社区供水系统面临改善性能的压力 因为越来越多的公众监督，越来越少的金融机构 健康和增加基础设施修复/更换 成本。这种压力要求社区供水系统得到改善 与利益相关者绩效各方面相关的责任。 然而，目前的绩效评估和评估 （PAE）社区供水系统的方法是高度个性化的 而且它几乎没有提供基准测试的机会 社区供水系统（CWS）部门的比较。 现有的PAE框架侧重于持续改进 CWS内部的核心流程，不提供 在一个地理区域内对不同服务进行一致的比较。 本文中的研究假设 解决这个问题的办法是:（1）提高公众意识 通过开发标准效率度量（SEM）参数 标准化PAE，使利益相关者能够比较 其CWS的表现符合区域基准；（2） 增强 通过使区域管理层能够 基于统一性能信息的资源分配决策 关于区域水系统中的服务；（3）增加 服务运营效率高于目前的做法。 本文中描述的SEM参数能够 向单个社区提供评估信息 水系统供应商，以提高性能。扫描电镜 参数还可以对 CWSs通过标准化的 PAE框架。作为CWS行业的问责制 通过使用SEM参数，提高了预期的 结果将是更有效的跨部门资源分配决策 作为区域系统运行的CWS集合。包括28个参考文献，2个表格，4个图表。

Community water systems face pressure to improve performance because of increasing public scrutiny, decreasing financial health, and increasing infrastructure rehabilitation/replacement costs. This pressure requires community water systems to improve accountability to stakeholders relative to all aspects of their performance. However, the current performance assessment and evaluation (PAE) approach of community water systems is highly individualized by service, and it provides little opportunity for benchmark comparisons across the community water system (CWS) sector. Existing PAE frameworks focus on the continuous improvement of core processes internal to a CWS without providing a standard for consistent comparison across services within a geographical region. The research presented in this article hypothesizes that an effective solution to this problem would be to: (1) facilitate public awareness by developing a standard efficiency metric (SEM) parameter for a standardized PAE that would enable stakeholders to compare the performance of their CWS to the regional benchmarks; (2) enhance financial health characteristics by enabling regional management to base resource allocation decisions on uniform performance information about the services in the regional water system; and (3) increase service operating efficiency over the current practice. The SEM parameter described in this article is capable of providing assessment information to the individual community water system provider in order to improve performance. The SEM parameter also enables the comparison and benchmarking of CWSs operating as a regional water system through the standardized PAE framework. As accountability in the CWS sector improves through the use of the SEM parameter, the expected result will be more effective resource allocation decisions across a collection of CWSs operating as a regional system.
