B. The completion of the Maple Plain interceptor in 1984 removed the last of 7 municipal sewage treatment plant discharges into Lake Minnetonka. The City of Orono had originally opposed construction of this interceptor in favor of treatment plant upgrades, because the excess capacity of the interceptor would be counterproductive to Orono ’s plans for rural, low density development. As a result of Orono's opposition to the excess capacity, the Maple Plain interceptor was redesigned and constructed at a size which provides no capacity for use by Orono (M.W.C.C. Project #83~52). C. An upgrade of the Orono/Minnetonka Beach Interceptor was completed in 1989, resulting in additional capacity* Prior to this project, peak capacities had been exceeded on a number of occasions, allowing untreated sewage to overflow into Lake Minnetonka (M.W.C.C. Project #85-67). 2. Municipal Facilities. The City of Orono continues to operate a municipal system of sewer trunks and laterals in various non-contiguous sections of the City. This non-contiguity results from, a number of sewer projects serving pockets of historically dense development. These sections are broken down as follows: A. SOUTHWEST ORONO SYSTEM. This system serves the Navarre business area as well as the majority of Orono's lakeshore residential areas. The original 6 projects were installed from 1964 through 1979 The following additions and upgrades have occured from 1980 to 1990: 1. North Shore Drive/Scotch Pine - sewer laterals and lift station - 1980? 12 residential connections. 2. North Shore Drive/Highwood - sewer laterals - 1981- 3 residential connections, plus 3 stubs for future use. 3* Navarre Theater Project/Northern Avenue - sewer laterals connecting to existing lift station - 1982 - approximately 35 residential connections - included lift station #6 bypass.
