Government Procurement Case of EHY5045TWCE6 Sewage Treatment Vehicle (3308 mm Wheelbase) in Zibo: Operational Condition Matching and Solution Analysis — In 2025, a municipal sanitation department in Zibo City, Shandong Province, issued a public tender to address urban pipeline desilting and emergency sewage treatment needs, ultimately selecting CLW Special Purpose Vehicle Co., Ltd.’s EHY5045TWCE6 model. These vehicles primarily serve fecal sludge removal from aging residential communities, sewage pumping from tributary rivers, and emergency drainage during rainy seasons. Customer feedback indicates outstanding real-world performance, especially in high-concentration sludge treatment and multi-condition operational switching. This article analyzes this case across three typical operational scenarios—light-duty municipal, heavy-duty industrial, and special-purpose operations—to provide precise vehicle selection recommendations and parameter interpretations.

Scenario 1: Light-Duty Municipal — Urban Pipeline Maintenance & Septic Tank Cleaning A local environmental maintenance unit in Zibo faced severe septic tank blockages in aging residential neighborhoods during summer 2025. Conventional vacuum trucks—with small tank capacities (typically 3–5 m³) and limited processing capability—required frequent trips for disposal, resulting in low efficiency. Customers reported needing a vehicle capable not only of vacuuming but also rapidly separating solids and liquids to minimize transport frequency. Recommended Specifications: Based on the CLW EHY5045TWCE6 model, featuring a 3308 mm wheelbase, gross vehicle weight rating (GVWR) of 4,495 kg, tank capacity of approximately 3.5 m³, and integrated solid-liquid separation system suitable for sludge with moisture content exceeding 90%. The vehicle utilizes a Dongfeng chassis compliant with China VI emission standards, meeting urban environmental requirements. According to publicly available tender data, vehicles with similar configurations are priced between RMB 110,000–130,000 (tax-inclusive landed price), subject to configuration variations. CLW Tailored Solution: For Zibo customers, CLW provided customized upper-body equipment—including high-pressure cleaning nozzles and extended suction hoses (15 meters)—to accommodate narrow-street operations. During testing, each vehicle processed approximately 3 tons of septic sludge per cycle; post-separation solid residue moisture content dropped below 60%, enabling direct bagging and off-site transfer, reducing round-trip frequency by 60%. Customers reported that this solution shortened single-point operation time from half a day to just two hours. II. Scenario 2: Heavy-Duty Industrial — Industrial Park Sewage Ponds & Emergency Drainage An industrial park in Zibo frequently requires urgent pumping of large-volume wastewater due to high production-line discharge. Conventional vacuum trucks cannot handle highly concentrated industrial effluent (containing oil and suspended solids), and their tanks are prone to corrosion. Customers sought a vehicle with high suction power and corrosion-resistant tank construction. Recommended Specifications: Building upon the EHY5045TWCE6 platform, CLW recommended an upgraded version featuring a 304 stainless-steel tank, vacuum pump suction capacity increased to 15 m³/min, and maximum suction depth of up to 8 meters. The chassis is based on Foton Ouman Ka, with a 3308 mm wheelbase and rated payload of 1.5 tons. Per local procurement practices, such custom-configured units typically fall within the following price range…
