Because of their production processes (which include the use of acids as cleansers), high-tech industries are major water users, and for them conserving water lowers costs. Therefore, these factories happily buy into conservation campaigns. For example, newer semiconductor plants in the Hsinchu Science-Based Industrial Park recycle about 95 % of their water, whereas the older ones recycle about 60-70 %.
整體而言，高科技業因為有酸液清洗等製程，屬於高耗水產業，節水可以降低成本，所以廠商都樂意配合，例如新竹科學園區半導體產業，做得好的廠商廢水回收率達 95 %。
