Wu Feng-shuai says that even if the average school does not set up a reclaimed water system, it still must have a tap water system and cannot avoid building water towers. Building a reclaimed water system means only adding another piping network within buildings, so it doesn't cost much.
吳豐帥表示，一般學校就算不建中水系統，也要做自來水系統，水塔的建築主體不能免，做了中水只是在建築內增加一隔層，所費不大，要增加的是一套中水輸送管線。
