In full development, MWIS might link together all urban water functions to be operated as a single, unified system. This report presents an analysis of an investigation into the specific problem of controlling overflows from combined sewer systems in order to reduce this source of receiving water pollution. The technical and nontechnical aspects of the problem discussed include: the initiation of a Real-Time Automation and Control System (RTACS) by means of a simulation model for use in the design of the components of the RTACS, the initial criteria for use in the development and operation of an RTACS, and the technical and nontechnical feasibility of an RTACS for combined sewer systems and possible further application to overall urban water systems. The report is based on a series of technical reports which are available separately. They include: an inventory of existing automation, control and intelligence systems; a report on computer and control equipment; a field report on an actual control system located in Minneapolis-St. Paul; an evaluation report of control schemes; a social and political feasibility report; a technical report on the RTACS model; a guidelines report for managers; and additional analysis on the effect of urban size and on research and development needs.technical reportsengCopyright and other restrictions may apply.
