CITY of ORONO <br />Post Office Box 66aCrystal Bay, Minnesota 55U3•Municipa, Offices <br />On the North Shore of Lake Minnetonka <br />February 14, 1986 <br />James C. Tong <br />1603 Black Oaks Place <br />Plymouth, MN 55447 <br />Re: Request to occupy residence prior to completion of <br />drainfield. <br />Dear Mr. Long: <br />This letter grants you permissior to occupy your new <br />residence at 765 Dickey Lake Drive prior to installation of the <br />sewage treatment mound portion of your septic system subject to <br />the following: <br />1. Installation of tanks must be complete prior to <br />occupancy, <br />2. Tanks shall be pumped out by a licensed pumping <br />contractor as oFten as r.:cessary to eliminate any sewage <br />discharge to the ground surface, <br />3. Mound system installation shall be completed no later <br />than July 15, 1986, <br />4. Final mound system location must be approved by City <br />Inspector, <br />5. No occupancy pri(,r to issuance of Temporary <br />Certification of Occupancy by Building & Zoning Department <br />Jim, you mentioned in your letter of request that a sewage <br />ejector will be used. I presume that the intent is to gravity - <br />flow the upper floors and eject just the basement sewage to the <br />tanks. You realize that an effluent pump is needed in the 3-d <br />septic tank compartment for pressure distribution throughout the <br />Tound. The sewage ejector in t_he basement will not reduce the <br />ovp-all volume of material in the tanks, especially since over <br />95% of your household waste is water. The ejector will likely <br />(,nly break down the sewage solids into smaller pieces while not <br />reducing the volume. <br />WILOING&.
