Ganzhou Municipal Level VI Dongfeng 3308 mm Wheelbase Sewage Treatment Vehicle Government Procurement Case and Bid-Winning Solution Analysis Against the backdrop of increasingly stringent environmental regulations, municipal sanitation departments’ demand for sewage treatment equipment continues to rise. However, first-time procurement often falls into pitfalls such as 'low-price bait bidding', 'opaque configuration', and 'inadequate after-sales support'. This article analyzes a real-world case of a second procurement by a municipal sanitation department in Ganzhou, interpreting how to avoid these pitfalls, and provides a detailed overview of the Level VI Dongfeng 3308 mm wheelbase sewage treatment vehicle solution and quotation—offering scientific reference for procurement personnel. I. Pitfalls Encountered During the First Procurement: Lessons Learned by a Ganzhou Municipal Sanitation Department In 2024, the Urban Management Bureau of a district in Ganzhou procured three sewage treatment vehicles to address mounting urban sewage treatment pressure. The budget was capped at approximately RMB 1.352 million (about RMB 400,000 per unit, based on publicly available tender information). However, serious issues emerged during actual operation: • Opaque Configuration: The winning bidder provided only a generic description—'National VI chassis + sewage pump'—without specifying critical parameters such as tank material, pump model, or filtration system. Upon delivery, it was discovered that the tank wall thickness was less than 3 mm; corrosion appeared within six months. • Slow After-Sales Response: When vehicles malfunctioned, repair technicians had to travel from out-of-town, requiring three days—disrupting daily operations. • Mismatch Between Superstructure and Chassis: The superstructure-mounted sewage pump was incompatible with the Dongfeng chassis power take-off (PTO), causing unstable rotational speed and reducing treatment efficiency by 30%. This experience taught the procurement team: 'Low price does not equal low total cost—transparent configuration and localized service are paramount.' II. Avoiding Pitfalls in the Second Procurement: Scientific Vehicle Selection and Tender Strategy In 2025, the department launched its second procurement round, with a budget capped at approximately RMB 1.689 million (based on local procurement norms), planning to acquire two sewage treatment vehicles at roughly RMB 750,000 each. This procurement strictly adhered to the following principles: 1. Clearly Defined Technical Specifications—No Vague Descriptions The tender document explicitly required: a Dongfeng 3308 mm wheelbase National VI emission-compliant chassis; a tank fabricated from Q345B high-strength steel (minimum thickness ≥ 4 mm); a high-capacity sewage pump (flow rate ≥ 120 m³/h); and an automatic filtration and separation system. Suppliers were also required to provide official MIIT-registered model numbers (e.g., Chengli CLW series) as proof of qualification. 2. Emphasis on After-Sales Service Suppliers were mandated to offer nationwide Dongfeng chassis factory warranty coverage, lifetime superstructure service, and guaranteed 24-hour direct shipment of spare parts. This requirement effectively disqualified small, non-local modification workshops. 3. On-Site Manufacturer Evaluation The procurement team conducted an on-site inspection of Chengli Automobile Industrial Park in Suizhou, Hubei Province, confirming the company’s capability for zero-inventory delivery (standard models delivered within 7–15 days) and its extensive experience serving over 500 municipal sanitation units. III. A Mature Buyer’s Vehicle Selection Logic: In-Depth Analysis of the Level VI Dongfeng 3308 mm Wheelbase Sewage Treatment Vehicle Solution After comprehensive evaluation, the department selected the CLW-series Level VI Dongfeng 3308 mm wheelbase sewage treatment vehicle supplied by Chengli Special Purpose Vehicle Co., Ltd.
