Computerizing Pipeline Design

Computer programs are available that will almost exactly simulate the operation of a water distribution system. Accurate basic data on the existing water distribution system are essential to set up a reliable mathematical model. Extensive field tests are necessary to obtain flows through major trunk mains, coefficients of carrying capacity of the pipelines, consumption rates in the various sections of the system, and to determine water available for fire protection. The most economical design will fully utilize existing facilities to the maximum. The mathematical model must be checked against actual operation of the water system before computerized design of additional pipelines and other facilities are undertaken. Computer print-outs should show all essential input data and the results obtained in a form which makes it a relatively easy task for analyzing by the design engineer. Optimization of cost and complete computerized control of a water system are in the future.
