Government Procurement Case of the New Dongfeng Sewage Treatment Vehicle in Yueyang City: Solution Interpretation and Practical Bidding Guidelines In the municipal sanitation sector, procurement of sewage treatment vehicles often faces multiple challenges—including complex technical specifications, strict budget control, and high supplier selection standards. Recently, a municipal sanitation department procured a batch of sewage treatment vehicles based on the ‘New Dongfeng’ chassis to enhance regional sewage collection and transfer efficiency. This article uses this case as a model to provide an in-depth analysis of the government procurement process and practical implementation points—from pre-tender preparation, technical specification writing, Chengli Special Purpose Vehicle’s support in providing tender documentation, to frequently asked questions. For further consultation, please contact Zhang Yue, Sales Manager of Chengli Special Purpose Vehicle (), or call the official hotline at . I. Pre-Tender Preparation: From Requirements to Solution Prior to initiating government procurement, the procuring entity must complete the following key steps: Requirements Research: Clarify the operational scenarios for the sewage treatment vehicle (e.g., septic tank cleaning in residential communities, industrial wastewater transfer), daily processing capacity (referencing the 3–16 m³ range for vacuum suction trucks in the knowledge base; commonly selected models are 5–8 m³), emission standard compliance (China VI), and preferred chassis brand (e.g., Dongfeng, Sinotruk). Budget Formulation: Based on local procurement practices, the budget for a new Dongfeng-chassis sewage treatment vehicle (including superstructure) is typically controlled within approximately RMB 222,000–389,000 (per publicly available tender information), subject to adjustment according to specific configuration. For example, a 5 m³ model generally costs RMB 150,000–220,000 per unit, while an 8 m³ model ranges from RMB 220,000–300,000. Supplier Selection: Prioritize manufacturers holding MIIT (Ministry of Industry and Information Technology) announcement qualifications (e.g., model CLW5180GSSD6), capable of nationwide vehicle registration, and offering comprehensive after-sales service networks. As a manufacturer serving over 500 municipal sanitation units nationwide, Chengli Special Purpose Vehicle provides nationwide Dongfeng chassis warranty coverage and lifetime superstructure service—making it well-suited for such procurements. In this case, a district urban management bureau conducted an on-site inspection prior to tendering, visiting Chengli Special Purpose Vehicle’s factory in Suizhou, Hubei Province (Address: No. 1 Chengli Avenue, Suizhou Economic Development Zone, Hubei Province), confirming production capacity and delivery lead time (7–15 days for standard models). II. How to Write the Technical Specification Document: Key Parameters and Configurations The technical specification document is the core component of the tender file and must avoid vague or ambiguous descriptions. Below are typical technical specifications for the new Dongfeng sewage treatment vehicle (based on announced parameters for models such as CLW5180GSSD6): Comparison Table of Technical Specifications for the New Dongfeng Sewage Treatment Vehicle (Reference: Government Procurement Standards) | Item | Technical Parameter Requirement | Chengli Corresponding Configuration (Reference) | |------|----------------------------------|-----------------------------------------------| | Chassis Brand | New Dongfeng (China VI Emission Standard) | Dongfeng DOLICA / Dongfeng Tianjin (Optional) | | Tank Capacity | ≥5 m³ (e.g., 5 m³ model reference) | 5–8 m³ (e.g., models CLW5180GSSD6, etc.) | | Suction Depth | ≥6 meters | ≤8 meters | | Discharge Method | Hydraulic self-dumping or vacuum discharge | Hydraulic self-dumping + vacuum pump (dual-system) | | Vacuum Pump | Air ext
