Hengyang 3308-Yellow-Plate Sewage Treatment Vehicle Government Procurement Case and Bid-Winning Solution Analysis In 2025, a prefecture-level municipal sanitation department publicly tendered a batch of 3308-mm-wheelbase yellow-plate sewage treatment vehicles for emergency response and routine maintenance of urban and industrial park sewage networks. Tender information indicated a total project budget capped at approximately RMB 907,000, with three units planned for procurement at an estimated unit price of around RMB 260,000. After multiple rounds of technical evaluation and commercial negotiation, Chengli Special Purpose Vehicle Co., Ltd. secured the contract based on its comprehensive official announcement parameters, flexible configuration options, and reliable after-sales service—ultimately delivering three units of the CLW5070GSSD6 model sewage treatment vehicle. This article provides an in-depth analysis of the winning bid case from perspectives including competitor comparison, solution advantages, and key procurement considerations. Major Competing Brands and Models Participating in the Tender According to publicly available tender information, the main brands participating in the bidding included Chengli Special Purpose Vehicle, Hubei Zhongqi, a Shandong-based modification plant, and a local dealer representing a southern Chinese brand. All submitted models were primarily based on 3308-mm-wheelbase yellow-plate chassis equipped with China VI-compliant engines; their upper structures were required to fulfill core functions including sewage suction/discharge, solid-liquid separation, and temporary storage. Chengli’s offered model was the CLW5070GSSD6, fully registered in the MIIT Announcement database, built on a Dongfeng chassis, featuring a stainless-steel tank and equipped with a self-priming sewage pump and preliminary filtration system. Hubei Zhongqi proposed a model based on a Sinotruk chassis, priced slightly higher at approximately RMB 317,000. The Shandong-based modification plant offered a lower-priced option at around RMB 249,000, but used a secondary-tier chassis brand, raising user concerns regarding long-term reliability. The southern brand represented by the local dealer quoted approximately RMB 306,000, yet lacked a direct local service station.
