Driver's Perspective on the Jinan 3308 Sewage Treatment Vehicle EHY5045TWCE6: Government Procurement Case Study and Real-World User Feedback. In municipal sanitation, sewage treatment vehicles are critical equipment for ensuring smooth urban drainage systems and responding to sudden pollution incidents. A municipal sanitation department in Jinan recently procured six Chengli Special Purpose Vehicle Co., Ltd.-manufactured 3308 sewage treatment vehicles (model: EHY5045TWCE6) through public tender, for emergency response and routine maintenance of local rivers, sewage pipelines, and industrial parks. This article analyzes the vehicle’s operational convenience, ease of operation for C-license drivers, common precautions, and FAQs — all from the perspective of actual drivers — providing reference for procurement entities. Case Background: Procurement Decision by Jinan Municipal Sanitation Department According to publicly available tender information, a municipal sanitation department in Jinan launched its sewage treatment vehicle procurement project in 2025, with a budget capped at approximately RMB 337,000. After multiple rounds of evaluation, Chengli Special Purpose Vehicle Co., Ltd.’s EHY5045TWCE6 model was selected. Built on Dongfeng’s 3,308 mm wheelbase chassis, the vehicle is equipped with a China VI-compliant engine and features Chengli’s proprietary vacuum suction and solid-liquid separation system, along with a 3-cubic-meter sewage tank. Customer feedback cited the following key reasons for selecting Chengli: direct factory sales eliminating intermediaries, resulting in cost savings of RMB 8,000–15,000 compared to 4S-channel alternatives; nationwide Dongfeng chassis warranty coverage; lifetime after-sales service for the superstructure; and 24-hour direct shipment of spare parts. Additionally, the vehicle carries complete official announcements, enabling normal registration, annual inspection, and commercial operation nationwide. Driver’s Perspective: Real-World Usage Experience and Operational Convenience Mr. Li (a pseudonym), a driver employed by the Jinan sanitation department, has operated this vehicle for over three months, handling daily sewage collection and transportation tasks. He shared: “Driving this vehicle feels similar to operating an ordinary light-duty truck, but with more concentrated functionality. The power-assisted steering makes turning effortless; clutch travel is well-tuned; gear shifting is smooth. Most conveniently, the superstructure control panel is located right beside the driver’s cabin—allowing vacuum pump and discharge valve operations without stepping out of the cab.” Specifically, the EHY5045TWCE6 demonstrates exceptional operational convenience through: - One-Touch Suction/Discharge: Via the in-cabin LCD display, operators can monitor tank liquid level and vacuum pressure in real time, and initiate or halt suction/discharge operations with a single button—eliminating cumbersome manual procedures. - Low-Noise Design: Both the engine and vacuum pump are fitted with sound-dampening enclosures, keeping operational noise below 65 dB(A) to minimize disturbance to residential areas. - Safety Features: Standard equipment includes rear-view camera, dashcam, and rollover prevention system—providing clear visibility during reversing and reducing accident risk. C-License Ease-of-Use: Can Novice Drivers Operate It Effortlessly? The vehicle’s gross vehicle weight rating (GVWR) is 4,495 kg, fully compliant with China’s Blue-Plate C-license driving requirements. Mr. Li commented: “I previously drove a pickup truck under my C1 license—and adapted to this vehicle on day one. Its short wheelbase (3,308 mm) and small turning radius make maneuvering in narrow streets or residential compounds highly agile. Superstructure operation training took only half an hour; the main challenge was memorizing the sequence of a few control buttons.” According to Chengli’s official FAQ knowledge base, the EHY5045TWCE6’s d
