The proposal is to move the house to the East of the lot as shown on the <br /> site plan. The existing tanks will need to be abandoned, pumped and filled with soil. <br /> This on-site sewage treatment system is designed for a Type 1, four bedroom home, in <br /> accordance with the Minnesota Pollution Control Agency Chapter 7080 and local <br /> ordinances. <br /> The soils on this site are SCS soils mapped - KkB - Kilkenny loam. The seasonally <br /> saturated soils were located at 16" to 26" (mottled soil). Due to the seasonally saturated <br /> soils, a Pressurized Mound System will need to be installed to treat septic effluent. The <br /> bottom of the treatment area must be located at least 3' above the saturated soils. <br /> The soils at a depth of 12" have a percolation rate of 9.5 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 /> • <br /> • <br /> 1 <br />
