20世纪90年代的水/废水SCADA系统正在利用计算机硬件和软件以及开放系统环境的进步，将实时和历史公用设施数据应用到超出运营范围的应用中。SCADA系统架构也可以配置为应用网络计算机系统进行分布式监控。本文定义了布雷瓦尔德县水/废水部门如何利用多个互联计算机系统实施分布式SCADA系统。作者用布列瓦尔德县系统的背景信息设置了场景，接着列出了SCADA项目的10个目标。根据对远程站点位置、需要信息的位置、通信路径、系统响应时间和可靠性的要求，考虑了三种类型的系统架构——独立、集中和分布式。 其他设计决策围绕着创建数据库、远程终端单元、供水和废水处理厂集成、通信系统集成、软件应用程序和其他系统的网关；对每一个问题都进行了简要讨论。SCADA系统的实施包括供应商选择、过渡计划和公用事业员工准备；本文还对每一个问题进行了简要讨论。图中显示了项目模型、三种类型的SCADA体系结构、通信系统镜像SCADA体系结构、报告结构、硬件设置和人员指挥链。

Water/Wastewater SCADA systems in the 1990s are taking advantage of advances in computer hardware and software and open systems environments to apply real-time and historical utility data to applications extending beyond operations. The SCADA system architectures also can be configured to apply networked computer systems for distributed monitoring and control. This paper defines how the Brevard County Water/Wastewater Division is implementing a distributed SCADA system with multiple interconnected computer systems. The author sets the scene with background information about the Brevard County system, the goes on to list the 10 objectives of the SCADA program. Three types of system architecture--stand alone, centralized, and distributed--were considered in light of requirements for location of remote sites, locations where information is required, communications paths, system response time, and reliability. Other design decisions centered around creation of the database, remote terminal units, water and wastewater plant integration, communication system integration, software applications, and gateway to other systems; each of these is briefly discussed. Implementation of the SCADA system consisted of vendor selection, transition plan, and utility staff preparation; each of these is also briefly discussed. Figures show the project model, the three types of SCADA architecture, the communication system mirroring SCADA architecture, a reporting structure, the hardware set up, and the personnel chain of command.
