The water supply on campus is mainly tap water treated by the public water purification plant. No water use is involved with water extraction from rivers, lakes, and groundwater.
◆The three campuses of the university are all located in areas with abundant rainfall all year round. With the rainy nature of the region as a focus point, the school has been actively developing methods of collecting and reusing rainwater in recent years. The collected rainwater is then used for plants irrigating within the campus, which not only helps to reduce the burden of relying on purchased tap water but also takes into consideration the responsibility of environmental protection. In addition, the school employs water trucks to carry recycled water from the sewage treatment plant, which then acts as a water source for sprinkler irrigation on campus. In addition to reducing the burden of relying on purchased tap water, it is also responsible in terms of environmental protection.
◆Facing the uneven phenomenon of drought and flood in Taiwan caused by global climate change, teachers from the Department of Water Resources and Environmental Engineering and National Taiwan University jointly developed a sustainable management strategy for groundwater water resources, with the needs of people's livelihood being taken heavily into consideration, as well as industrial water use, the environment, and reducing the environmental impact caused by groundwater development.
◆In addition, the research topics of our teachers have also expanded to the reuse of recycled water, from the early biological treatment, membrane treatment, and electrodialysis water regeneration, to the research and development of innovative filter membranes, assisting the continuous improvement of recycling technology in our country's wastewater treatment industry. For example, the use of nanofiber membrane, with the charge of the composite layer, can be used for water treatment and filtration at low voltage, and the membrane material can be customized and adjusted to effectively remove sodium, calcium, magnesium, and other ions from water, saving wastewater treatment costs by three to fifty percent.
◆Assistant Professor Sheng-Wei Wang from the Department of Water Resources and Environmental Engineering executed a research project funded by the National Science and Technology Council titled "The Impact of Agricultural Irrigation Pumping on Groundwater and Adaptation Strategies During Drought Periods."
