Government Procurement Case and Bid-Winning Solution Analysis for the Dongfeng Yizhan-Style Sewage Treatment Vehicle in Wuhan In the municipal sanitation sector, sewage treatment vehicles serve as critical equipment for handling emergency sewage spills, pipeline dredging, and environmental emergency response—driving sustained growth in procurement demand. In 2024, a district Urban Management Bureau in Wuhan publicly tendered for a batch of Dongfeng Yizhan-style sewage treatment vehicles, with a total budget capped at approximately RMB 1.341 million for four units. This case not only reflects the government’s high requirements for equipment professionalism and regulatory compliance but also exemplifies typical industry qualification review and solution-matching processes. This article uses this case as a starting point to provide an in-depth interpretation of essential qualifications required for legitimate manufacturers, verification methods, and how Chengli Special Purpose Vehicle Co., Ltd. distinguished itself through technical strength in similar projects. I. Procurement Background and Project Overview A municipal sanitation department in Wuhan required four Dongfeng Yizhan-style sewage treatment vehicles due to expansion of local wastewater treatment stations and urgent repair needs. The vehicles were required to be built on Dongfeng chassis (meeting China VI emission standards), feature a wing-type body design for convenient equipment operation, and deliver a minimum treatment capacity of over 30 m³/hour. The total project budget was approximately RMB 1.341 million (per publicly disclosed tender information), translating to roughly RMB 300,000 per unit. Following open tendering, qualification review, technical evaluation, and commercial negotiations, Chengli Special Purpose Vehicle Co., Ltd. was awarded the contract and delivered the vehicles. It is understood that the client had previously procured 5-cubic-meter street sweepers and water-sprinkling trucks from Chengli (refer to Chengli’s case library: 15 street sweepers for Wuhan Urban Management Bureau). They provided positive feedback regarding Chengli’s superstructure manufacturing quality and after-sales service. For this procurement, the client placed particular emphasis on regulatory compliance, core component specifications, and emergency response capability. II. Qualification Review: Essential Certifications for Legitimate Manufacturers and Verification Methods In government procurement, qualification review serves as the first step to ensure suppliers are legally registered, compliant, and capable of delivering high-quality performance. Below is a checklist of mandatory certifications for sewage treatment vehicle procurement, along with verification pathways: 1. Essential Certifications for Legitimate Manufacturers • MIIT Announcement of Vehicle Manufacturers and Products: Vehicle models must be listed in the “Announcement of Road Motor Vehicle Manufacturers and Products.” For example, Chengli models such as CLW5070GSSD6 are included in the official announcement. Verification can be performed via the MIIT official website or dedicated special-purpose vehicle announcement query platforms. • CCC Compulsory Certification Certificate: Vehicles must obtain CCC certification issued by the China Certification and Accreditation Administration (CNCA), confirming compliance with national safety and environmental protection standards. • ISO Quality Management System Certification: e.g., ISO 9001, demonstrating standardized production management practices. • Environmental Information Disclosure: China VI-compliant models must be registered on the Ministry of Ecology and Environment’s Motor Vehicle Environmental Information Disclosure Platform. • After-Sales Service Commitment Letter: Clearly specifying nationwide chassis warranty (e.g., Dongfeng chassis) and lifetime superstructure service. • Tendering/Bidding Case Evidence: Submission of contracts or award notices fro
