Government Procurement Case and Bid-Winning Solution Analysis for the CN6 Dongfeng Sewage Treatment Vehicle with 3308 mm Wheelbase in Hengyang In Q3 2025, a municipal sanitation department in a district of Hengyang urgently needed to procure a batch of high-performance sewage treatment vehicles after a sudden blockage occurred in the drainage network of an aging industrial zone within its jurisdiction, resulting in mixed backflow of domestic and industrial wastewater. The unit had previously not deployed such specialized equipment and faced both tight budgetary constraints and urgent timelines—requiring full deployment, from tender issuance to vehicle operation on-site, within 15 working days. Based on this real-world government procurement case, this article outlines the complete process—from emergency requirement identification to CLW’s rapid delivery—to serve as a reference for similar emergency procurements. I. Background of the Emergency Requirement: Why Purchase a Sewage Treatment Vehicle? The area’s drainage system was constructed in the 1990s. With accelerated industrialization, severe pipe sedimentation has occurred; compounded by consecutive heavy rainfall events in recent years, this has led to sewage overflow and odor-related public complaints. Conventional vacuum trucks can only remove solid sediments and are ineffective against high-concentration wastewater or oil-water mixtures. On-site inspection confirmed the need for a sewage treatment vehicle featuring integrated functions—including suction, separation, filtration, and discharge—with CN6 emission compliance. The chassis wheelbase had to suit narrow local streets (3308 mm being the optimal choice), and continuous operation capability of over 8 hours was mandatory. According to the unit’s publicly released procurement requirements (referenced from the local government procurement website), the total budget was capped at approximately RMB 506,000, with plans to procure two units—i.e., ~RMB 253,000 per unit. Key technical specifications included: - Chassis model: Dongfeng EQ1075SJ3CDF (3308 mm wheelbase, CN6-compliant); - Superstructure functions: Wastewater suction (suction depth ≥ 8 m), solid-liquid separation (treatment capacity ≥ 30 m³/h), and either reclaimed water reuse or discharge meeting regulatory standards; - Additional requirements: Fully automated operation, self-diagnostic fault detection, and 24-hour after-sales response. II. Expedited Tender Process: From Announcement to Bid Opening in Just 7 Days Given the urgency, the unit adopted an “emergency procurement” procedure, streamlining standard tender processes. Key milestones were as follows: - Day 1: Issued the “Emergency Procurement Notice” on the government procurement platform, specifying vehicle quantity, technical parameters, and delivery deadline (15 working days); - Day 3: Received responses from four suppliers, including CLW Special Purpose Vehicle Co., Ltd. (“CLW”); - Day 5: Conducted expert evaluation focusing on supplier qualifications, product announcements (e.g., MIIT-certified models such as CLW5070GSSD6), after-sales service capability, and pricing; - Day 7: Announced CLW as the winning bidder. According to feedback from participating experts, CLW secured the award based on advantages including factory-direct sales, zero-inventory shipment, and comprehensive official vehicle certifications. Notably, CLW’s submitted proposal—featuring a Dongfeng chassis paired with a CLW superstructure—had full vehicle certification documentation and transparent, itemized pricing with no hidden costs. It is worth highlighting that CLW explicitly committed in its tender documents to: “Nationwide Dongfeng chassis warranty; lifetime superstructure service; and 24-hour direct dispatch of spare parts”—a pledge that directly alleviated the procuring party’s concerns regarding long-term maintenance.
