The analysis was performed by generating a <br />computer model using Cybernet, a program for the design and analysis of pressure <br />flow pipe distribution and collection systems. <br />Creating the computer model included collecting information on the existing system <br />such as pipe layout and sizes, location and normal position of system valves, <br />system ouffalls to reuse water receiving lakes, and effluent pump curves. We <br />evaluated the capacities of over 14 miles of transmission and distribution mains, <br />effluent pumps of two interconnected treatment plants, three existing reuse water <br />users, and the potential for three future users. We evaluated two scenarios. The <br />first simulated two WWTPs interconnected by a common IQ transmission main. <br />This was done to determine the pumping potential of the plant farthest out in the <br />system. The second scenario simulated one plant pumping IQ effluent to the other <br />plant and the flows being combined and then repumped. <br />The purpose of the model was to determine the hydraulic capacity of the six -mile <br />transmission main, pumping capacity of each plant based on the existing pump <br />curves, the possibility of interconnecting the two plants, and various operating <br />conditions at the IQ users. <br />Consolidated Sanitary Sewer and Reclaimed Water Systems Hydraulic Analysis, Martin County, FL <br />We conducted a hydraulic analysis of the Martin County Consolidated North and South Sewer Force Main System and reclaimed <br />water distribution system. The analysis was performed by generating a computer model using Cybernet, a program for the design and <br />analysis of pressure flow pipe distribution and collection systems. We analyzed the consolidated systems (north and south) for both <br />existing and future conditions. <br />Creating the computer model included collecting information on the existing system including pipe layout and sizes, location and <br />normal position of system valves, lift station wet well capacities, lift station pump curves, and reclaimed water transfer pumps. We <br />evaluated the capacities of 115 lift stations based on pump curves and piping configuration. We also evaluated average pump run <br />times based on the county's telemetry system. <br />We performed field tests to correlate the computer model to <br />actual operating conditions. We then calibrated the model <br />according to the field test results. The purpose of the model <br />was two -fold. The first was to determine an equalization of <br />flows in the South system to two different wastewater treatment <br />plants. The ability to convey additional flows to the Tropical <br />Farms Wastewater Treatment Plant helped remove the <br />limitations placed on plant capacity. Force main and lift station <br />improvements were recommended to allow additional flow to <br />the Tropical Farms Wastewater Treatment Plant. The second <br />purpose was to use the model as a tool in establishing capital <br />budgets for improvements to the north and south systems. These <br />improvements included items for more efficient system operation <br />as well as planning for future growth and demands. Future <br />conditions were determined based on projected population <br />growth and land uses over the next 20 years. <br />RFG,a -0,� <br />OY26=1.14-0 Smny Isles Bear.Ca uiv RNessinsl Senars.tr <br />Kimley )))Horn <br />
