6.4.1) Water reuse policy

As old buildings generally do not have water recovery devices, the water recovery equipment is mainly designed to match new buildings, such as the Lanyang Campus Teaching Building and Hsu Shou-Chlien International Conference Center. Rainwater reservoirs are set up for these new buildings, and the collected rainwater is used as sprinkler irrigation for plants. The three campuses set water-saving goals each year, including setting zero growth in water use or reducing water consumption by 1% as the annual water-saving goal. These goals are regularly review for the effectiveness of water use through environmental sustainability promotion committee meetings at the end of each year. As the sewage pipe is included in the construction of New Taipei City, the Tamsui campus pays an additional sewage treatment fee every month. Charges are calculated based on the tons of water used (influent) per month. Thus, the plan is to cooperate with the university's water treatment technology research center to develop campus water recycling and reuse programs and continue to increase the rate of campus water reuse. After the water is recycled, it can be used for campus sprinkler irrigation, floor cleaning of buildings, or toilet flushing, which can reduce the amount of tap water and the expenditure on on-campus water and electricity.
