Description:
A variety of computer based models have been developed and used by the water industry to access the movement and fate of contaminants within the distribution system. uch models include: ynamic and steady state hydraulic models which simulate the flow quantity, flow direction, and pressure in the system, steady-state water quality models and flow tracing models which determine the movement of contaminants, their flow path and travel times through the network; and dynamic water quality models which simulate the movement and transport of substances in water under time varying conditions. ach type of model serves a particular purpose in the assessment of water quality in a distribution system and thus, should be considered as a tool available to the engineer and planner who wishes to investigate water quality related issues in a distribution system. his paper will briefly review the results of an extensive field study conducted by the U.S. Environmental Protection Agency and the North Penn Water Authority, which resulted in the development of a series of models that can be used to study contaminant propagation in a water distribution system. n example is presented in which the model developed by the U.S. EPA was applied to explore the movement of a waterborne contaminant found in the Cabool, Missouri distribution system. inally, an extension of this work to a large drinking water utility, the South Central Connecticut Regional Water Authority will be discussed and the progress to-date discussed.
