目标计费系统是旨在鼓励节水的节水附加费和折扣率系统。每个住宅和商业账户都有一个基于内部和外部用水的既定节水目标。附加费公式是基于用水目标的用水百分比乘以消费收入。目标计费系统的目标是到2000年每年节约3000英亩英尺的水。

The goal billing system is a water conservation surcharge and discount rate system that is designed to encourage water conservation. Each residential and commercial account has an established water conservation goal based on inside and outside water use. The surcharge formula is based on the water use percentage over the water use goal multiplied by the consumption revenue. The objective of the goal billing system is to conserve 3,000 acre feet of water annually by the year 2000.
