Tangshan EHY5045TWCE6 Sewage Treatment Vehicle (3308 mm Wheelbase) Government Procurement Case: A Practical Guide to Avoiding Pitfalls in Secondary Procurement and a Mature Solution In the municipal sanitation sector, procurement of sewage treatment vehicles is rarely a one-off transaction. Many agencies only realize 'you get what you pay for' after operational issues surface with their first unit. A municipal sanitation department in Tangshan, Hebei Province, encountered such pitfalls during its initial procurement—and subsequently switched to Chengli Special Purpose Vehicles for its second purchase, selecting the EHY5045TWCE6 model, achieving compliant deployment and efficient operation. This article analyzes the case—from lessons learned from the first procurement, to how risks were mitigated in the second, to mature buyers’ vehicle selection logic—and concludes with an FAQ section, aiming to provide reference for procurement entities nationwide. I. Pitfalls Encountered in the First Procurement: A Lesson in 'Low Price' In 2024, the Urban Management Bureau of a district in Tangshan planned to procure a compact sewage treatment vehicle to address small-scale wastewater treatment station operations and pipeline desilting needs within its jurisdiction. With a budget capped at approximately RMB 226,000, and following local procurement conventions, it selected a chassis-based vehicle from a certain brand priced at around RMB 169,000. However, upon delivery, multiple issues emerged: - Chassis–Body Mismatch: Insufficient chassis load capacity caused severe vehicle vibration during upper-structure equipment operation, significantly impairing work efficiency. - Announcement Compliance Issues: The vehicle model was not fully registered in the MIIT (Ministry of Industry and Information Technology) Announcement, rendering normal registration at the local traffic management bureau impossible—and subsequent annual inspections problematic. - Inadequate After-Sales Support: The chassis and upper structure were supplied by separate manufacturers; when failures occurred, responsibility was shirked between parties, and spare parts delivery took up to one month. - Poor Operational Performance: Although nominal sewage treatment capacity met specifications, actual throughput reached only 60% of design capacity, and effluent quality failed to meet discharge standards—resulting in official warnings from environmental protection authorities. Key Takeaway: Procuring specialized sanitation vehicles cannot hinge solely on price. Chassis announcement compliance, upper-structure compatibility, after-sales service capability, and real-world operational performance are all indispensable. After six months of frequent breakdowns and irreparable faults, the vehicle was decommissioned—resulting in direct fiscal waste. II. How the Second Procurement Avoided These Pitfalls: Shifting from 'Low Price' to 'Comprehensive Cost-Effectiveness' In 2025, the department launched a new procurement initiative, raising its budget moderately to approximately RMB 339,000. Learning from prior experience, the procurement team established clear requirements: - Chassis Requirements: Must be based on a mainstream-brand chassis, fully listed in the MIIT Announcement, and support nationwide registration and annual inspection. - Upper-Structure Performance: Sewage treatment capacity must satisfy actual operational demands, backed by third-party test reports. - After-Sales Service: Manufacturer must provide nationwide chassis warranty coverage and lifetime upper-structure service. - Tender Compliance: The product model must be fully included in the MIIT Announcement, with clearly identifiable announcement number. After multiple rounds of supplier evaluation and comparative pricing, the department ultimately selected the EHY5045TWCE6 sewage treatment vehicle offered by Chengli Special Purpose Vehicles. This model is built on a 3308 mm wheelbase chassis and classified as a comp
