Defining Regional Water Distribution System Models.

Key Takeaways: What defines a regional water distribution system? An AWWA committee sorted through the characteristics of systems and their respective models to come up with a clear classification. Regional water distribution models are broken into two categories: regional transmission and regional emergency supply, with many models landing somewhere along the spectrum. A close examination of four regional water systems revealed the unique attributes and numerous considerations that make developing and maintaining hydraulic models complex. [ABSTRACT FROM AUTHOR]
