单费率结构、下降费率结构和倾斜费率结构对水消耗的影响预测取决于消费者需求与水成本之间的不同假设。三个关键的假设，在此基础上，以前的研究速度结构和水资源保护进行了审查。在考虑替代费率结构时，必须考虑收入要求、相对使用率以及高使用率组和低使用率组之间的价格弹性。包括3个参考文献、表格和图表。

Projections of the influence of single rate structures, declining rate structures, and inclining rate structures on water consumption depend on varying assumptions about how consumer demand will relate to the cost of water. Three crucial assumptions upon which a previous study of rate structures and water conservation was based are examined. Revenue requirements, relative use rates, and price elasticities between high- and low-use groups must be taken into account when alternative rate structures are considered. Includes 3 references, tables, figure.
