Full Description

The Detroit Water and Sewerage Department (DWSD) provides water and wastewaterservices to the Greater Detroit Metropolitan Area, supplying 43% of Michigan's residentswith water. The DWSD water system consists of 5 water treatment plants, 21 pumpingstations, 3,400 miles of large distribution mains, and a service area covering over athousand square miles. The wastewater system is comprised of approximately 2,900miles of large pipelines and interceptors, 13 pump stations, 3 retention basins, and a verylarge treatment plant (750 MGD avg. flow). Water and wastewater flows are remotelymonitored and controlled.In February 2000, DWSD began a 4-year project to construct a modern, department-wide supervisory control and data acquisition (SCADA) system to allow coordinated operation of all of DWSD's water andwastewater treatment and transport facilities. The contract replaces existing controlsystems, constructs new control systems, refurbishes or replaces aged instrumentation, andinstalls new field instrumentation.One key feature of the new SCADA system is its ability to monitor and analyzepower consumption, enabling energy management strategies to be enacted. For example,DWSD has a large base of backup power generation capability, which the new SCADAsystem can use to shave peak demand and achieve cost savings. This paper discussesall of the SCADA system abilities to improve energy efficiency, and presents how it willachieve those objectives through planning, construction, and into operation. Includes table, figure.
