1987年，盐湖城大都会水区完成了一项系统改进总体计划，评估了计算机化仪表和控制系统的实施情况。该地区从总体规划中意识到，水资源法规正在发生变化，新法规将要求该地区的处理设施提高性能。CH2M Hill于1990年被选为捷运局的顾问，以帮助捷运局用最先进的新系统替换现有的仪表和控制系统。手动功能可以自动化，以提高工厂的运行性能。人工记录将被计算机生成的报告所取代，供地区和其他实体使用。过滤器的手动反洗将被自动反洗取代，以提供对每个过滤器反洗的更均匀性和控制。 化学加料系统将由计算机监控，目的是优化处理过程中的化学品添加。设计和实施标准在该地区与CH2M Hill之间的互动研讨会上进行了介绍。一旦这些标准被接受，设计将规范和计划与既定的运营、技术和预算标准相匹配。升级后的仪表和控制系统使操作人员能够更快地响应不断变化的操作条件。控制系统的实施已经实现了项目最初构思时预期的效益。这些能力包括满足现有运营需求的能力以及响应未来需求的能力。

In 1987, the Metropolitan Water District of Salt Lake City completed a Master Plan of System Improvements that evaluated the implementation of a computerized instrumentation and control system. The District realized from the Master Plan that water regulations were changing and that new regulations would require improved performance from the District's treatment facilities. CH2M Hill was selected as the District's consultant in 1990 to help the District undertake replacement of its existing instrumentation and control system with a new state-of-the-art system. Manual functions could be automated to improve the plant's operational performance. Manual record-keeping would be replaced by computer-generated reports for District and other entities' uses. Manual backwashing of filters would be replaced with automatic backwashing to provide more uniformity and control over the backwashing of each filter. Chemical feed systems would be monitored and controlled by the computer with the goal of optimizing the addition of chemicals in the treatment process. Design and implementation criteria were presented in interactive workshops between the District and CH2M Hill. Once these criteria were accepted, the design matched specifications and plans to the established operating, technical, and budgetary criteria. The upgraded instrumentation and control system provides operational personnel with the ability to respond much more quickly to changing operational conditions. Implementation of the control system has resulted in achievement of the benefits foreseen when the project was first conceived. These include the ability to meet existing operational needs as well as the capability to respond to future requirements.
