CMP Part 4B. Sanitary Sewer Plan City of Orono Community Management Plan 2020-2040 Part 4B, Page 4 (LS-59). The system was constructed with eighteen projects from 1964 to 2007. This is the original municipal sewer system and it still serves the majority of urban Orono. These lines were installed to provide pollution abatement and sewer service to the Navarre business area and to the urban residential areas along Lake Minnetonka. The downstream interceptors system consists of all trunk and lateral lines which directly discharge to the Orono-Long Lake Interceptor (MCES 7113 and 7113A) downstream from L.S. 59 but upstream of Meter # 435. These direct discharges are via City-owned and maintained lift stations pumping into the MCES force main at a limited number of locations. Construction occurred during 1980-2014. 2. Highway 12 Area System (MCES metershed M431): This system consists of all lines which are upstream from and ultimately discharge to LS-60. Construction consisted of sixteen Projects from 1967 to 2018. This portion of the municipal system was initially constructed as an extension of the Long Lake municipal system primarily to provide sewer (and water) service to the Orono High School. This system currently serves all of the urban and commercial area in the North West portion of the city along the County Road 6 and 112 corridor. 3. Long Lake Connections.

Lift Stations. The Orono Sanitary Sewer system is serviced by 44 Lift Stations, listed on Table 4B-1: Lift Stations. 7. Agreements with Adjacent Cities.
