Guidebook helps utilities in choosing, implementing water quality simulations in systems
The American Water Works Assn. (AWWA) announced the publication of the new edition of its “Modeling Water Quality in Distribution Systems” guide.
As water flows through the distribution system to the consumer, it may go through unwanted changes in quality. Computer modeling is a realistic simulation of the water quality in utility distribution systems, tracking the water as it moves through the system to determine where and how quality might be compromised. By utilizing this technology, utilities can understand and prevent changes in water quality, ensuring that the tap water that reaches customers is the same high quality water that left the treatment plant.
Written by modeling expert and EPANET developer Robert M. Clark, “Modeling Water Quality in Distribution Systems” guides utilities in choosing and implementing a realistic computer simulation of a wide range of operational and design variables—including various scenarios to model and monitor TTHMs, disinfectant decay, chemical reactions, supply-and-demand over time, hydraulics, tank mixing, blended waters, pipe system layouts and many other parameters.
