Government Procurement Case and Winning Bid Solution Analysis for the 3308 Yellow-Plate Sewage Treatment Vehicle in Bengbu City In the second quarter of 2025, a municipal sanitation department in Bengbu City issued a procurement notice for five units of 3308 yellow-plate sewage treatment vehicles, intended for emergency urban sewer network maintenance and riverbed dredging operations. Per local procurement conventions, the budget was set at approximately RMB 388,000 per unit, with requirements including China VI emission compliance, full official vehicle announcements (e.g., model CLW5070GSSD6), and delivery within 15 days. Leveraging its extensive announcement database (covering 946 product entries) and proven track record of successful bids—including 15 street-sweeping vehicles for Wuhan Urban Management Bureau and 10 water-sprinkling vehicles for a Henan sanitation office—Chengli Special Purpose Vehicle Co., Ltd. secured the contract with a bid price of approximately RMB 338,000 per unit, totaling around RMB 1.69 million. This procurement placed particular emphasis on engine adaptability, as Bengbu lies in the Jianghuai Plain; however, certain operational zones involve the Huai River embankment and mild hilly terrain, while also requiring resilience against summer heatwaves and winter cold. Consequently, engine power selection directly impacts both operational efficiency and fuel economy. I.
