6.5.4) Sustainable water extraction on campus
Utilise sustainable water extraction technologies on associated university grounds off campus.

The Tamsui Campus of TKU piloted a self-employed water truck to carry recycled water from the Tamsui wastewater treatment plant for use as an auxiliary sprinkler irrigation system for planting and planting on campus. Facing the uneven drought and flood in Taiwan caused by global climate change, teaching faculties from the Department of Water Resources and Environmental Engineering of TKU and National Taiwan University jointly developed a sustainable management strategy for groundwater resources. People's livelihood and industrial water demand and the environment, the environmental impact caused by groundwater development was reduced. In addition, the research topics of teaching faculties have also extended to the reuse of recycled water, from early biological treatment, membrane treatment, electrodialysis water regeneration, to the research and development of innovative membranes, and to assist the continuous improvement of Taiwan's wastewater treatment industry recycling technology. For instance, the use of nanofiber filter membranes with composite layer charges, so that low-voltage operation can be used for water treatment and filtration, and the filter membrane materials can be customized. It can effectively remove sodium, calcium, and magnesium plasma from the water, saving 30% to 50% of the wastewater treatment cost.
