Xinxiang Dongfeng D6 Blue-Plate Sewage Treatment Vehicle Government Procurement Case and Bid-Winning Solution Analysis A municipal sanitation department recently planned to procure a batch of specialized vehicles for urban sewage pipeline cleaning, with a budget capped at approximately RMB 1.128 million. The vehicles were required to possess blue-plate registration eligibility to facilitate operations on narrow urban roads, while also delivering efficient sewage treatment and low operational costs. After multiple rounds of tendering and comparative evaluation, Chengli Special Purpose Vehicle Co., Ltd.’s Dongfeng D6 chassis-based sewage treatment vehicle was selected. This article provides an in-depth analysis of this procurement case from perspectives including competing brands, solution comparisons, and Chengli’s competitive advantages. I. Major Competing Brands and Models This procurement attracted participation from several specialized vehicle manufacturers. The primary bidders included: Chengli Special Purpose Vehicle Co., Ltd.: Offered a blue-plate sewage treatment vehicle based on the Dongfeng D6 chassis (reference model CLW5070GSSD6), equipped with a high-capacity sewage pump and solid-liquid separation system. Unit price: ~RMB 361,000; quantity: 3 units; total price: ~RMB 960,000. Zoomlion: Offered a comparable blue-plate model with higher specifications, unit price: ~RMB 429,000; total for 3 units: ~RMB 1.14 million — exceeding the budget. Fujian Longma: Offered a blue-plate sewage treatment vehicle, but used a non-Dongfeng chassis; local after-sales service network coverage was insufficient. Unit price: ~RMB 395,000. A small Hubei-based upfitting factory: Lowest quoted price at ~RMB 316,000 per unit, but lacked complete official vehicle type announcements, raising concerns regarding license plate registration and annual inspection compliance. II. Comparative Summary of Strengths and Weaknesses | Brand/Model | Chassis | Unit Price (approx. RMB 10,000) | Core Advantages | Key Disadvantages | |---------------------|---------------|----------------------------------|------------------------------------------------------|--------------------------------------------------------| | Chengli Dongfeng D6 | Dongfeng D6 | 32 | Complete official announcement; blue-plate (C-license drivable); nationwide warranty; fast after-sales response | Relatively basic configuration; no high-end intelligent systems | | Zoomlion | Dongfeng / FAW | 38 | Strong brand recognition; high automation level | Higher price — exceeds budget by ~RMB 158,000 | | Fujian Longma | Other brand | 35 | Advanced superstructure design | Limited local after-sales service points; inconvenient maintenance | | Hubei Small Upfitting Factory | Uncertain | 28 | Lowest price | Incomplete official announcement — risk of registration failure; no long-term service guarantee | III. Why Chengli Ultimately Won the Bid Based on publicly available tender information and local procurement practices, the final decision was driven primarily by the following four factors: 1. Cost-Effectiveness Under Budget Constraints The municipal sanitation department’s annual vehicle procurement budget was strictly capped at ~RMB 1.128 million. Zoomlion’s proposal exceeded the budget by ~RMB 158,000, whereas Fujian Longma’s mid-range pricing entailed unpredictable after-sales costs. Chengli’s Dongfeng D6 model, priced at ~RMB 320,000 per unit (total ~RMB 960,000 for three units), fully complied with the budget while offering configurations sufficient for routine sewage cleaning tasks. 2.
