NCKU’s water reuse measurement

Decentralized Flood Mitigation and Eco-Ponds
In response to the ecological shortcomings of conventional urban rapid drainage systems, a research report by the Architecture and Building Research Institute, Ministry of the Interior, advocates for decentralized "eco-ponds" and on-site water retention technologies. This approach aims to achieve "soft flood mitigation" by managing floodwaters at their source, with the ultimate goal of establishing localized design standards to support formal legislation.

Campus Implementation of Sustainable Water Management
Our university actively implements this sustainable water management philosophy. We have established a comprehensive water reuse measurement system, featuring a "Rainwater Harvesting System" with integrated monitoring. This system systematically collects water from rooftops, swimming pool overflows, and other sources. After treatment, this reclaimed water is consistently used to replenish campus eco-ponds (such as Cheng-Kung Lake), irrigate landscapes, and flush toilets, significantly reducing our reliance on municipal tap water.

Performance Monitoring and Public Transparency
To ensure effectiveness and transparency, we regularly compile and publish performance data. From 2022 to 2024, the system total reclaimed and reused 36,746 tons of water, with all related data publicly available on our official website. Our initiative not only demonstrates efficient campus water management but also serves as a successful case study of implementing national-level soft flood mitigation research.
  1. NCKU’s Rainwater Retention System
A “rainwater storage system” and monitoring equipment have been established to systematically collect water from rooftops, swimming pool overflow, and other sources. After treatment, the recycled water is reliably used to supplement on-campus ecological ponds (such as Chenggong Lake), irrigate vegetation, and supply toilet flushing, significantly reducing tap water consumption.



 
  1. Collaboration between wastewater and microbial communities holds promise for wastewater treatment plants to move toward a carbon-neutral era
NCKU’s research team combines Comammox and Anammox bacteria to optimize nitrogen removal from low-concentration municipal wastewater, converting ammonia into stable nitrogen gas. This approach reduces aeration energy use and carbon emissions, improving reclaimed water treatment efficiency and environmental safety, and showcasing NCKU’s leadership in energy-saving, carbon reduction, and carbon-neutral water treatment.
 
  1. Turning Wastewater into High-Tech Water: NCKU and Tainan City Advance Sustainable Resources
The Department of Environmental Engineering at NCKU, in collaboration with the Tainan City Government, ASUS, and Shuangjian Smart Company, is advancing the "Yongkang Water Resource Recovery Center 5G Smart Management Demonstration Project," converting wastewater into high-tech water. NCKU leads AIoT, smart sentinel monitoring, and data integration, enhancing water quality monitoring accuracy and system analysis, showcasing innovative achievements in smart water resource management and sustainable water reuse through industry-government-academia collaboration.
