D. 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 ca ty 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 lakf ore residential areas. The original 6 projects were inct.. led from 1964 through 1979. The following additions and upgrades have occured from 1980 to 1992: 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/Norther n Avenue - sewer laterals connecting to existing lift station - 1982 approximately 35 residential connections - Included lift station #6 bypass. 4. Carman Street Project (private) - 1984 - lift station and laterals - 3 residential units.
