Abstract: Since December 1972, the Corps of Engineers, Savannah District, has been conducting a water resources study in metropolitan Atlanta, Georgia. The study is a joint effort of the Corps, Atlanta Regional Commission, Georgia Environmental Protection Division, and U.S. Environmental Protection Agency. One of the objectives of the Metropolitan Atlanta Water Resources Study is to develop regional alternatives for wastewater treatment and management in the 7-county area. In conjunction with this effort, broad regional alternatives for treatment of point wastewater sources were developed, including various size, number, and location of treatment plants and various treatment levels. In addition, an evaluation was conducted of the magnitude and treatment options of non-point pollution sources, including urban runoff and combined sewer overflows. During late 1974, the four agencies conducting the Atlanta study recognized the limitations inherent in the steady-state water quality computer models available for evaluating wastewater management strategies. A related question concerned the amount and validity of data available for water quality analysis, including the input data and cost-effectiveness of structural and non-structural management techniques. Subsequently, during early 1975 the four agencies initiated discussions with the Corps' Waterways Experiment Station (WES) in Vicksburg, Mississippi and the Hydrologic Engineering Center (HEC) in Davis, California regarding assistance in evaluating water quality and computer modeling needs for metropolitan Atlanta. In January 1975, the Hydrologic Engineering Center was engaged to adapt a state-of-the-art water quality computer model for one of the major rivers in Metropolitan Atlanta and to demonstrate the potential for assessing the impact of selected pollution sources on water quality in a receiving stream. The computer program, "Water Quality for River-Reservoir Systems" (WQRRS) was selected by the four study agencies and was to be adapted by HEC for the 116-mile reach of the Chattahoochee River between Buford Dam and the headwaters of West Point Reservoir. The location map shown in figure 1-1 defines the boundaries of the study area.
