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 separation from the bottom of the system and the <br /> saturated soil. The upgrade requirement is determined by the City of Orono. <br /> This on-site sewage treatment system is designed for a Type 1, four bedroom home, in <br /> accordance with the Minnesota Pollution Contro!Agency Chapter 7080 and local <br /> ordinances. <br /> The soifs on this site are SCS soils mapped - LmB - Lerdal loam. The seasonally <br /> saturated soils were located at 12" to 22" (mottled soif). Due to the seasonally saturated <br /> soils, a Pressurized Mound System will need to be instalted to treat septic efftuent. 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 of 8.5 mpi. <br /> The existing tank or tanks are old and deep and will most likely need to be abandoned, <br /> pumped and filled with soil. <br /> A pumping chamber will need to be instalfed to !ift 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 tight <br /> and sound device, this is in case of a pump failure. <br /> �:-;:�n <br /> 1 <br /> �: . <br /> � . <br />
