Telephone 473.7357 <br />CITY of ORONO <br />Post Office Box 66oCrystal Bay, Minnesota 55323•Municipal Offices <br />On the North Shore of Lake Minnetonka <br />May 7, 1980 <br />James L. Stott, Jr. <br />1850 Fox Ridge Road <br />Long Lake, MN 55356 <br />Dear Mr. Stott: <br />I have reviewed your septic system situation with Ed Sullivan <br />of Sullivan's Services and with Frank Coolbroth who holds the <br />patent on the sewage -osmosis treatment system. I have also <br />contacted Elmer Peterson of Spring Park who has pumped your <br />septic tanks in the past. Mr. Peterson tells me that when he <br />was last out he pumped both tanks and cleaned the line between <br />them. He thinks there is no distribution box in the drain - <br />field and that the tanks need new baffles. <br />Mr. Sullivan called me in to review your problem after finding <br />little or no area for replacement of your existing drainfield. <br />We met on the site and came to no real conclusion. I contacted <br />Mr. Coolbroth specifically to find out whether the sewage <br />osmosis system was an alternative for your lot, and upon insp- <br />ection of the site, he believes it is. <br />Below I have listed what I feel are sume possible options for <br />your lot, listed in order from best to worst in terms of <br />feasibility and chance for successful and convenient operation: <br />1) Obtain an easement or purchase land from neighbor to the <br />south. Would possibly require a lot line rearrangement. <br />Install new drainfield in natural soils in this area. <br />2) Retrofit Ath an osmosis -type system as per Frank Coolbroth <br />design. Would require pump to higher ground east of drive- <br />way. I consider this an alternative which is in an exper- <br />imental stage (few existing installations over 10 years old) <br />but would allow it on your site. <br />
