Co., MN <br /> This on-Site Sewage Treatment System is Designed for a Type 1, five bedroom home <br /> designed in accordance with the Minnesota Pollution Control Agency Chapter 7080 and <br /> local ordinances. <br /> The soils on this site are SCS soils mapped - KIC2 - Kilkenny clay loam. The seasonally <br /> saturated soils were located at 6" to 18" (mottled soil). Additional Soil Borings were <br /> completed west of Boring #1 &#S which show mottled soil at 12" 8� 16" (shown on site <br /> plan). Due to the seasonally saturated soils, a Pressurized Mound System will need to <br /> be instalted to treat septic effluent. The bottom of the treatment area must be located at <br /> least 3' above the saturated soils. <br /> The soils at a depth of 12" have a percolation rate averaging 5.3 mpi. <br /> A pumping chamber will need to be installed to lift the effluent to the treatment area. <br /> The power supply and switches must be located outside the manhole and pumping <br /> chamber in a weather proof enclosure. A warning device must be installed with a light <br /> 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 chamber. <br /> The distribution pipes shall have their ends capped. Be sure the rock and sand fill <br /> material are clean. The sod layer below the entire mounded area must be turned over, <br /> just break up the sod, be sure not to over work. <br /> 1 <br />
