This article discusses significant advances in the use of digital computers in the analyses of three separate water distribution systems. These advances include: having the computer set the initial flow pattern; speeding the process of convergence by means of special control loops and a method of overrelaxation; utilizing internal notations of variables to permit flexibility of input data; and, providing the capability of handling large networks at modest cost. The systems which were analyzed are municipal water systems located in St. Louis County, Missouri. These systems and the approximate populations served are Florissant, 50,000; Kirkwood, 30,000; and Webster Groves, 30,000. In each case, the analyses were conducted as a part of an overall study of needs for improvement or expansion of the systems and served as a valuable tool in determining system weaknesses and evaluating the effects of proposed improvements to the system.
