Selected into CWA Typical Engineering Project Case Database! BEWG Sets Industry Benchmark with Hard-Core Technology 2026-01-21
Recently, Yinchuan No.1 Reclaimed Water Plant (hereinafter referred to as "Yinchuan No.1"), invested, constructed and operated by BEWG Group, was selected into the "2025 China Urban Water Supply and Drainage Association Typical Engineering Project Case Database" for its comprehensive performance in "innovation, advancement, economy, and intelligence", becoming one of the eight benchmark engineering projects awarded nationwide.
Yinchuan No.1 is the largest semi-underground garden-style wastewater treatment plant in Northwest China, with a total investment of 1.5 billion yuan and a designed treatment capacity of 300,000 tons/day. The project closely aligns with the national strategy of ecological protection and high-quality development in the Yellow River Basin, creating a demonstration project that transforms the "not-in-my-backyard (NIMBY) effect" into a "neighbor-benefit effect" through green and low-carbon operation, smart management, and public participation mechanisms, supporting Yinchuan City in building a national water-saving city and a benchmark for an ecologically livable city in Northwest China.
Technology Empowerment: Setting a Benchmark for Smart Operation and Energy Efficiency
Yinchuan No.1 adopts a self-optimized combined process of "multi-stage feed modified Bardenpho process" and "Actiflo high-density sedimentation technology", improving nitrogen and phosphorus removal efficiency by 20% compared to traditional processes, reducing footprint by 40%, with effluent quality stably meeting Class IV surface water standards, and sludge resource utilization technology selected as a national green technology innovation case.
Through semi-underground intensive design, Yinchuan No.1 achieves a 40% improvement in land utilization, with energy consumption per ton of water at no more than 0.035 kg of standard coal, more than 20% below the industry average. The smart water system enables precise process control, reducing chemical dosing costs by 18%, saving 2.9 million kWh of electricity annually, and significantly improving operational efficiency.
Pursuit of Excellence: Building Benchmark Quality and Winning Honors
From design to construction, Yinchuan No.1 adhered to the principles of high standards and high quality throughout, implementing lean management and refined construction to achieve high-standard delivery.
The project has successively won important national, provincial and municipal awards, including "First Prize of Beijing Excellent Engineering Survey and Design Achievement Evaluation", "Second Prize of Engineering Construction Science and Technology Progress Award", "Highest Quality Level Evaluation Project of Municipal Engineering", "Xixia Cup Quality Engineering Award of Ningxia Hui Autonomous Region", "Gold Award of Smart Construction Cup China Smart Construction Application Competition", "Gold Award of the 15th Yuanye Cup Professional Award", and "Outstanding Award in Flood and Water Management Category of IFLA APR AAPME AWARDS".
Ecological Sharing: Building Urban Green Space and Science Education Base
Underground pollution treatment, aboveground greening. The above-ground space of Yinchuan No.1 has been developed into a 19-hectare ecological park, featuring sports fields, children's playgrounds, and wetland landscapes, becoming a popular leisure destination for citizens. The supporting environmental education exhibition hall and Party building corridor have received over 4,000 visitors, winning the national "Water-Saving China, You and I Together" outstanding activity title, becoming an important regional environmental protection science education base.
From "NIMBY" to "neighbor-benefit", Yinchuan No.1 Reclaimed Water Plant has delivered a high-quality water governance answer through technological innovation and ecological practice. BEWG upholds the development philosophy of "lucid waters and lush mountains are invaluable assets", using benchmark projects as a driving force to create water service models integrating ecological governance, people's livelihood services, and science education for more cities, writing a new chapter of water governance and urban development in the new era.
