Project Background: Sewage treatment requirements of a sanitation department in a district of Fuyang City. In 2025, a municipal sanitation department in Fuyang City, facing increased demands for pipeline unclogging and sewage treatment within its jurisdiction, planned to procure one 3308 yellow-plate sewage treatment vehicle. The vehicle must feature high-suction capability, high-pressure cleaning, sewage separation, and emergency drainage functions—intended for routine pipeline maintenance and post-rainwater flood mitigation. According to publicly released tender information, the project budget was capped at approximately RMB 398,000, requiring compliance with China VI emission standards, a chassis covered by nationwide warranty, and lifetime after-sales service for the superstructure. After comprehensive evaluation and comparison, the department ultimately selected Chengli Special Purpose Vehicle Co., Ltd.’s 3308 yellow-plate sewage treatment vehicle. As one of China’s largest special-purpose vehicle manufacturers, Chengli maintains 946 product specifications across 44 categories, with complete official announcements for sewage treatment vehicles—including models such as CLW5070GSSD6, all featuring full technical parameters. The department procured two units at a unit price of approximately RMB 320,000 each, replacing aging equipment. These vehicles are now operational, and customer feedback highlights their ease of operation and high processing efficiency. Standard Version vs. Premium Version: Detailed Functional Comparison For the 3308 yellow-plate sewage treatment vehicle, Chengli offers two configuration options: Standard and Premium. The Standard version suits customers with limited budgets and light-duty daily operations; the Premium version enhances intelligence and processing capacity, making it ideal for high-intensity, multi-scenario applications. Below is the detailed comparison: Configuration Item | Standard Version | Premium Version ---|---|--- Chassis Model | Dongfeng 3308 (China VI) | Dongfeng 3308 (China VI) Engine Power | Approx. 115 HP | Approx. 130 HP Sewage Tank Capacity | Approx. 8 m³ | Approx. 10 m³ Suction Pump | Vacuum Pump (Suction Lift: 8 m) | Rotary Vane Pump (Suction Lift: 10 m) High-Pressure Cleaning System | Standard 15-m high-pressure hose, pressure: 150 bar | Standard 20-m high-pressure hose, pressure: 180 bar Sewage Treatment Method | Simple sedimentation + discharge | Multi-stage filtration + water recycling Control System | Manual valve control | PLC-based automatic control system Onboard Accessories | Standard suction hose, spare tire | Suction hose + cleaning gun + emergency lighting Reference Price (Tax-Inclusive, Delivered) | Approx. RMB 280,000 | Approx. RMB 350,000 As shown in the table, the Standard version suits customers with a budget around RMB 319,000, whereas the Premium version fits those with budgets up to RMB 398,000 who require robust performance for complex pipeline networks. In the Fuyang case, the department opted for the Premium version due to aging infrastructure and frequent blockages in its pipeline network—the multi-stage filtration system significantly reduces subsequent maintenance costs. Value Analysis of Optional Equipment: Key Enhancers of Operational Efficiency Beyond the Standard and Premium versions, Chengli offers a range of optional accessories enabling customers to customize vehicles according to actual needs. Below are the key optional accessories considered by the client in this case, along with their value analysis: Automatic Hose Reel (Optional price: approx. RMB 3,410): Enables automatic retraction and deployment of the high-pressure cleaning hose, reducing manual labor time. In the Fuyang case, the client reported saving approximately 30 minutes per day on hose handling—cumulatively saving about 180 hours annually. Sewage Water Recycling System (Optional price: approx. RMB 17,000): Recycles treated clean water for reuse, minimizing external di
