Taiwan's water resource policy in the past was need driven and was a response to the needs of economic growth. If there was a certain water deficit, then that's the amount of new water resources that would be developed. Now, however, we take into account the fact that resources have limits and so their use should also have limits.
台灣過去的水資源政策是「供給導向」，因應經濟成長需求，缺多少水就開發多少，現在則考量到資源有限，必須有所限制。
