The Advantages of a Calibrated Water Model During (and Before) a Water Main Break Dan Barr, PE Burgess & Niple, Inc.
What Are the Advantages? ,[object Object],[object Object],[object Object],[object Object],[object Object]
Determining the Impact of a Leak ,[object Object],[object Object],[object Object]
Determining the Impact of a Leak (cont.) ,[object Object],[object Object],[object Object]
Determining the Impact of an Out-of-Service Main ,[object Object],[object Object],[object Object],After the main is isolated and the leakage stopped, the model can predict the system’s performance when the main is out of service.
Deciphering Abnormal Results from the Incident ,[object Object],[object Object],[object Object],[object Object],When the model results do not align with the field results, use the model to:
Optimizing the System Before a Break ,[object Object],[object Object],[object Object]
Summary ,[object Object],[object Object],[object Object],Using calibrated water models during a water main break can minimize:
