Co., MN ���, ��f �` <br /> These sites have existing on-site sewage treatment systems which are classified as <br /> failed due to not meeting a 3' separation from the saturated soil (mottled soil) and the <br /> bottom of the system. A new system will need to be installed. <br /> This on-site sewage treatment system is designed for a Type 1, six bedroom home <br /> (main) & one bedroom (caretaker) home, in accordance with the Minnesota Pollution <br /> Control Agency Chapter 7080 and local ordinances. <br /> The soils on this site are SCS soils mapped - KkC - Kilkenny loam. The seasonally <br /> saturated soils were located at 16" to 28". Due to the seasonally saturated soils, a <br /> Pressurized Mound System will need to be installed to treat septic effluent. The bottom <br /> 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 averaging 7.9 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 />
