I. Procurement Background and Requirements Analysis In 2025, a municipal sanitation department in the Deyang area planned to procure a batch of National VI emission-standard wastewater treatment vehicles to enhance urban wastewater treatment capacity. In line with local procurement practices, the budget was controlled at approximately RMB 507,000. Preliminary research confirmed the buyer’s explicit requirement for a Dongfeng chassis with a 3308 mm wheelbase—optimized for Deyang’s complex road conditions and narrow alleyways. These vehicles will primarily serve emergency suction, drainage, and preliminary treatment operations in old residential communities, farmers’ markets, and combined sewer systems. This procurement attracted participation from multiple enterprises, including CLW Special Purpose Vehicles. Ultimately, CLW secured the contract based on its comprehensive solution. Post-delivery feedback from the client indicated stable vehicle operation and effective mitigation of localized flooding and odor issues. Below is a breakdown—by core tender evaluation criteria—of how CLW’s solution precisely met procurement requirements. II. Tender Evaluation Criteria Breakdown: Scoring Logic (Total: 100 Points) Per local government procurement practice, the evaluation system typically comprises Technical Score (40 points), Commercial Score (30 points), Price Score (20 points), and Service Score (10 points). This analysis focuses on the three core components—Technical, Commercial, and Service—to illustrate how CLW precisely aligned with requirements. | Evaluation Dimension | Points | Key Requirements | CLW’s Response Strategy | |----------------------|--------|------------------|--------------------------| | Technical Score | 40 | Announcement parameters, emission standard, treatment capacity, chassis compatibility | Provided models such as CLW5070GSSD6; National VI emission compliance; Dongfeng chassis with 3308 mm wheelbase | | Commercial Score | 30 | Corporate qualifications, supply capability, performance references, contract terms | Demonstrated 500+ municipal cooperation cases (e.g., Henan Sanitation Bureau, Wuhan Urban Management Bureau) | | Price Score | 20 | Lowest bid receives highest score—but must not fall below cost price | Factory-direct pricing: RMB 8,000–15,000 lower than 4S-channel equivalents for identical configurations; quoted range: approx. RMB 485,000–530,000 | | Service Score | 10 | Warranty period, response time, spare parts availability, training program | Nationwide chassis warranty; lifetime upfitting service; spare parts shipped within 24 hours | III. Maximizing the Technical Score: From Tender Announcement to Actual Vehicle Configuration The Technical Score carries significant weight in government procurement. CLW’s National VI-compliant wastewater treatment vehicle—based on the Dongfeng 3308 mm wheelbase chassis—carries the official model designation CLW5070GSSD6 (referencing MIIT announcement parameters). This model holds full MIIT certification, ensuring nationwide registration eligibility, annual inspection compliance, and operational licensing. 3.1 Chassis and Emission Compliance The vehicle utilizes the Dongfeng 3308 mm wheelbase chassis—featuring a short wheelbase and small turning radius—ideal for narrow streets in Deyang’s historic urban districts. It is powered by a National VI diesel engine, satisfying the strictest current emission standards and fulfilling the buyer’s explicit ‘green and environmentally friendly’ requirement. 3.2 Wastewater Treatment Capacity Equipped with a high-power vacuum pump and filtration system, the vehicle can suction approximately 3–4 m³ of wastewater per operation and perform preliminary solid-liquid separation. Compared to peer-level models, its treatment efficiency improves by ~15%, and it includes a high-pressure cleaning system to remove pipeline residue. As part of standard procurement practice, the buyer conducted an on-site inspection at CLW’s Suizhou ma
