Co., MN <br /> This On-Site Sewage Treatment System is Designed for a Type 111, three bedroom <br /> home (218 gal/day), in accordance with the Minnesota Pollution Control Agency Chapter <br /> 7080 and local ordinances. <br /> The soils on this site are SCS soils mapped - HbC - Hayden loam. The seasonally <br /> saturated soils were located at 66" & 70" (mottled soil) . The bottom of the treatment <br /> area must be located at least 3' above the seasonally saturated soils. A standard trench <br /> system may be installed. The plumbing will need to be changed to exit the cabin to the <br /> south. The existing tank off of the northeast comer of the cabin wilt need to be <br /> abandoned, pumped and filled with soil. A new 1000 gallon and a 500 gallon tank will <br /> need to be installed. Insulate all the tanks to prevent freezing. The tanks will be plastic, <br /> so use spray polyurethane which will insulate and add strength to the tanks. <br /> The soils at a depth of 3�" have a percolation rate averaging 37.3 mpi. <br /> All neighboring wells are located greater than 75' away from the proposed treatment <br /> area to the south and 100' away to the north. <br /> Keep all heavy equipment off of the proposed treatment area before and after <br /> construction. The treatment area should be marked off before construction. This <br /> Design is not valid & the system will need to be relocated if failure to protect the areas <br /> proposed for On-Site Sewage Treatment occurs. <br /> 1 <br />
