本powerpoint演示文稿首先列出五个主要讨论点。在配水系统中，首先是关闭阀门，其次是关闭阀门的原因，以及关闭阀门的影响。现场测试和模型校准是第二个主题，包括水力坡度线测试， 传统的全系统测试，以及 典型的传导干线干线（e12英寸）。本文总结了华盛顿郊区一家公用事业公司的案例研究。本文介绍了新测试方法的成本影响，以及业务流程集成。包括数字。

This powerpoint presentation begins by listing five main discussion points. Closed valves in water distribution systems is the first, along with causes of closed valves, and closed valve implications. Field testing and model calibration is the second topic and includes hydraulic grade line test, traditional system wide test, and typically conducted trunk mains (e12 inch). A case study of a suburban Washington, D.C. utility is summarized. Cost implications of newer test methods are presented, along with business process integration. Includes figures.
