2040 Sanitary Sewer Districts <br />District A <br />Additional trunk sanitary sewer main improvements will be required <br />following the connections of all the existing homes in Sub -districts <br />Al and A2 that are currently on private septic systems. Additional <br />improvements will also be required if the Oneka Ridge Golf Course is <br />re -developed in the future. Trunk system improvements will include <br />the extension of a 12 -inch trunk sanitary sewer from the MCES <br />Interceptor Sewer to the east to serve Sub -district A2 by gravity <br />main. Trunk system improvements for Sub -district A3 include the <br />construction of Trunk Lift Station A3 with a minimum pumping capacity <br />of 425 gpm and the extension of a 10 -inch trunk sanitary sewer from <br />Sub -district A2. <br />District D <br />No additional trunk sanitary sewer main improvements will be required <br />following the connections of all the existing homes and possible <br />redevelopment of Sub -district D1 that are currently on private septic <br />systems. However, system improvements required will include the <br />extension of an 8 -inch sanitary sewer to the northwest to serve Sub- <br />district D1 by gravity main. This sanitary sewer main will be directed <br />to the existing Lift Station No. 10 prior to entering Sub -district D2 and, <br />ultimately, the MCES interceptor at connection point D1. <br />HL 2040 COMPREHENSIVE PLAN UPDATE <br />District F <br />Trunk sanitary sewer main improvements will be required following the <br />possible development of Sub -district E4 and additional sanitary sewer <br />improvements will be required following the development of Sub - <br />districts E5, E6, and E7 that are currently not serviced by the trunk <br />sanitary sewer system. Trunk system improvements will include the <br />construction of new 8 -inch sanitary sewers to serve Sub -district E4, <br />as well as the extension of 8 -inch sanitary sewers within Sub -district <br />E5 which will be directed to the existing sewer within Sub -district E3. <br />Additional sanitary sewer improvements for Sub -districts E6 and E7 <br />will include the installation of 8 -inch sanitary sewer directed to Lift <br />Station No. 4 located in Sub -district E7 prior to entering Sub -district E3 <br />and eventually entering the MCES interceptor at connection point E1. <br />The development and expansion of sewer service into District E will <br />require flows from Sub -districts E4, E6, and E7 to be serviced by <br />Lift Station No. 4. The peak flows generated from these districts are <br />projected to be within the current capacity of Lift Station No. 4. At <br />such a time that development occurs in District V outside of the 2040 <br />MUSA, the trunk sewer main within District E2 along 130th St N <br />would need to be reconstructed to a 42 -inch diameter trunk main from <br />Highway 61 to the MCES interceptor. Lift Station No. 4 would need <br />to be reconstructed to a capacity of 9,600 gpm with the addition of a <br />forcemain from the existing lift station location to Highway 61. <br />If <br />:111280McNYA <br />for review only <br />District G <br />No additional trunk sanitary sewer main improvements will be required <br />following the possible development of Sub -district G1 that is currently <br />not serviced by the trunk sanitary sewer system. To expand sewer <br />service into Sub -district G1, system improvements will be required and <br />include the extension of 8 -inch sanitary sewers to the west and south <br />from Sub -district G2 to serve Sub -district G1 by gravity main, which <br />will then outlet to the MCES interceptor at connection point G1. <br />COMPREHENSIVE SANITARY <br />SEWER PLAN <br />W <br />
