The Massachusetts Water Resources Authority (MWRA) contracted with CampDresser & McKee Inc. (CDM) to improve its hydraulic and water quality modelingcapabilities. This paper describes how GIS, SCADA, and fluoride tracer studyresults were used to create and calibrate MWRA's model. As part of this project, asoftware application (MIIGS) was written to create model input files directly from GISand SCADA system data. The GIS provided facility data and the SCADA systemprovided operational data including diurnal demand curves for each customer meter.Preliminary calibration was performed under a variety of conditions ranging fromlow demands to maximum demands. Fluoride tracer studies were conducted topermit a final calibration based on travel time analyses as well as a more precisepressure calibration. To complete the project, a model maintenance procedure wasdeveloped, and training was conducted to ensure the future development of themodel at the MWRA. Includes tables, figures.
