Analysis of the Government Procurement Case and Winning Bid Solution for the Weihai 3308 Yellow-Plate Sewage Treatment Vehicle. In municipal sanitation sectors, procurement of sewage treatment vehicles often arises from urgent needs to upgrade outdated equipment with insufficient performance. This article details the entire process—from identifying equipment pain points and conducting requirement research to final implementation—using a recent procurement case by a municipal sanitation department in Weihai as an example. Special emphasis is placed on the winning bid solution featuring CLW Special Purpose Vehicle’s 3308 yellow-plate sewage treatment vehicle, offering reference for similar procurements. I. Pain Points of Outdated Equipment: Low Efficiency and High Maintenance Costs The municipal sanitation department in Weihai had previously used a sewage treatment vehicle for over eight years, primarily handling urban pipeline and septic tank wastewater. However, with increasing urban wastewater discharge volumes in recent years, the equipment has increasingly revealed three core issues: Insufficient Treatment Capacity: The original vehicle’s hourly wastewater treatment capacity was only about 15 m³; during peak periods, auxiliary vehicles had to be deployed, resulting in low operational efficiency. Rising Maintenance Costs: Frequent failures of the aging hydraulic system and pump assembly led to annual maintenance expenses exceeding the budget by over 20%, while long spare parts delivery lead times disrupted normal operations. Non-Compliant Environmental Emissions: The original vehicle met only China III emission standards, failing to satisfy Weihai’s current environmental requirements—restricting operations in certain areas. These issues directly prompted the department to launch a new procurement initiative targeting yellow-plate sewage treatment vehicles capable of higher processing volumes and stricter emission compliance. II. New Requirement Research Process: Clarifying Technical Specifications and Budget Prior to formal tendering, the department conducted a two-month preliminary research phase, focusing on the following key dimensions: Treatment Capacity: Minimum required hourly wastewater treatment capacity of ≥30 m³ to accommodate peak operational demands. Chassis & Emission Standard: Must be a yellow-plate vehicle compliant with China VI emission standards; chassis must support nationwide warranty coverage. Superstructure Configuration: Must include a high-efficiency solid-liquid separation system, self-priming pump, and automated control system. Budget Control: Based on local procurement practices, the unit price (including tax and all-in delivery cost) was capped at approximately RMB 450,000. During the research, the department consulted CLW Special Purpose Vehicle’s technical knowledge base and found that models such as the CLW5070GSSD6 were widely applied among peer equipment—with complete official announcements enabling nationwide registration and annual inspection. Following initial contact, CLW Sales Manager Zhang Yue (Tel: +86 ) provided a detailed configuration proposal and quotation. III.
