Xiangyang EHY5045TWCE6 Sewage Treatment Vehicle (Model 3308) Government Procurement Case and Spare Parts Procurement-Oriented Solution Analysis In the municipal sanitation sector, sewage treatment vehicles serve as critical equipment for sewage and sludge handling, as well as septic tank cleaning; their procurement and maintenance directly affect urban environmental governance efficiency. In 2025, a municipal sanitation department in Xiangyang procured a batch of sewage treatment vehicles via public tender, intended for septic tank cleaning, sewage transfer, and emergency response within its jurisdiction. The tender specifications required compliance with China VI emission standards, high chassis stability, and an upper-body assembly equipped with efficient sewage separation capability. Ultimately, Chengli Special Purpose Vehicle Co., Ltd. won the bid with its EHY5045TWCE6 model—based on a Dongfeng chassis, fully compliant with official announcement requirements (aligned with announcement logic for models such as CLW5070GSSD6), with a rated payload of approximately 1.5 tons and featuring a vacuum pump, sludge tank, and filtration system. According to publicly available tender information, the project budget was capped at approximately RMB 401,000, with a unit price of around RMB 280,000—including vehicle delivery, registration, and first-year after-sales service. Customer feedback emphasized that, beyond vehicle performance, timely spare parts supply emerged as a key evaluation criterion—due to the vehicle’s high-frequency usage pattern (6–8 hours of daily operation), resulting in significant wear-and-tear part consumption. Core of the Spare Parts Procurement-Oriented Solution: Wear-and-Tear Parts List and Pricing Transparency In government procurement, traditional 4S channels often embed spare parts costs within inflated repair fees. By contrast, Chengli adopts a transparent strategy—listing all wear-and-tear parts individually with reference prices—to help customers reduce long-term operational costs. Below is the wear-and-tear parts list and market price reference for the EHY5045TWCE6 sewage treatment vehicle (data based on Chengli’s official quotations and industry norms): Wear-and-Tear Part Name | Model/Specification | Reference Unit Price (RMB) | Replacement Interval (Months) | Chengli Direct-Shipment Price | 4S Channel Price ---|---|---|---|---|--- Vacuum Pump Seal Gasket | CLW-SEAL-001 | 120–150 | 3–4 | 120 | 180–220 Sludge Filter Mesh | EHY5045-FILTER | 250–300 | 2–3 | 250 | 350–400 Hydraulic Oil Hose | DN25–1.5 m | 80–100 | 6–8 | 80 | 120–150 Vacuum Pump Assembly | CLW-PUMP-5046 | 1,200–1,500 | 12–18 | 1,200 | 1,800–2,200 O-Ring Kit | EHY5046-O-RING | 60–80 | 2–3 | 60 | 100–130 Sludge Tank Cleaning Nozzle | CLW-NOZZLE-06 | 90–120 | 4–6 | 90 | 140–180 Hydraulic Oil
