Co., MN <br /> This site has an existing on-site sewage treatment system classified as failed due to not <br /> meeting the 2' separation from the bottom of the system and the saturated soil. The <br /> system is approximately 3' deep with the saturated soil at 24" to 30" deep. To <br /> adequately treat septic effluent, a new system will need to be installed. <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 property lines must be verified prior to installation of the system. <br /> The soils on this site are SCS soils mapped - HcB2 - Hayden clay loam. The seasonally <br /> saturated soils were located at 18" to 26" (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 17.8 mpi. <br /> . . , <br /> The existing tank may be used upon approval from the local Inspector. The tank must <br /> be water tight, if not abandon, pump &fill with soil. <br /> 1 <br />
