Revitalization of Urban Water Supply and Distribution Systems: Detroit and Phoenix Case Studiesby Thomas W. Hurdle, Harza Engineering Co, Arizona, Office, Phoenix, AZ, USA,
Abstract: In 1980 the people in the Detroit Water and Sewerage Department were asking themselves the kind of question that is facing the managers of many municipal utilities in this country these days. This kind of question is facing most cities. Detroit's question went like this: We have this old water treatment plant which is in very bad repair. It was designed to produce water at 350 mgd (1320 ml) but can now only produce 230 mgd (870 ml) on its best day. Its superstructures are bad, and much of its equipment is obsolete or out of service. Should we repair this plant, or should we abandon it, and if we abandon it should we build added capacity at this site or somewhere else, and if somewhere else, where?
