FINAL <br />Hydrant Flow and C- factor <br />Testing Plan <br />tp4t•xuua a•achc•unty W a,•C 0 €strict <br />p!Mgi; Ping- ,Ap".ba *144e1, <br />AWWA Manual of Practice for Distribution System <br />Modeling, M32 (Paul Hauffeo, Project Manager for <br />this Project, co- authored this Manual of Practice). <br />Applications and Benefits: 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 ofAnaheim•CA, <br />• City of San lose -CA, <br />• Laguna Beach County Water Dlstrlot•CA <br />• Anchorage Water Wastewater Utilities-AK <br />• Los Angeles Dept. of Water &Power - CA <br />nw..w..ex,�wtm+,ro�..eew mw «o <br />lA01 €uFCaNtatrs. <br />HYpNNrrt W✓ RSflML.«... e.«... e...... � .»....« .....................m„9 <br />liroaw* rtmatmxerMroeaur7M+ nwnw .... „._, ®_.®..__.„._,_.®...il <br />UO OFAPP MIS <br />A (F+dNtI61WfSMMto <br />a CIxMirM tq'awxM+t{ <br />4 kmem.etaaYmku�ams -• <br />P 5v»vtC.P+em+YUeiHV taitC�v YOm <br />t gweuu�aapmvims+>.uamxrc:a, <br />IOM has provided a sample Calibration Plan, as <br />completed for Laguna Beach Water District, in the <br />Figure above. <br />This approach will provide the City with a very high <br />level of confidence that the model is capable of <br />accurately responding to a variety of conditions in the <br />distribution system. It will also provide a minimum set <br />of operational controls that will provide significant <br />flexibility to conduct subsequent planning and <br />operational analyses. <br />0 Technical Memorandum (TM) #5 <br />Fxtended Period simulation Calibration <br />Plan. Extended Period Simulation (EPS) <br />calibration typically consist. of 24 -hour to <br />7 -day calibration periods depending on the ultimate <br />uses for the model. Models used for operational and <br />master planning analyses typically require a 24 to 72- <br />hour EPS calibration, while water quality models <br />typically benefit from lodger durations, <br />*Hydraulic & Technical Note related to EPS <br />Calibration: The City's hydraulic profile can be <br />summarized as follows: <br />We can be mare, together. <br />2501-18 <br />
