Co., MN <br />This site has an e)dsting on-site sewage treatment system classified as failed. The <br />system is surtace discharging which is classified as an imminent health hazard under <br />Minnesota Chapter 7080 rules which must be repaired or disconnected within 10 <br />months. This v^il need to be verified with the cHy. <br />This on-site sewage treatment system is designed for a Type 1. three bedroom home, in <br />accordance with the Minnesota Pollution Control Agency Chapter 7080 and local <br />ordinances. The area available will support a five bedroom home for a sub-division. <br />Approval will be needed from the city to be 10' away h-om the house with the tanks and <br />55' away from the well with the tanks. <br />e <br />The soils on this site are SCS soils mapped - KkB - Kilkenny loam. The seasonally <br />saturated soils were located at 12" to 24" (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 averaging 4.2 mpl. <br />A lift pump will be needed in the lower level for the floor drains. <br />The existing tank is most likely not water tight and will need to be abandoned, pumped <br />and filled with soil. <br />1
