由于水需求的增长或下降、水质变化、基础设施老化等原因，配水系统正在不断变化。对配水系统的评估必须基于一系列长期分析的措施。在本文中，配电系统性能的评估表示为系统客户所接受的服务水平。所有水系统应使用本研究中制定的性能标准和性能参数评估其配水系统的性能。结构性能、水力性能和水质性能等参数性能缺陷的解决方案是相互关联的。建议所有供水系统每年对配水系统进行全面评估。

Water distribution systems are changing continuously as a result of growth or decline of water demand, changes in water quality, aging infrastructure, etc. An assessment of the distribution system must be based upon a set of measures analyzed over an extended period of time. In this paper, the assessment of distribution system performance is expressed in terms of the level of service received by customers of the system. All water systems should assess the performance of their distribution systems using the performance criteria and performance parameters developed in this study. Solutions to performance deficiencies of parameters such as structural performance, hydraulic performance and water quality performance are interlinked. It is recommended that all water systems should conduct such a comprehensive assessment of the distribution system annually.
