:5_p TESTING, INC. Steven B. Schirmers -MPCA Cert. No. 627 <br />951 Katydid Lane NE • St. Michael, MN 55376 • (612) 497-3566 <br />Dennis Platteter <br />809 No.Brown Rd. <br />Lot 2, Block 1 <br />Orono, Henn. Co., MN <br />November 15, 1995 <br />This On-Site Sewage Treatment System is Designed for a Type 1, five <br />bedroom home Designed in accordance with the Minnesota Pollution <br />Control Agency Chapter 7080 and local ordinances. <br />The soils on this site are a clay loam. The seasonally saturated <br />soils were located at 20" to 28" (mottled soil) below the ground <br />surface. Due to the saturated soils, a Pressurized Mound System <br />will need to be installed to treat septic effluent. <br />The soils at a depth of 12" have a percolation rate averaging <br />9.8 min/inch. <br />A pumping chamber will need to be installed to lift the effluent <br />to the treatment area. <br />The manifold and supply line pipe must have back drainage to the <br />pumping chamber. The distribution pipes shall have their ends <br />capped. Be sure the rock and sand fill material are clean. The <br />sod layer below the entire mounded area must be turned over, just <br />break up the sod, be sure not to over work. <br />The power supply and switches must be located outside the manhole <br />and pumping chamber in a weather proof enclosure. A warning device <br />must be installed with a light and sound device, this is in case of <br />a pump failure. (mer <br />All neighboring wells are located greater than 100' away from <br />the proposed treatment area. <br />Keep all heavy equipment off of the proposed treatment area before <br />and after construction. The treatment area should be marked off <br />before construction. This Design is not valid & the system will <br />need to be relocated if failure to protect the areas proposed <br />for On-Site Sewage Treatment occurs. <br />CONT'D <br />J
