Hydraulic and chemical models of water distribution systems can be interfaced with on-line sensors to provide a highly accurate and up-to-the-minute description of system operation. Such models can be used for real-time monitoring and diagnostics. They can also be used to improve system operation, evaluate replacement or system expansion options, solve pressure/flow problems, and solve water quality problems. The installation of a real-time sensor-enabled water distribution system model at an Army installation will be described. Concepts for the use of dynamic utility system models as part of an overall “virtual installation” planning and operations tool will be discussed.
