20世纪80年代末，曼彻斯特水厂（新罕布什尔州）意识到，它保存的大量信息越来越难以管理。本文讨论了MWW为实现计算机化绘图和管理系统所采取的步骤。本文还详细介绍了MWW的新系统。描述了现有的配电系统记录。确定了管理目标。本文的大部分内容描述了所选软件和硬件的具体功能，以及MMW为实现既定目标而使用的方式。交互模块包括设施管理、工作管理和图形管理。 工作管理进一步细分，包括请求/投诉、预防性维护、纠正性维护和工单、记录工单和工单历史分析。如果水务公司自己执行大部分工作，实施成本从45000美元到450000美元不等，或者雇佣顾问完成工作的成本从450000美元到450000美元不等。

In the late 1980s, the Manchester Water Works (New Hampshire) realized that the vast amounts of information that it maintains was becoming increasingly difficult to manage. This paper discusses the steps MWW took to implement a computerized mapping and management system. The paper also takes a close look at MWW's new system. Existing distribution system records are described. Management goals are identified. The bulk of the paper describes the specific capabilities of the selected software and hardware and the ways they will be used by MMW to meet its established goals. Interactive modules include facilities management, work management, and graphics management. Work management is further broken down to encompass areas of requests/complaints, preventive maintenance, corrective maintenance and work orders, logging work orders, and work order history analysis. The cost of implementation is anywhere from $45,000 if the water utility performs much of the work itself, or $450,000 to hire a consultant to do the work.
