为水系统的资本改善提供资金的一种方法是，根据用户对峰值需求的贡献，根据用户分类设置费率结构。出于非必要的自由支配目的用水的住宅用户按倾斜的定额收费，而使用属于感知基本需求类别的住宅用户则按定额收费。工业和商业用户按递减区块收费。包括桌子。

One method of providing funds for capital improvements to water systems is to set rate structures according to user classifications based on their contribution to peak demand. Residential users who use water for discretionary, nonessential purposes are charged by inclining block rates, while residential customers whose use falls within perceived essential need categories are charged a block rate. Industrial and commercial users are charged on a declining block basis. Includes tables.
