切斯特菲尔德县公用事业公司（CCU）为弗吉尼亚州切斯特菲尔德县的78915名客户提供供水服务，并为65822名客户提供废水处理服务。该部门管理着2900多英里的供水和废水管线。操作和维护卡车中地图册数量的增加、绘图存储空间的减少、介质的恶化，以及对更快记录检索的需求，表明需要另一种存储介质。本文介绍了CCU便携式公用事业管理应用程序的开发；其目标是为现场工作人员提供基于Arc View的应用程序，以访问地理信息系统（GIS）数据和包含阀门位置图的AutoCad绘图文件。本文还简要讨论了一种电子文档管理系统，用于对所有地图和相关记录进行成像。

Chesterfield County Utilities (CCU) provides water service to 78,915 customers and wastewater service to 65,822 customers in Chesterfield County, Virginia. The department manages more than 2,900 miles of water and wastewater lines. Increasing numbers of map books in the operations and maintenance trucks, diminishing space for drawing storage and deteriorating media combined with a need for faster records retrieval signaled the need for another storage media. This paper describes the development of CCU's portable utilities management application; the goal of which was to provide field crews with an Arc View-based application to access geographic information system (GIS) data and AutoCad drawing files containing valve location diagrams. The paper also briefly discusses an electronic document management systems for imaging all maps and related records.
