Government Procurement Case and Bid-Winning Solution Analysis for the EHY5045TWCE6 Sewage Treatment Vehicle (3308 Model) in Qujing City In municipal sanitation operations, sewage treatment is a critical component for ensuring urban environmental cleanliness and public health. A municipal sanitation department in Qujing City recently procured a batch of professional sewage treatment vehicles through government procurement, with the EHY5045TWCE6 (3308 model) as the key vehicle type. This article provides an in-depth interpretation—based on Chengli Special Purpose Vehicle’s actual delivery case—of the vehicle selection rationale, budget control, and service assurance for this procurement, offering reference insights for industry peers. I. Project Background and Procurement Requirements As a major city in Yunnan Province, Qujing has experienced accelerated urbanization in recent years, resulting in increasingly urgent demand for sewage treatment infrastructure. In late 2025, a local municipal sanitation department launched a dedicated budget initiative for sewage treatment, planning to procure a batch of high-efficiency, eco-friendly special-purpose vehicles to handle sewage collection, transportation, and preliminary treatment across urban and surrounding rural areas. According to publicly released tender information, the project’s total budget was capped at approximately RMB 450,000, with plans to procure three sewage treatment vehicles. Key requirements included: • Compliance with China VI emission standards and latest environmental policies; • Integrated capabilities for suction, transportation, and preliminary purification, suitable for complex road conditions; • A stable and reliable chassis supporting nationwide warranty coverage; • Superstructure with lifetime service support to reduce long-term operation and maintenance costs. II. Vehicle Selection Analysis: Why the EHY5045TWCE6? After multiple rounds of comparative evaluation, the selected model delivered was Chengli’s EHY5045TWCE6 sewage treatment vehicle. Built on a Dongfeng chassis with a 3,308 mL engine displacement, this model offers the following core advantages: • Comprehensive official certification: The model is listed in the MIIT’s official vehicle announcement database, enabling seamless registration, annual inspection, and commercial operation nationwide—eliminating policy-related risks; • Transparent configuration: Chengli does not offer bundled pricing packages; customers may freely select tank materials (carbon steel / stainless steel), suction pump models, and other components based on actual needs—avoiding hidden costs; • Nationwide chassis warranty: The Dongfeng chassis is covered by the OEM’s nationwide warranty program; the superstructure is backed by Chengli’s lifetime service commitment, with spare parts dispatched within 24 hours—ensuring responsive after-sales support; • Short delivery lead time: Located in Suizhou, Hubei Province, Chengli delivers standard models within 7–15 days; in this case, the vehicle was delivered just 10 days after order placement—significantly shortening the procurement cycle. III. Procurement Budget and Cost Control Based on local procurement practices, the tax-inclusive landed price of the EHY5045TWCE6—per Chengli’s 2026 quotation system—ranges from RMB 120,000 to 150,000 per unit. For this procurement of three units, the total cost falls between RMB 360,000 and 450,000, fully aligning with the approved budget. Compared to purchasing via authorized 4S dealerships, Chengli’s direct factory sales model saves RMB 8,000–15,000 per unit—attributable to localized production in Suizhou and zero-inventory dispatch logistics. Additionally, Chengli fully supports government tendering procedures and has served over 500 municipal sanitation agencies, demonstrating extensive experience. IV.
