The model is then used to <br />provide accurate results for anticipated pipe <br />velocities, system pressures, available fire flows, and <br />system capacity analyses for pipeline sizing, <br />restrictions, and pressure management under <br />differing operational conditions. The model can also <br />be used for fire flow analyses and criticality <br />simulations. <br />IDM has implemented this approach successfully for <br />large, multi- pressure zoned, and hydraulically <br />sensitive systems with similar hydraulic model <br />objectives, including the following sample set of <br />utilities: <br />• City of La Verne -CA, <br />• City of Anaheim -CA, <br />• City of San Jose -CA, <br />• Laguna Beach County Water District -CA <br />• Anchorage Water Wastewater Utilities -AK <br />• Los Angeles Dept. of Water & Power - CA <br />2.

Models used for operational and <br />master planning analyses typically require a 24 to 72- <br />hour EPS catibration, while water quality models <br />typically benefit from longer durations. <br />*Hydraulic & Technical Note related to EPS <br />Calibration: The City's hydraulic profile can be <br />summarized as follows: <br />I� <br />IDMODELING` <br />We can be mare, together. <br />14 <br />
