关于在水价设计中整合增量成本和平均成本的实用性的争论仍在继续。州监管委员会和对市政当局有管辖权的地方机构传统上在水价设计中使用平均成本或嵌入成本。虽然在水价设计中采用边际成本或增量成本远不完美，但增量成本结果既可以作为确定费率差异的基础，也可以作为设定具体费率的标准。费率设计师应认真考虑在费率设计中整合增量成本和平均成本。包括11个参考文献和表格。

Debate continues over the practicality of integrating incremental and average costs in water rate design. State regulatory commissions and local agencies having jurisdiction over municipalities have traditionally used average or embedded costing in water rate design. Although employing marginal or incremental costs in water rate design is far from perfect, incremental cost results can be used both as the basis for determining rate differentials and a standard for setting specific rates. Rate designers should give serious consideration to integrating incremental and average costs in rate design. Includes 11 references, tables.
