本powerpoint演示文稿首先简要概述了配水系统的水质。提出了一种新的设计范式，以逆转已经存在的设计概念 它的存在已经将近200年了 设计带有2至4英寸管线的饮用水系统，以及 设计处理火灾的再生水系统 流动和再生水的使用。这种设计条件的转变促进了 经过高度处理的饮用水满足未来的需求 没有内在系统的水质需求 大口径管道引发的问题 需要提供火流。本演示介绍如何制作易于访问的产品 用于集中式和分散式系统的各种用途的水，提供了卫星治疗的标准、治疗技术选择的考虑、改造社区，并提出了在北卡罗来纳大学教堂山分校使用双分配系统的假设示例。包括表格、数字。

This powerpoint presentation begins by providing a brief overview of distribution system water quality. A new design paradigm is presented of reversing the design concept that has existed for nearly 200 years by designing potable systems with 2 to 4-inch lines, and designing reclaimed water systems to handle fire flow and reclaimed water uses. Such a switch in design conditions promotes highly treated potable water to meet future water quality demands without inherent system issues caused by large diameter pipes needed to provide fire flow. The presentation examines producing easily accessible reclaimed water for a variety of uses by centralized vs decentralized systems, provides criteria for satellite treatment, considerations for treatment technology selection, retrofitting a community, and presents a hypothetical example of using dual distribution systems at the University of North Carolina at Chapel Hill. Includes tables, figures.
