CMP Part 4B. Sanitary Sewer Plan <br /> EXISTING SANITARY SEWER SYSTEMS <br /> Land Use <br /> Historic development patterns have resulted in a city which is partially urban and partially rural. <br /> The citizens of Orono have decided that a long range planning objective of the City is the <br /> permanent retention of the rural community. This objective is in line with the existing developed <br /> density of the area, with the similar plans of other cities abutting the rural area, and with the <br /> legislative intent of metropolitan planning such that expensive urban services not be over extended <br /> into undeveloped areas. <br /> Sewering of the urban area was is necessary. The character and historic density of land use in the <br /> existing urban area of Orono,coupled with its general proximity to Lake Minnetonka both required <br /> and economically justified the installation of sanitary sewer to alleviate existing health and <br /> environmental problems. <br /> Rural lakeshore areas within the Shore land and within the Metropolitan Urban Service Area <br /> tMUSA)have been provided with municipal sewer service upon request. Residences, existing or <br /> proposed within the designated Shore land Overlay District and within the MUSA for which <br /> municipal sewer service was requested were and shall be provided with municipal sewer. <br /> However, this policy will not preclude development of such areas using fully conforming <br /> Individual Sewage Treatment Systems. <br /> Metropolitan Council Facilities <br /> The Metropolitan Council Environmental Services LMCESowns, operates and maintains <br /> interceptor sewer and facilities in Orono as indicated in the map at Appendix Amap 4B-1. The <br /> Orono system is serviced by MCES meters; M431 and M435. Sewage flows from southern Orono <br /> are metered at MCES Meter M435. Flows from north central Orono are metered at MCES Meter <br /> M431. MCES maintains six lift stations within Orono; L44, L45, L46, L49, L59 and L60. All <br /> sewage outflow from Orono is conveyed to and treated at MCES's Blue Lake Treatment Plant on <br /> the Minnesota River in Shakopee. Orono's sewer service capacity is limited by the capacity of the <br /> intervening interceptors including the Orono-Long Lake Interceptor, and not strictly by the <br /> capacity of the Blue Lake Facility. A history of the MUSA expansion can be found on Map 4B- <br /> 2. <br /> Orono Sanitary Sewer System <br /> The City of Orono owns, operates and maintains municipal sanitary sewer facilities as indicated <br /> on the Map bel4ow4B-3. Orono's sanitary sewer system currently consists of approximately <br /> 245,131 ft of Sewer Main, 80,530 ft of Force Main, 1292 Manholes and 44 lift stations, of which <br /> a majority was built within the last 50 years. The City of Orono's existing Sanitary Sewer System <br /> limits are defined by the boundaries of the Municipal Utility Service Area (MUSA). Because of <br /> topography and historic development patterns, the Orono municipal sewer system includes a <br /> number of disconnected sections which can be categorized into 5 distinct service areas. In addition <br /> the topography of the area has resulted in the City constructing 44 Lift Stations. <br /> Orono System is at Appendix B. <br /> City of Orono Community Management Plan 2020-2040 Part 4B, Page 3 <br />
