Co., MN Requirements including items not specifically noted in this review. <br /> KEEP THIS PLAN SET ON SITE AT ALL TIMES <br /> The existing on-site sewage treatment system is located in the construction limits for <br /> the State Highway 12 project and will be abandoned. The existing tanks will be <br /> pumped and filled with soil or removed. <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 24" (mottled soil). Due to the seasonally 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 30.0 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 /> 1 <br />
