Co. , MN <br /> This system is Designed for a Type 1, three bedroom home and in accordance <br /> with the Minnesota Pollution Control Agency Chapter 7080 and local <br /> ordinances . • __ <br /> The soils on this site are typical of SCS soils mapped - ErC2 - Erin <br /> clay loam bordered by - Ha - Hamel loam. A seasonally high wate•r <br /> table was located at 18" , 26" & 32" , (mottled soil) . Due to tYte <br /> seasonally high water table, a Pressurized Mound System will need to <br /> be installed. The bottom of the rock bed must be loc:ated at least <br /> 3 ' above the seasonally high water table. Due to the System beiilg <br /> located at the base of a slope & possible drainage from the east, an <br /> Interceptor Drain will need to be installed South & East. <br /> The soils at a depth of 12" have a percolation rate averaging 4. 2 <br /> min/inch. <br /> An Interceptor Drain will need to be installed at a minimum depth of 4 ' <br /> below the bottom of the lower trench with a maximum of 4 trenches . Also <br /> a 10 ` horizontal distance between the trench and Interceptor Drain. The <br /> Interceptor Drain should have a minimum of 24" of poris material above <br /> the drain tile (if sand or gravel- is used, the tile should bP wrapped <br /> with filter cloth) . <br /> A pumping chamber will need to be installed to lift the effluent to the <br /> treatment area. � <br /> The manifold and supply line pipe must have back �rainage to the pumping <br /> chamber. The distribution piges shall have their ends capped. Be sure <br /> the rock and sand fill material are clean. The sod layer below the <br /> entire mounded area must be turned over, just break up the sod, be sure <br /> not to over work. <br /> CONT'I� • <br /> b • <br /> Soil and Percolation Tests <br /> Sep�ic Syslem Design <br />
