Project Background: Urgent Need for Sewer Cleaning and Upgrading in Anshan City’s Drainage System In 2025, the Anshan Municipal Engineering Management Office (Liaoning Province) launched the “Urban Drainage System Cleaning and Emergency Support Project” to address severe aging and sediment accumulation in the city’s sewer network. The project’s core requirement was the procurement of a batch of high-efficiency, highly maneuverable, and fully compliant sewer cleaning vehicles for routine pipeline maintenance and emergency flood control during the rainy season. Following extensive research and a competitive tender process, Anshan City selected Chengli Special Purpose Vehicle Co., Ltd.’s Dongfeng Dual-Cab Sewer Cleaning Truck (Blue License Plate, 3-cubic-meter capacity) as its primary equipment. With a total project budget of approximately RMB 1.989 million, Chengli won the bid directly, delivering 12 units at a total contract value of around RMB 1.5 million—achieving roughly 15% cost savings compared to similar market offerings. Key Project Requirements: - **Urgency**: Severe blockages in aging drainage pipes across certain old urban districts pose a high risk of flooding during heavy rainfall, necessitating rapid deployment of additional cleaning equipment. - **Regulatory Compliance**: All vehicles must meet China VI emission standards and be eligible for local registration, annual inspection, and commercial operation in Anshan. - **Maneuverability**: Vehicles must be compact enough for narrow urban streets and residential areas; driver licensing must align with Class C (C1) requirements, with blue license plates strongly preferred. - **Cost Control**: Given constrained government budgets, procurement costs must be optimized without compromising quality or performance. Chengli Special Purpose Vehicle stood out among numerous bidders by leveraging its key competitive advantages: “factory-direct sales (no intermediaries),” “comprehensive official vehicle announcements enabling nationwide registration,” and “original chassis warranty plus lifetime upfit service.” According to the project lead from Anshan Municipal Engineering Management Office: “Chengli’s Dongfeng dual-cab sewer cleaning truck offers full price transparency—and a delivery cycle of just 12 days—perfectly meeting our urgent operational needs.” Solution: Detailed Configuration of Chengli’s Dongfeng Dual-Cab Sewer Cleaning Truck (Blue License Plate, 3 m³) To precisely meet Anshan’s requirements, Chengli delivered a customized Dongfeng dual-cab sewer cleaning truck solution.
