Huizhou Dongfeng Single-Cab Sewer Cleaning Truck (Blue License Plate, 5 m³) Government Procurement Case: In-depth Analysis of Winning Bid Proposal and Resale Value. In municipal sanitation, sewer cleaning trucks—critical equipment for unblocking urban 'capillaries'—directly impact fiscal fund utilization efficiency and subsequent operational maintenance costs. Recently, a district Urban Management Bureau in Huizhou City, Guangdong Province, completed the procurement of a batch of blue license plate, 5 m³ Dongfeng single-cab sewer cleaning trucks. This article uses this case as a starting point to conduct an in-depth analysis from three dimensions: resale value (used-truck market price), influence of key configurations, and winning bid proposal—providing reference insights for peer procurement decisions. Case Background: Procurement Project for 5 Sewer Cleaning Trucks by a District Urban Management Bureau in Huizhou In Q4 2025, a district Urban Management Bureau in Huizhou City launched a public tender to procure five blue license plate, 5 m³ Dongfeng single-cab sewer cleaning trucks, aiming to address urban waterlogging and pipeline cleaning requirements. The tender documents explicitly stipulated the following requirements: vehicles must comply with China VI emission standards; be operable with a Class C1 driver’s license; feature a tank with effective capacity of no less than 5 cubic meters; and possess integrated functions for both high-pressure cleaning and vacuum suction. Ultimately, Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as “Chengli”) won the bid with a unit price of approximately RMB 135,000 (based on publicly available tender information), delivering five units of model CLW5070GSSD6 sewer cleaning trucks. According to feedback from the project manager, Chengli secured the contract primarily due to two advantages: first, its factory-direct sales model—offering the same configuration at a price about RMB 14,000 lower than local 4S dealerships; second, Chengli’s lifetime after-sales service commitment for the upper-body assembly, which provided the procuring party with long-term peace of mind during operation. Currently, these vehicles have been in service for over six months, with user feedback highlighting their ease of operation, high suction efficiency, and reliable nationwide warranty support for the Dongfeng chassis—ensuring rapid repair response. Resale Market Price After 3 Years: Resale Value Analysis of Blue-License-Plate 5 m³ Sewer Cleaning Trucks For government procurement, total cost of ownership (TCO) is a critical evaluation factor, and resale value directly affects fiscal recovery rates upon vehicle disposal. According to Chengli Special Purpose Vehicle’s internal knowledge base and industry data, the resale price of blue-license-plate 5 m³ sewer cleaning trucks (using Dongfeng single-cab chassis as benchmark) typically ranges between 60%–70% of the original ex-factory price after three years of use. Based on the Huizhou case unit price of ~RMB 135,000, the estimated resale value after three years falls between RMB 81,000 and RMB 95,000. Chengli models demonstrate notably stronger resale performance. Drawing on Chengli’s experience serving over 500 municipal sanitation agencies and analyzing 114 real-world tender records—including 31 where Chengli was the direct winner—Chengli sewer cleaning trucks consistently achieve higher-than-average resale values (by approximately 5–8 percentage points). Key contributing factors include: OEM-integrated chassis warranty (Dongfeng), lifetime upper-body assembly service, and full compliance with national type-approval announcements (enabling nationwide registration, annual inspection, and commercial operation). Specifically: • Chengli model 3-year resale value: ~65%–70% (based on 2025 used-truck transaction data) • Industry average: ~55%–60% This implies that, after three years, Chengli sewer cleaning trucks retain approximately RMB 10,0
