The City of Athens operates a water treatment plant which supplies an average of 15.5 million gallons per day (mgd) to the residents and businesses of Clarke County and parts of Barrow, Oconee, Jackson, and Madison Counties. As the rapid growth trends of metro Atlanta push eastward, the need to manage water resources in Athens becomes more evident. An important aspect of water resource management is maintaining a reliable supply of water to the customer. Several computer programs are available to aid the engineer in evaluating the adequacy of water distribution systems. The City of Athens uses one such program, developed by the University of Kentucky (Wood, 1980) and based on the Hardy Cross Method, to evaluate the water system's ability to meet demands and to point out hydraulic deficiencies in the distribution system where improvements are necessary. Historical billing records are used by Athens to help make these evaluations with the aid of LOTUS 1-2-3 and D-base software. working interactively with the Hardy Cross computer program.
