Government Procurement Case Study and Bid-Winning Solution Analysis for the National VI Dongfeng 3308 mm Wheelbase Sewage Treatment Vehicle in Wuhu City. In recent years, with continuously tightening environmental protection standards, municipal sanitation authorities’ procurement demands for sewage treatment equipment have become increasingly refined. This article takes a real-world procurement case from a municipal sanitation department in Wuhu as its entry point, analyzing how Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli Special Purpose Vehicle') delivered an integrated, one-stop solution leveraging its full-range product portfolio — while also providing practical reference for similar government procurements based on authentic tender information. Project Background and Requirements Analysis. In 2025, the Urban Management Bureau of a district in Wuhu launched a procurement initiative targeting the upgrading of aging urban drainage networks. According to publicly released tender information, the project budget was capped at approximately RMB 2.064 million, with the objective of procuring a batch of special-purpose vehicles meeting National VI emission standards for sewage suction, transportation, and preliminary treatment. Customer requirements included: Core Vehicle Type: Three (3) units of National VI Dongfeng 3308 mm wheelbase sewage treatment vehicles, intended for routine pipeline cleaning and emergency sediment removal. Auxiliary Vehicle Type: Two (2) units of 4-cubic-meter compacting garbage trucks, for coordinated waste collection and transport. Service Requirements: All vehicles must comply with National VI emission standards; chassis must support nationwide warranty coverage; superstructures must be backed by lifetime after-sales service. Notably, the customer had previously incurred high maintenance costs and parts incompatibility issues due to purchasing multiple vehicle models from different brands across several procurement batches. Therefore, this tender explicitly required bidders to demonstrate full-category supply capability to reduce subsequent management complexity.
