S.P TESTING, INC. <br />961 KATYDID LANE <br />ST. MICHAEL, MN 55376 <br />497.3566 <br />STEVE SHIRMERS <br />November 10, 1987 <br />Tom Betz <br />Lot 3 of lot 41 <br />Auditor's Sub #203 <br />Stubbs Bay Road <br />Orono, Henn. Co., MN <br />This system is designed for a Type 1, four bedroom home and in accordance <br />with the Minnesota Pollution Control Agency standards WPC 40 and local <br />ordinances. <br />The soils on this site are typical of SCS soils mapped - :.+B - LeSueur loam. <br />A seasonally high water table was located at 16", 20", 22", 26", 5 280, <br />(mottling). Due to the seasonally high water table, a pre3surized mound <br />system will need to be installed. The bottom of the rock Iced must be lo- <br />cated at least 3' above the seasonally high water table. <br />The soils at a depth of 1B" have rzr^olation La`e aver%ying 6.1 min/inch <br />and are adequate for treating septic effi.-jnt. <br />A pumping chamber will need to be i.1stalled to lift the: `fluent to tt..? <br />treatment area. <br />The manifold and supply line pipe must ha -v:- uac:K drainage to the pumping <br />chamber. The distribution pipes shall hav,s their ends capped. Be sure <br />the rock and sand fill material are c ea,-. The sod layer below the <br />entire mounded area must be turned over, just break up the sod, be sure <br />not to over work. <br />The power supply and switches must be located outside the manhole and <br />pumping chamber in a weather proof enclosure. A warning device must be <br />installed with a light and sound device, this is in case of a pump failure. <br />(Mercury floats are a good method). <br />All neighboring wells are located more than 100' away from the proposed <br />treatment area. <br />Keep all heavy equipment off of the proposed treatment area before and <br />after construction as much as possible. The treatment area should be <br />marked off before construction. <br />With proper installation and maintenance, this system should have no <br />problem.in treating septic effluent effectively. <br />It is recommended that the septic tanks be pumped evr-r7 2 years. <br />Soil and PercoMtiow To.a��_ 1�iL� �_ _ <br />Septic System D filln Steven B.
