Engineering Modeling Applications
Models of water distribution systems have a long history — likely longer than most realize. However, in recent decades, the functional capabilities, user interfaces, and processing algorithms have markedly improved. While many professionals in the water sector may have reviewed or even developed a model in the past, today's practice of modeling has evolved significantly, and with the proliferation of advanced technology throughout the water sector, tomorrow's engineers and operators will commonly use even more advanced models of our vital water infrastructure.

Hydraulic Modeling
Hydraulic models are typically developed to show a snapshot of a utility’s system, for master planning purposes or to run “what if” scenarios. Distribution system models are being used more routinely to evaluate issues having to do with operations, energy use, vulnerability, and water quality, in addition to their traditional applications. As the need to more accurately model systems proliferates, the models increase in complexity and level of detail.

Optimizing Water Quality & Treatment
Water quality modeling is a powerful tool for analyzing the fate and effect of contaminant transport in drinking water plants and distribution systems.

Transient Modeling
Transient modeling focuses on oscillations in piping systems caused by a sudden change in system operations, such as pump failure or rapid valve closure. Modeling is used to identify mitigation measures for potentially damaging high or low-pressure waves caused by a transient event. The starting point of a transient model is generally a well-calibrated or depictive hydraulic model.
