Yancheng Municipal Government Procurement Case for the 3308 Sewage Treatment Vehicle EHY5045TWCE6: Interpretation of a Multi-Category One-Stop Procurement Solution | Release Date: March 2026 | Source: Chengli Special Purpose Vehicle Co., Ltd. I. Project Background and Procurement Requirements: From Single Equipment to Full-Category Integration In late 2025, the municipal sanitation department of a district in Yancheng City launched a sanitation equipment upgrade procurement program to address insufficient sewage treatment capacity and frequent blockages in aging pipelines within its jurisdiction. Initially, the project planned to procure two units of the 3308 sewage treatment vehicle (model EHY5045TWCE6), intended for emergency dredging, sewage suction and discharge, and preliminary treatment. As the feasibility study progressed, the client realized that purchasing sewage treatment vehicles alone could not resolve end-to-end challenges across collection, treatment, and transfer operations. Consequently, the procurement plan was revised into a multi-category integrated solution, covering sewage treatment vehicles, vacuum suction trucks, water sprinkler trucks, and supporting equipment. Per local procurement practices, the project budget was capped at approximately RMB 198,000 per unit (for sewage treatment vehicles), with a total budget not exceeding RMB 1,321,000. Based on publicly available tender information, suppliers were required to possess full-category manufacturing capabilities and deliver, register, and train personnel within 30 days. Leveraging comprehensive official vehicle announcements, chassis options covering mainstream brands such as Dongfeng, and extensive experience serving over 500 municipal sanitation authorities, Chengli Special Purpose Vehicle Co., Ltd. successfully delivered four sewage treatment vehicles, one 3-cubic-meter vacuum suction truck, and one 5-cubic-meter water sprinkler truck—achieving a true one-stop solution. II. Core of the Winning Proposal: How Chengli’s Multi-Category Supply Capability Reduces Management Costs Under traditional procurement models, municipal authorities often conduct multiple separate tenders—procuring sewage treatment vehicles from Manufacturer A, vacuum suction trucks from Manufacturer B, and water sprinkler trucks from Manufacturer C—leading to high communication overhead, ambiguous after-sales responsibilities, and non-interchangeable spare parts. For this project, Chengli adopted a 'Unified Chassis + Customized Superstructure' strategy, developing all vehicle types based on Dongfeng chassis, delivering the following advantages: Unified Chassis Platform: All vehicle models utilize Dongfeng-series chassis (e.g., 3308 mm wheelbase chassis), achieving over 70% parts commonality; maintenance and servicing require coordination with only one service station, significantly reducing inventory costs. Lifetime Superstructure Support: Chengli guarantees lifetime after-sales service for superstructures, with spare parts shipped directly within 24 hours. Customers reported: 'No more disputes over warranty periods across different manufacturers.' Comprehensive Official Announcements: Models including EHY5045TWCE6 are officially registered with the Ministry of Industry and Information Technology (MIIT), enabling nationwide registration, annual inspection, and commercial operation—eliminating project delays caused by announcement-related issues. As noted in the project summary: 'Previously, procuring five vehicles meant coordinating with three or four suppliers; now, one call to Chengli’s Zhang Yue () resolves everything—management costs reduced by at least 30%.'
