The interceptors are <br />in series: 8352A->7113A->7113 and 8567->7113. Note the flow depicted is only Orono <br />generated flows that are received within Orono and Long Lake. Orono generated flows <br />that go to Wayzata or Plymouth are not included as they ultimately end up at interceptors <br />7018-2 and 7027-1. Also, note that the total flow listed is only the flow generated in Orono <br />and does not include any flows from neighboring communities that may also discharge into <br />the particular interceptor. <br /> <br />Table 4B-8: Interceptors <br />Flow (MGD) <br />MCES Interceptor 2010 2020 2030 2040 <br />8352A and 7113A 0.11 0.12 0.16 0.17 <br />8567 0.43 0.44 0.45 0.52 <br />7113 0.55 0.57 0.61 0.69 <br /> <br />Private Systems <br />Rural areas of Orono will continue to be served by individual sewage treatment systems (ISTS). <br />Sanitary sewers and other urban services will not be extended into the rural area to promote new <br />development or expansion of urbanization. The city does not foresee much increased density in <br />the rural area requiring additional ISTS. Within the rural area, nearly all water supplies are <br />provided by individual wells and most sewage treatment is provided by individual sewage <br />treatment systems ("ISTS"). A number of specific neighborhoods within the Rural Area have been
