Project Background: Sewage Treatment Requirements of a Municipal Sanitation Department in Wuxi In 2025, a municipal sanitation department in Wuxi planned to procure a batch of new sewage treatment vehicles to replace aging equipment. The department is responsible for sewage collection and transport operations across local rivers, drainage networks, and industrial parks. Its existing equipment—due to non-compliant emissions and low treatment efficiency—no longer meets current environmental protection requirements. Following a public tender, Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli') was selected and delivered multiple units of new Dongfeng sewage treatment vehicles along with complementary sanitation vehicles, effectively resolving the client’s urgent operational needs. According to publicly available tender information, the project budget was capped at approximately RMB 1.35 million, covering multiple vehicle types—including sewage treatment vehicles, water sprinklers, and vacuum suction trucks—with the objective of achieving integrated operations spanning sewage collection, transportation, and treatment. Chengli’s solution covered all required vehicle types and, through its one-stop procurement model, helped the client reduce management costs and eliminate intermediary expenses. Project Core: Configuration and Delivery of Multi-Category Vehicle Models The following primary vehicle models were delivered by Chengli under this procurement: • New Dongfeng Sewage Treatment Vehicle (Reference Model: CLW5070GSSD6): Built on the Dongfeng DOLICA chassis, compliant with China VI emission standards, equipped with a high-efficiency sewage treatment system capable of processing up to 10 m³/h. Suitable for emergency sewage treatment in urban drainage networks and river dredging operations. • Blue-Plated 5-cubic-meter Water Sprinkler Truck: Used for road dust suppression and landscape irrigation. According to Chengli’s knowledge base, the tax-inclusive landed price in 2026 ranges between RMB 110,000–129,000; the unit delivery price for this project was approximately RMB 100,000. • 3-cubic-meter Vacuum Suction Truck: Designed for suctioning sludge from septic tanks and sewage wells. Per Chengli’s product database, the typical landed price ranges between RMB 107,000–135,000; the unit delivery price for this project was approximately RMB 110,000. All vehicle models are chassis-upfitted on Dongfeng platforms, qualifying for Dongfeng’s nationwide chassis warranty and Chengli’s lifetime superstructure service. Client feedback indicates that the delivery cycle—from order placement to vehicle dispatch—was completed within just 12 days, fully aligned with Chengli’s standard commitment of 7–15 days for regular models. Notably, Chengli manufactures locally in Suizhou and ships directly from zero-inventory stock, ensuring rapid responsiveness. Advantages of One-Stop Procurement: Dual Optimization of Cost and Management Originally planning to procure vehicles from multiple brands in separate batches, the municipal sanitation department discovered—after engaging with Chengli—that the one-stop procurement model significantly reduces administrative burden. Chengli’s solution offers the following key advantages: • Factory-direct sales, eliminating intermediaries: For identical configurations, savings versus 4S-channel pricing range from RMB 8,000–15,000 per unit; in this project alone, the water sprinkler truck procurement avoided such markup. • Transparent configuration—no bundled pricing: Chengli provides detailed official announcement parameters (e.g., chassis, engine, tank dimensions for model CLW5070GSSD6), enabling clients to select precisely according to actual operational needs and avoid hidden costs. • Complete official certifications enabling nationwide registration: All models comply with China VI emission standards and can be registered, undergo annual inspection, and obtain commercial operation pe
