This project performed Water resource in sustainable use of Chiayi city: Reclaimed water recycle and reuse diagnostic assistance program. Program period started at 5th May, 2010 and ends in 31th Dec, 2010. Summary of performance is as followings: 1. Collection of water resource and evaluation of recycling potential: Collecting all elementary schools and junior high schools in Chiayi city, there are 11 schools (from 20 elementary schools and 8 junior high schools) would build reclaimed water recycle system. By our further interviewed, Chiayi junior high school、Xingchia and Kungping elementary schools have better recycling potential in our evaluation. 2. Planning of reclaimed water recycle system design: Due to Kungping elementary school, we planned to recycle rainwater 418m3 and washbasin water 2600m3 for bio bond refill and irrigation water per year. For Chiayi junior high school, we plan to recycle 5543m3 rainwater for irrigation water per year. And for Xingchia elementary school, we plan to recycle 2000m3 kitchen water for irrigation water、bio bond refill or water pool refill. 3. Building demonstration site: Kungping elementary school was chosen for demonstration site. Because its wind power system、solar power storage system、wind water supply and bio bond are near to our reclaimed water recycle system, we hold demonstration site may not only promotion reclaimed water recycle system, but also have environmental education demonstration effects. According to the agreement from mid-term review, we choose Kungping elementary school to be our demonstration site running build operations. All evaluation and test run has been completed at 30th Nov. 4. Holding advocacy briefings and results demonstration: Our group had held one advocacy briefings for our plan and at 30th Jun.
