冲洗的基本机理已经有了很好的定义，但对于如何评估或优化冲洗方案的有效性知之甚少。在本文调查的公用事业公司中，超过一半的公司都有冲洗程序，并利用客户投诉来查找配电系统中的问题。通过根据投诉数据刷新优先级，使用电子表格对配送系统内的区域进行排序。每一个区域都可能因预计到投诉高峰而被冲洗。制定了总体规划方法或方案，以协助项目组织和分析。其中包括对费城郊区自来水公司进行的冲洗项目的审查。包括11个参考文献、表格和图表。

The fundamental mechanics of flushing are well defined, but little has been known about how to evaluate or optimize the effectiveness of flushing programs. More than half the utilities surveyed for this article have flushing programs and use customer complaints to locate problems in the distribution system. A spreadsheet was used to order areas within a distribution system by flushing priority on the basis of complaint data. Each area could be flushed in anticipation of the peak of complaints. A general planning method or protocol was developed to assist with program organization and analysis. A review of a flushing program conducted by the Philadelphia Suburban Water Company is included. Includes 11 references, tables, figure.
