本文通过加利福尼亚州东部城市水区（EMWD）的案例研究，回顾了大型AM/FM项目的规划和发展方面。详细介绍了计划流程、预算编制、系统选择、数据库开发和应用程序开发。完成后，EMWD项目将成为AM/FM技术如何应用于大型水和下水道公用设施环境的独特例子。

This paper reviews the planning and development aspects of a large AM/FM project through a case study of the Eastern Municipal Water District (EMWD) in California. Complete details are provided on the planning process, budgeting, system selection, database development and applications development. When completed, the EMWD program will be a unique example of how AM/FM technology can be applied in a large- scale water and sewer utility environment.
