S -P TZ STING, INC. <br />951 KATYDID LANE <br />ST. MICHAEL, MN 55376 <br />4973566 <br />STEVE SHIRMERS <br />October 31, 1906 <br />Rick Stueland <br />4080 Bayside Rd. (Co.Rd.84) <br />Orono, ::enn. Co., MY. <br />This system is designed for a Type 1, three bedrrom home and in accordance <br />with the Minnesota Pollution Control Agency standards MPC 40 and local <br />ordinances. <br />The soils cn this site are typical of SCS .oils mapped - KkC - Kilkenny <br />loam s Erin Roils. A seasonally high wafer table was located at 18" i 240, <br />(mott'inq). Lz^ — the seasonally high water table, a pressurized mound <br />system will need to be installed. The bottom of the rock bed must be lo- <br />cated at least 3' above the seasonally high water table. <br />This site has a holding tank or tanks, which overflows to the surface. This <br />tank or tanks must be abandoned, pump & fill with soil. Two new tanks will <br />need to be inr.talled. <br />The soils at a depth of 18" have d percolation rate averaging 8.2 min/inch <br />and are adequate for treating septic effluent. <br />A pumping chamber will need to be installed to lift the effluent to the <br />mound system. <br />The manifold and supply line pipe must have back drainage to the pumping <br />chamber. The distribution pipes shall have their ends capped. Be sure the <br />rock and sand fill material are clean. The sod layer below the entire <br />mounded area must be turned over, just break up the sod, be sure not to <br />over work. <br />The power supply and switches must be located outside the manhole and pump- <br />ing chamber in a weather proof enclosure. A warning device must be in- <br />stalled with a light and sound device, this is in case of a pump failure. <br />(Mercury floats are a good method). <br />All neighboring well-- are located more than 100 ' away from the proposed <br />treatment area and 50' away from the tanks. <br />Keep all heavy equipment off of the proposed treatment area before and <br />after construction as mach as possible. The treatment area should be <br />marked off before cons' -ruction. <br />With proper installation and maintenance, this system should have no prob- <br />lem in treating septic effluent effectively. <br />It is recommended that the septic tanks be pumped <br />every 2 years.
