. ._,4`r. .t: r CITYof ORONO Pat Office Bm Ga•CryWI Bay, Miaaauufa &"Ve Munfaaal COMM It On the North Shore of Lake Minnetonka December 5, 1985 Mr. Glenn Cook BOnestroo, Ro:ene 2335 W. Trunk Hwy 36 St. Paul, MN 55113 Re: MACC Project 86-S1/Orono Interceptor Improvements Dear Glenn, Having reviewed the intent of the project referenced above together with your proposal the selection of Boneattoo as the engineer on the project would be of benefit to Orono in many ways, as it would bring to bear your experience with the Orono system together with the desires and needs of Orono for improvements including the proposed telemetry system. There is however, two areas of concern, in that the improvements may entail the replacement of existing forcem3in piping, which was originally put in as part of the original Orono sewer system. Being fully cognizant of the fact that there are time, that the system has overflowed causing sewage to flow both into basements ane also raw sewage into Lake Minnetonka, there is very possibly the need beyond lift station improvements to handle the current capacity in the lines. While it may be appropriate that the size of the pipe could or should be Chang-d, I do see a potential conflict in two regards as they relate to Bonestroo being both City Engineer and also the selected Engineer on behalf of MWCC for those improvements. They are as follows: To the extent that there is needed a decision or recommendation regarding replacement of the pipe that the interests of Orono and MWCC may be in coot 14et as to whether changes in lift stations and telemetry v uld alleviate the problem at a lesser cost than actual replacement of the pipe or if both are needed in order to accomplixh alleviation of existing problems. b. To the extent a recommendation needs to be made regarding the sizing of the pipe there could be a difference as to the size based on the divergent goals betwern MWCC and Orono. ale LMbr:arfplwf:-O)+19r • enwrrmn anenaflVanrl-xfLr wa • fl'tl rfraaU -ONW aarestwa:
