Government Procurement Case and Bid-Winning Solution Analysis for the Dongfeng D6 Blue License Plate Sewage Treatment Vehicle in Fuyang In the context of municipal sanitation infrastructure upgrades, sewage treatment vehicles—key equipment for environmental protection initiatives—have seen continuously rising procurement demand in recent years. In 2025, a municipal sanitation department in Fuyang City, Anhui Province (hereinafter referred to as 'a certain Fuyang unit') conducted an open tender to procure a batch of Dongfeng D6 blue license plate sewage treatment vehicles for urban sewer network cleaning and emergency response. This article provides an in-depth analysis of the procurement background, solution highlights, residual value performance, and key configuration impacts of this case, based on publicly available tender information and Chengli Special Purpose Vehicle’s product database, offering reference for similar procurement projects. I. Case Background: Why Did the Fuyang Unit Choose the Dongfeng D6 Blue License Plate Sewage Treatment Vehicle? As a major city in northern Anhui, Fuyang has experienced rapid urban expansion in recent years, resulting in prominent demands for upgrading aging sewer networks. In Q2 2025, the unit launched its sewage treatment vehicle procurement plan, specifying requirements including: blue license plate (drivable with Class C driver’s license), 3–4 m³ sewage tank, Dongfeng chassis, China VI emission standard, simple operation, and low maintenance costs. After multiple rounds of comparative evaluation, the unit ultimately selected Chengli’s Dongfeng D6 blue license plate sewage treatment vehicle (model CLW5070GSSD6, chassis-modified). According to the tender documents, the budget cap was approximately RMB 169,000 per unit; referencing local procurement practices, the final winning bid price was around RMB 142,000 per unit. Chengli Special Purpose Vehicle delivered five units for this project. Customer feedback indicated outstanding maneuverability in narrow urban alleys and low failure rates for the upper-structure components (i.e., the sewage treatment system). Mr. Zhang Yue, Chengli Sales Manager (Tel: ), noted that this model is built on the Dongfeng D6 chassis, powered by a Quanchai 130-horsepower engine, compliant with China VI emission standards, fully certified, and eligible for nationwide registration, annual inspection, and commercial operation. II. Solution Analysis: Why Did Chengli’s Dongfeng D6 Blue License Plate Sewage Treatment Vehicle Win the Bid? Three suppliers advanced to the evaluation stage for this procurement. Chengli’s proposal stood out due to the following advantages: Chassis Reliability: The Dongfeng D6 chassis enjoys high market penetration in the municipal sanitation sector, supported by over 1,500 authorized service centers nationwide, ensuring ready access to repair services and spare parts. According to Chengli’s internal knowledge base, Dongfeng chassis account for more than 40% of Chengli’s sanitation vehicle shipments. Modular Upper-Structure Design: The sewage tank is fabricated from 4-mm-thick stainless steel for superior corrosion resistance; equipped with a self-priming pump (60 m³/h flow rate) and high-pressure cleaning system, capable of handling sediment buildup in urban sewer networks. Chengli offers lifetime after-sales support, with upper-structure components shipped directly within 24 hours. Zero-Inventory Delivery: Chengli’s Suizhou factory delivers standard models within 7–15 days; this order was fulfilled in just 10 days—from contract signing to vehicle pickup—meeting the Fuyang unit’s urgent requirement for deployment before the rainy season. Outstanding Cost-Effectiveness: As a direct manufacturer, Chengli eliminates intermediaries, saving RMB 8,000–15,000 compared to 4S-channel pricing for identical configurations. The landed price of this model in Fuyang is approximately RMB 160,000—about RMB 12,000 lower than compar
