越来越多的水务公司正在使用以节约为导向的水价结构来帮助促进高效用水。统一费率、季节费率、反向阻塞费率和超额使用费率用于提供价格信号，以促进节水，尤其是在居民用水者中。这些费率结构已成功地用于传递适当的定价信号，并帮助支持更广泛的保护工作。本文将介绍几种使用节能技术的水系统- 有针对性的费率结构，并审查水资源使用随时间的变化。为正在考虑实施其中一种费率结构的水务公司提供了策略和建议。包括7个参考文献、表格、图表。

Increasing numbers of water utilities are using conservation-oriented water rate structures to help promote efficient water use. Uniform rates, seasonal rates, inverted-block rates, and excess-use rates are used to provide pricing signals that promote water conservation, particularly among residential water users. These rate structures have been used successfully both to convey appropriate pricing signals and to help support broader conservation efforts. This article looks at several water systems that use conservation-oriented rate structures and reviews changes in water use over time. Strategies and suggestions are offered for water utilities that are considering implementing one of these rate structures. Includes 7 references, tables, figures.
