Understanding Water Age in Distribution Systems with EPANET

Abstract

Modeling water age is a simple approach, by means of a readily measurable parameter, to rapidly assess a water distribution system's (WDS's) general water quality.Used correctly, the US Environmental Protection Agency's EPANET program can model water age with accuracy, and the results can help in designing, improving, or operating a WDS.The newest edition of EPANET added mass balance calculations and has improved computational time, mass balance performance, and overall model stability.
