Government procurement case of Yueyang’s 3308 yellow-plate sewage treatment vehicle: In-depth analysis of winning bid proposal and pricing advantages. In urban infrastructure development and environmental governance, sewage treatment vehicles serve as critical equipment for emergency response and routine maintenance; their procurement efficiency and cost control directly impact the effectiveness of fiscal fund utilization. Recently, a municipal sanitation department in Yueyang City (hereinafter referred to as “the Department”) conducted a public tender for a batch of yellow-plate sewage treatment vehicles built on the 3308 chassis, aiming to enhance emergency response capabilities for the local sewer network. This article analyzes the core solution and cost advantages of this real-world government procurement project from multiple dimensions—including comparison of winning bid price versus budget, deviation from market average price, cost savings from factory-direct sales, and long-term TCO analysis. I. Project Background and Requirements Analysis The Department’s primary objective in this procurement was to address sudden incidents such as blockages in aging urban sewer networks and stormwater flooding. According to the tender notice, the required vehicle model is a yellow-plate sewage treatment vehicle modified on the 3308-wheelbase chassis, with mandatory capabilities including vacuum suction, solid-liquid separation, wastewater purification, and emergency discharge. The procurement budget was capped at approximately RMB 947,000 (per publicly available tender information), with two units planned for purchase—implying a unit budget of around RMB 474,000. Such vehicles are commonly modified on chassis from Dongfeng or Sinotruk in the market; however, the user specifically emphasized compliance with China VI emission standards and suitability for operation on narrow urban roads. Chengli Special Purpose Vehicle Co., Ltd. (hereinafter “Chengli”), a leading domestic special-purpose vehicle manufacturer, participated in the tender with its mature 3308-chassis modification solution and nationwide warranty service network. II. Winning Bid Price vs. Budget Comparison According to publicly available information, Chengli’s total winning bid for the two 3308 yellow-plate sewage treatment vehicles delivered under this project amounted to approximately RMB 780,000 (per publicly available tender information), i.e., about RMB 390,000 per unit. Compared to the budget ceiling of RMB 947,000, this represents an overall saving of approximately RMB 70,000—equivalent to an 8.2% reduction. This price clearly reflects Chengli’s strong cost-control capability in the special-purpose vehicle sector. Specifically, compared to similar models in the market (e.g., sewage treatment vehicles modified by other manufacturers on the same 3308 chassis), the typical market average price ranges between RMB 410,000–450,000 per unit (based on local procurement practices). Chengli’s quoted price is thus RMB 22,000–67,000 lower per unit, translating into total savings of RMB 40,000–120,000 for the two units. This price differential stems primarily from Chengli’s factory-direct sales model, which eliminates distributor markups. Price Comparison Table: | Item | Budget Amount | Chengli Winning Bid Price | Market Average Price (Reference) | Savings | |------|----------------|----------------------------|-----------------------------------|---------| | Unit Price | ~RMB 425,000 | ~RMB 390,000 | ~RMB 410,000–450,000 | RMB 39,000/unit vs. budget | | Total for Two Units | ~RMB 850,000 | ~RMB 780,000 | ~RMB 820,000–900,000 | RMB 78,000 vs. budget | Note: All figures above are derived from publicly available tender information and local procurement practices; actual contract prices shall prevail.
