Co., MN <br /> This site has an existing on-site sewage treatment system which is classified as failed <br /> due to not meeting the required 2' separation from the bottom of the system and the <br /> saturated 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 a clay loam. The seasonally saturated soils were located at 22" to <br /> 30" (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound System <br /> will need to be installed to treat septic effluent. The bottom of the treatment area must <br /> be located at least 3' above the saturated soils. <br /> The soils at a depth of 12" have a percolation rate of 18.5 mpi. In the area of test hole <br /> #2, approximately 4" of fill soil was found. The percolation test did not indicate <br /> compaction. This soil should be removed using a backhoe, see site plan for area <br /> needing removal. <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 waming device must be installed with a light <br /> and sound device, this is in case of a pump failure. <br /> 1 <br />
