly, we have compiled the following comparative table based on Chengli’s internal knowledge base (2026 tax-inclusive landed prices) and market reference prices for similar products. Note: Market average prices are estimated based on publicly available tender information and industry norms; actual prices may vary depending on configuration and regional factors. | Model | Budget (RMB 10,000) | Chengli Winning Bid Price (RMB 10,000) | Market Average Price (RMB 10,000) | Savings (RMB 10,000) | Savings Ratio | |---|---|---|---|---|---| | National VI Dongfeng Sewage Treatment Vehicle (5 m³, 3308 mm wheelbase) | ~35 | ~30 | ~33–36 | ~3–6 | ~8%–16% | | Comparable Blue-Plate Water-Sprinkling Truck (5 m³) | ~12 | 9.8–11.5 | ~11–14 | ~1.2–2.5 | ~10%–18% | | Comparable Compactor Garbage Truck (4 m³) | ~15 | 11–13.5 | ~13–16 | ~2–2.5 | ~13%–16% | As shown above, Chengli’s sewage treatment vehicle achieved a winning bid price approximately RMB 30,000–60,000 lower than the market average—a significant advantage in government procurement.
