NE,Hanover, MN 55341 <br /> (612)498-8779 <br /> November 12, 1998 <br /> Robert&Stephanie Jochims <br /> 485 Stubbs Bay Road <br /> Orono,Henn.Co. <br /> This On-Site Sewage Treatment System is Designed for a Type 1, four bedroom home in accordance with the <br /> Minnesota Pollution Control Agency Chapter 7080 and local ordinances. <br /> The soils on this site are SCS soils mapped - LRB-Lester Loam. The seasonally saturated soils were tocated at <br /> 16"-20"(mottled soil). Due to the seasonaily saturated soils, a pressurized mound system will need to be installed <br /> to treat septic efFluent. The bottom of the treatment area must be located at least 3' above tbe saturated soils. <br /> Test 6ole#1 slow some mottling frnm 0"-10"due to piow layer,but it disappears. <br /> The soits at a depth of 12"have a percolat'ron rate averaging 9 MPL <br /> Eaisitng tanks may be ased upon approval of local iaspector. <br /> A variance will be needed to be closer than 20' to property line. <br /> A pumping chamber will need to be installed to lift the etlluent to the treatment area. The power supply and <br /> switches must be located outaide the manhole and pumping chamber in a weather proof enciosure. A warning <br /> device must be installed with light and sound device,this is in case of a pump failure. <br /> The manifold and supply line pipe must have back drainage to the pumping c6amber. The distribution pipes shall <br /> have their ends capped. Be sure the rock and sand fitl materials are clean. The sod layer below the entire <br /> mounded area mast be turned over,just break up the sod,be sare not to over work. <br /> Keep all heavy equipment off ot the proposed treatment arexs before and after construction. The treatment area <br /> should be marked off before construction. This Design is not valid& the System will need to be relocated if failure <br /> to prntect the areas proposed for On-Site Sewage Treatment occurs. <br /> Nothing other than gray water,(laundry,showers,etc.)6uman waste& toilet tissue should be disposed of into the <br /> septic tanks. Garbage disposals are not recommended. Additives must not be used, they may cause harmful <br /> damage to your septic system. It is recommended that you pump the tank every year for 1 tank every two years <br /> for two tanks. <br /> Sincerely, <br /> Joseph J.Olson <br /> / <br /> j��r��� <br /> i <br />
