District I Additional trunk system improvements following the development of Sub -District 11 include the extension of a 10 -inch trunk main to the service area. No additional trunk sanitary sewer main improvements will be required following the possible development of Sub -districts 15 and 16 that are currently not serviced by the sanitary sewer system. However, system improvements will be required and include the extension of 8 -inch sanitary sewers within each sub -district to serve each by gravity main. A portion of Sub -district 11 wastewater flows will be directed to Sub -district 12 and eventually outlet to the MCES interceptor at connection point 11. Sub -district 15 wastewater flows will be directed to Sub -district 14. The extension of sanitary sewer to Sub -districts 15 and 16 would result in the total peak flows entering Lift Station No. 2 exceeding the capacity of the lift station. Thus, the capacity of Lift Station No. 2 pumps would need to be upgraded from 400 gpm to at least 420 gpm before total sewer service expansion into Sub -districts 15 and 16. Sub -district 16 sanitary sewer improvements will consist of the extension of an 8 -inch sanitary sewer and the construction of Lift Station 16 with a minimum pumping capacity of 115 gpm. Wastewater flows from this lift station will then be directed to Sub -district 14 prior to entering the MCES interceptor at connection point 11. District J To serve the future commercial and low density residential in Sub- district J5, the extension 8 -inch sanitary sewers will be required, which can connect to the existing 10 -inch trunk sewers in Sub -districts J2 and J4. District K An 8 -inch sanitary sewer will be expanded to serve the future medium density residential Sub -district K3. This district's flows will be connected to and flow into existing extension sewer lines in Sub- district K2. To serve the future low density residential Sub -district K6, the extension of 8 -inch sanitary sewer will be required from Sub -district K4. District L No additional trunk sanitary sewer main improvements will be required following the possible development of Sub -districts L2 and L3 that is currently not serviced by the trunk sanitary sewer system. However, system improvements will be required and include the extension of 8 -inch sanitary sewers to the east from Sub -district L1 to serve Sub- district L2 by gravity main. Sub -district L3 improvements will include the extension of an 8 -inch sanitary sewer from the MCES Interceptor Sewer. District N. No additional trunk sanitary sewer main improvements will be required following the possible development of Sub -districts M2 and M3, currently not serviced by the trunk sanitary sewer system. However, system improvements will be required and include the extension of 8 -inch sanitary sewers to the south and east from Sub -district M1 to serve the districts by gravity main. District N Trunk sanitary sewer main improvements will be required following the possible development of Sub -district N1 and additional sanitary sewer improvements will be required following the development of Sub -district N7, currently not serviced by the trunk sanitary sewer system. Trunk system improvements for Sub -district N1 will include the construction of Lift Station N1 with a minimum pumping capacity of 220 gpm and the extension of a 10 -inch trunk sanitary sewer from Sub -district N4. System improvements will include the extension of 8 -inch sanitary sewers to the north to serve the eastern portion Sub -district N3 by gravity main which will be directed to the existing Lift Station No. 8 located within Sub -district N2. Additional sanitary sewer improvements for Sub -district N7 will include the installation of 8 -inch sanitary sewer directed to Sub -district N6 prior to entering the MCES interceptor at connection point N1. Service to Sub -district N8 will be accomplished through the extension of 8 -inch sanitary sewer from Sub -districts N6 and N9. .0� ,r I 2040 COMPREHENSIVE PLAN UPDATE DRAFT Dec 14-17 COMPREHENSIVE SANITARY A SEWER PLAN for review only
