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.
