Two separate connections will service the onsite fire system, both originating from an existing 12" Polyvinyl chloride (PVC) water line running underneath I Innovation Way. Each fire line connection will utilize an 8" double detector check valve (DDCV). The two connections service an onsite looped fire system consisting of an 8" line that will serve the fire sprinklers and seven separate hydrants around the site. I CRITERIA AND METHODOLOGY The modeling of the onsite fire service lines was completed using the EPANET 2.0 program (EPANET). Usage of the water and sewer plans provided the scaled distances for the project. The schematic used in EPANET can be found in Attachment 1. Head Loss Across Fittings I Minor loses encountered in the Ductile Iron Pipe (DIP) fittings along the pipelines were neglected in the model (i.e. elbows, tees, etc.). The head loss (HL) across each backflow apparatus was addressed and modeled using the method described below. I The Watts 8" double check detector assemblies (DCDA) were modeled as a general purpose valve (GPV) in series with a check valve. The HL curve can be found on the specification sheet I for the Watts DCDA on Attachment 2. This information was used to develop Figure 1 below, which displays the HL curve created for usage in EPANET to model the flow within the system. Additional information for the proposed backflow devices can be found on Attachment 2. I I I I I I I I I Curve Editor Curve ID Description - iatts DDCV 8' Curve Type Equation JHEADLOSS J J --- -.

Modeled Demand Flows An individual scenario was run in order to ensure the onsite hydraulics can supply adequate flow to the system during a fire event. The required fire flow demand of 1,500 gallons per minute (gpm) for the onsite hydrants was provided by the City of Carlsbad Fire Marshall. Scenario 1— For this analysis, an assumed demand of 1,500 gpm was required for the hydrant furthest from the building connections (please see Attachment 1 for selected hydrant). Tie-In Pressures Available Existing flow and pressure data from the public system in Innovation Way was taken from a flow analysis performed by the City of Carlsbad Fire Department on September 24, 2015. To model this scenario in EPANET, the available pressure was modeled as two reservoirs with a total head equivalent to the Static Pressures given in the analysis provided by the City. This pressure test data can be found in Attachment 3 to this report, and is summarized in the table below.

Pipe velocities shall not exceed 10 feet per second (fps). Scenario 1 Maximum velocity - For this scenario, the highest velocity found in the system is in Pipe 36. This velocity was recorded as 9.57 fps. See Attachment 4. Minimum Pressure - For this scenario, the minimum pressure in the system is found in Junction 13. This pressure was recorded as 67.55 psi. The residual pressure at the building connections were 73.25 psi and 73.30 psi.
