Co., MN <br /> This on-site sewage treatment system is designed for a Type 1, five bedroom home, in <br /> accordance with the Minnesota Pollution Control Agency Chapter 7080 and local <br /> ordinances. <br /> The soils on this site are a clay loam. The seasonally saturated soils were located at <br /> 18" to 38" (mottled soil). Due to the seasonatly saturated soils, a Pressurized Mound <br /> System will need to be installed to treat septic effluent. The bottom of the rock must be <br /> located at least 3' above the saturated soils. <br /> The soils at a depth of 12" have a percolation rate of 12.6 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 befow the entire mounded area must be turned over, <br /> just break up the sod, be sure not to over work. <br /> All neighboring wells are located greater than 100' away from the proposed treatment <br /> area. <br /> 1 <br />
