俄亥俄州托莱多市正在利用计算机技术改善其柯林斯公园水处理厂的运营并降低费用。1992年秋天，柯林斯公园的一套计算机化仪器和控制系统全面上线后，柯林斯公园成为中西部最全自动化的工厂之一。这个新系统为托莱多市节省了化学、能源和人力开支。事实上，在该系统的详细设计和后续建设之前完成的一项研究表明，该系统将在六年内自行支付费用。本文描述了该市决定采用该系统的一些原因，并描述了处理机组、配置和处理厂的化学控制回路。 节省能源和人力的细节。作者最后提出了几条建议，供考虑新仪器和控制系统的公用事业公司参考。

The City of Toledo, Ohio, is using computer technology to improve operations and reduce expenses at its Collins Park Water Treatment Plant. After going completely on-line with a computerized instrumentation and control system in the fall of 1992, Collins Park became one of the most fully automated plants in the Midwest. This new system saves the City of Toledo money on chemical, energy, and manpower expenditures. In fact, a study completed prior to the detailed design and subsequent construction of the system, showed that the system will pay for itself in six years. This paper describes some of the reasons the city decided to adopt the system, and describes the treatment train, configuration, and chemical control loops in the treatment plant. Savings in energy and manpower are detailed. The author concludes with several recommendations for utilities considering a new instrumentation and control system.
