Co., MN <br /> This site has an existing on-site sewage treatment system oonsisting of a cesspool & <br /> seepage pits and a small drainfield. The existing system is classified as failed under <br /> Minnesota Chapter 7080 rules. <br /> An addition is proposed for the existing house. This on-site sewage treatment system is <br /> designed for a Type 1, three bedroom home, in accordance with the Minnesota Pollution <br /> Control Agency Chapter 7080 and local ordinances. <br /> Approval wilt be needed from the City to be 10' from the North property line. This <br /> property line should be located prior to installation. <br /> The drainage pipe from the catch basin must be extended to outlet west of the mound. <br /> The pipe must be water tight and follow the north property line. <br /> The existing tanks will need to be abandoned, pumped and filled with soil. The new <br /> supply line will exit the house through the new addition. The existing supply line will <br /> need to be capped. <br /> The soils on this site are SCS soils mapped - LrC - lester loam. The seasonally <br /> saturated soils were located at 38" &42" (redox features). Due to the seasonally <br /> saturated soils, a Pressurized Mound System will need to be instatled to treat septic <br /> effluent. The bottom of the rock must be located at teast 3' above the saturated soils. <br /> 1 <br />
