Government Procurement Case and Bid-Winning Solution Analysis for the New Dongfeng Sewage Treatment Vehicle in Bengbu City — Q3 2025. A municipal sanitation department in Bengbu City, Anhui Province, publicly procured a batch of new Dongfeng sewage treatment vehicles for urban river dredging and emergency treatment of black-and-odor water bodies. Following an open tender process, Chengli Special Purpose Vehicle Co., Ltd. won the bid and delivered three Dongfeng DOLICA chassis-based sewage treatment vehicles, with a total contract value of approximately RMB 1.65 million (per publicly available tender information). Based on this case, this article analyzes the project background, reasons for Chengli’s successful bid, technical highlights of the vehicle model, and provides references for similar projects as well as answers to frequently asked questions. Project Basic Information Procuring Entity: A municipal sanitation department in Bengbu City Procurement Scope: New Dongfeng sewage treatment vehicles (complying with China VI emission standards) Quantity: 3 units Budget: Maximum budget capped at RMB 1.879 million (per publicly available tender information) Winning Bidder: Chengli Special Purpose Vehicle Co., Ltd. Winning Bid Amount: Approx. RMB 550,000 per unit (per local procurement practice) Delivery Timeline: Delivery to be completed within 20 days after contract signing Chassis Model: Dongfeng DOLICA D7 Series This project is primarily intended for handling low-concentration sewage and sludge mixtures from urban drainage networks and rivers. The vehicles must feature rapid suction, solid-liquid separation, sewage purification, and remote discharge capabilities. Per the procurement documents, the vehicles must support continuous operation for over 8 hours, and the treated effluent must meet Grade III requirements stipulated in the 'Comprehensive Wastewater Discharge Standard'. Analysis of Reasons for Chengli’s Successful Bid Chengli Special Purpose Vehicle Co., Ltd. secured the bid primarily due to the following three core advantages: 1. Comprehensive Official Announcements and Nationwide Compliance for Registration All Chengli sewage treatment vehicle models (e.g., CLW5070GSSD6) are officially listed in the MIIT (Ministry of Industry and Information Technology) announcement database, with full China VI emission certification and environmental information disclosure. This ensures smooth registration, annual inspection, and commercial operation licensing at local traffic management offices in Bengbu—eliminating delivery delays caused by missing official announcements. According to the knowledge base entry 'MIIT Announcement Parameters (108 entries)', Chengli has accumulated mature and extensive official announcement resources for sewage treatment vehicles—a critical competitive advantage in government procurement. 2. Direct Factory Sales, Transparent Configuration, and Controllable Costs As a manufacturer, Chengli participated directly in the bidding process, eliminating intermediary distribution channels. Compared to 4S dealership channels, same-specification models typically offer cost savings of RMB 9,110–17,100. In this project, Chengli’s bid clearly itemized costs for chassis, upper structure, sewage treatment system, piping accessories, etc., avoiding bundled pricing—fully meeting the tenderer’s requirements for transparency and compliance. 3. Comprehensive After-Sales Service Support Chengli guarantees nationwide joint warranty coverage for Dongfeng chassis and lifelong service for the upper structure. For municipal sanitation departments, rapid response to equipment failures is critical. Chengli maintains service centers across Anhui Province and neighboring regions; spare parts are shipped directly within 24 hours. Moreover, Chengli already has established cooperation cases in Bengbu (e.g., previously delivered water-sprinkling trucks and street-sweeping vehicles), receiving consistently positive customer feedback.
