CMP Part 4B. Sanitary Sewer Plan Projections for MCES Interceptors. The MCES interceptors forecasted flow are listed in the table below. The interceptors are in series: 8352A->7113A->7113 and 8567->7113. Note the flow depicted is only Orono generated flows that are received within Orono and Long Lake. Orono generated flows that go to Wayzata or Plymouth are not included as they ultimately end up at interceptors 7018-2 and 7027-1. Also,note that the total flow listed is only the flow generated in Orono and does not include any flows from neighboring communities that may also discharge into the particular interceptor. Table 4B-8: Interceptors Flow (MGD) MCES Interceptor 2010 2020 2030 2040 8352A and 7113A 0.11 0.12 0.16 0.17 8567 0.43 0.44 0.45 0.52 7113 0.55 0.57 0.61 0.69 Private Systems Rural areas of Orono will continue to be served by individual sewage treatment systems (ISTS). Sanitary sewers and other urban services will not be extended into the rural area to promote new development or expansion of urbanization. The city does not foresee much increased density in the rural area requiring additional ISTS. Within the rural area, nearly all water supplies are provided by individual wells and most sewage treatment is provided by individual sewage treatment systems("ISTS"). A number of specific neighborhoods within the Rural Area have been or will be provided with municipal sewers to solve neighborhood problems or to protect the lakes, but no other urban services are planned for these areas.
