S-P TES TING� 1 NC. Steven B. Schirmers & Debra M. Schirmers <br /> 951 Katydid Lane NE • St. Michael, MN 5537C (612) 497-3566 <br /> FAX (612) 497-5011 <br /> State License #394 <br /> August 10, 1998 <br /> Bill Yaeger <br /> Lot 64 & 65 <br /> Morse Island Park, Big Island <br /> Orono, Henn. Co., MN <br /> This On-Site Sewage Treatment System is Designed for a Type 111, two bedroom cabin <br /> (180 gal/day), in accordance with the Minnesota Pollution Control Agency Chapter 7080 <br /> and local ordinances. Due to the limited space & no basement below the cabin, a 10' <br /> setback is requested for the tanks from the structure. <br /> The soils on this site are SCS soils mapped - HbC - Hayden loam. The seasonally <br /> saturated soils were located at 60 tq 76 (mottled soil) . The bottom of the treatment <br /> ,� <br /> area must be located at least 3' above the seasonally saturated soils. A standard <br /> gravelless trench system may be installed with a distribution box. <br /> The soils at a depth of 24" & 30" have a percolation rate averaging 31.1 mpi. <br /> A 500 gallon pumping chamber will need to be installed to lift the septic effluent to the <br /> treatment area. The power supply and switches must be located outside the manhole <br /> and pumping chamber in a weather proof enclosure. A waming device must be installed <br /> with a light and sound device, this is in case of a pump failure. <br /> The holding tanks will be 1-500 gallon & 1-1000 gallon. Insulate all the tanks to prevent <br /> freezing. The tanks will be plastic so use spray polyurethane which will insulate and add <br /> strength. <br /> 1 <br />
