and every 24 hour period. Further, it is understood that the potential customers with greatest irrigation needs (Le. John's Island, Windsor, Sea Oaks, Orchid) have the capacity to store reuse water onsite, which will provide additional assurances that the system will not be burdened with significant periods of high peak demands. Attached within Appendix C "WaterCAD Model Results" are results of several evaluations summarized as follows: Scenario A: This models the current IRCDUS flow allocation (using data from December 2017 to November 2018. (Total flow allocation of 1.097 MGD: current 0.585 MGD flow to north barrier island, and available 0.512 MGD, diverted from the manmade wetlands to JI): A-1. (refer to Appendix C, p. EX -01). Existing 16" transmission line on CR 510 to A -1-A, which feeds a new 16" Transmission line south to Sea Oaks and a new tank (3 MG). New Pumps at Sea Oaks to distribution mains: 8" exist line north to Windsor, 12" new line south to Old Winter Beach Road -(Tank delivery: 83.3 psi / Orchid : 75.4 psi / JI : 83.0 A-2. (refer to Appendix C, p. EX -02). Existing 16" rhtsmission ' e on CR 510 to A -1-A, which feeds an existing 8" line north to Windsor, and new " line outh to Sea Oaks and a new tank (3 MG). New pumps to distribution mains: 8 x i e north to Disney, 12" new line south to Old Winter Beach Road. -(Tank delivery: 83.7 psi / Orchid : 80.5 A-3. (refer to Appendix C, p. EX -03). ll re se o island fed from Hobart Tank and pumps. No new tank or pumps at Sea Oak4.

T e 6 reduces to a new 12" line from Sea Oaks south to Old Winter Beach Ro -(No Tank / Orchid: • si. / ' I ; a 2. • si) Note All models provide near y t e same high delivered pressures. A-3 provides adequate flow and delivery pressure without a ank or pumps. Scenario B: This models an estimated flow allocation for all current and potential future reuse customers within the IRCDUS service area and additional flow to the John's Island development. The basis of the flow allocation was estimated to be the sum of: the flow allocations of all developments with an existing SJRWMD CUP, plus an estimated flow allocation of 1.0 MGY per acre of irrigated area for developments without a SJRWMD CUP, plus 1.0 MGD flow allocation for John's Island development. (Total flow allocation of 2.964 MGD: estimated 1.964 MGD flow to north barrier island communities within IRCDUS service area, and an additional 1.0 MGD to JI): B-1. (refer to Appendix C, p. EX -04). Existing 16" transmission line on CR 510 to A -1-A, which feeds a new 16" Transmission line south to Sea Oaks and a new tank (3 MG).
