2019 National Chung Cheng University Social Responsibility and Sustainability Report Section 7.1.4 page 117-118 highlights the following event as Clear Water and Sanitation to achieve the SDGs. 1. Build a rainwater r ecycling system to collect rainwater and use it for irrigation and flushing water after appropriate treatment. 2. Purchase non-frequency conversion air-conditioning and require an energy-saving controller (the lowest temperature is 26℃, automatic power-off in 3 hours). 3. Establish a campus electricity and water resources monitoring system to effectively grasp the real-time water and electricity situation and records of the whole school. Furthermore, the addition of pipeline flowmeters in the campus water pipeline network area can speed up the judgment of water leakage and shorten the repairing time.
