因2015年全台面臨嚴重旱象,珍惜水資源與水價調整議題再次浮現,同時也引發全台水價是否統一問題進行討論。本文以台灣自來水公司12個區管理處為探討對象,進行分析結果,因各區管理處淨水處理成本不同,第一、五、七~十一區等7個區管理處,即平均每銷售一度水之營業利益為負之區管理處,其單位售價應進行調漲,而其他第二、三、四、六、十二區等五個區管理處,即平均每銷售一度水之營業利益為正之區管理處,其單位售價應進行調降,可讓台水公司在不同水價訂定下逹到損益兩平。 因此,水價應分區制定較為合理,才能避免賺錢之區管理處補貼不賺錢之區管理處,並消除用水小戶補胋用水大戶不符合社會公平正義之現象。
Because of Taiwan in facing the serious drought in 2015, issues of both cherish water resources and fee pricing adjustment come up again. In the meanwhile, it also give rise to debate whether to unify fee pricing throughout Taiwan. In this paper, the objective of this study was to analyze the impact of water rate adjustments among the 12 branches of Taiwan Water Corporation. In view of the fact that the water treatment costs are different among different branches. Selling price per unit will go up when average per unit water sell yielding negative operating income in these seven branches including the First, the Fifth, and from the Seventh to the Eleventh branches. In contrast, the other branches average per unit water sold generating positive operating income, then selling price per unit should be decreased. As such, Taiwan Water Corporation can set different rates to reach its operating breakeven point. Therefore, the more reasonable water rates in different branches can be prevented by those branches making profits to subsidize the others branches running in losses. In doing so, it can promote social fairness and justice in terminating the policy of higher water users to be subsidized by lower water use customers.
