Based on projections of population and industrial development trends, by the year 2006 Taipei City will not be in a position to provide water to Taipei and Taoyuan Counties, and Taipei County only has the short Sanhsia River which can still be dammed. But this is just a drop in an empty bucket, and not even enough to supply emergency needs.
依人口、產業推估，台北市到民國九十年將無力再支援台北縣、桃園用水，台北縣也只剩短短的三峽河可以攔水，但杯水車薪，救急、救窮都不足。
