6.4.1) Water reuse policy

The university sets annual water conservation goals, including zero growth in water usage or reducing water consumption by 1% as the annual water conservation target. These targets are reviewed periodically through meetings of the Environmental Sustainability Promotion Committee at the end of each year to assess the effectiveness of water usage.

In terms of rainwater reuse, due to the long history of the university, older buildings are generally not equipped with water recycling devices. Therefore, the school stipulates that new and renovated buildings should follow relevant water resources indicators of the national green building standard and set up water recycling equipment accordingly. New buildings such as the Lecture Building at the Lanyang Campus and the Hsu Shou-Chlien International Conference Center at the Tamsui Campus are equipped with rainwater storage tanks following the requirements of the Green Building Standards.

In terms of wastewater treatment, our school has been engaging in relevant research and have achieved fruitful results, including the project of "Total Recycling and Cleaning Process of Ceramic Filter Membrane for Waste Incineration Recycling Production Wastewater" and the patent of "Fluorinated Wastewater Treatment System" to improve wastewater recycling technology, as well as to enhance the efficiency of wastewater treatment.

Starting from 2021, the school not only increased the number of rainwater recycling equipment (rain harvesting) but also coordinated with the sewage treatment plant, relying on self-employed water trucks to carry reclaimed water from the sewage treatment plant for campus sprinkler irrigation, floor cleaning, and toilet flushing use, continuously increase the campus water reuse rate, while reducing the cost of sewage treatment.
