Multi-Network DCS Approach Allows Phased Installation and Sets Stage for Optimum Asset Management
Abstract:The Metropolitan Water Reclamation District of Greater Chicago [MWRDGC or District] operates one of the largest wastewater treatment agencies in the world. In 2006, MWRDGC began a comprehensive upgrade program of its existing instrumentation and process control systems at both the Stickney plant and at various remote locations. The new system would be required to not only replace aging instrumentation and controls at the Stickney plant, but also allow the District's other plants, remote pumping facilities, and storm water retention reservoirs to become an integral part of unified system architecture. The vast scope of the necessary upgrades required the District to divide the effort into a phased approach spread over a number of years. The phased approach for installation of a multiple network backbone, consequences to the approach, benefits, and impacts to Plant Operations are reviewed.
