Co., MN <br />/ / <br />;>■ <br />//£ § <br />This On-Site Sewage Treatment System is Designed for a Type l,Five <br />bedroom home in accordance with the Minnesota Pollution Control <br />Agency Chapter 7080 and local ordinances. <br />-4M <br />The soils on this sits are SCS soils mapped - LmB - Lerdal loam. <br />A seasonally high water table was located at 14" to 24", (mottled <br />soil). Due to the seasonally high water table, a Pressurized <br />mound System will need to be installed. The bottom of the roclc <br />bed must be located at least 3' above the seasonally high water table. <br />The soils at a depth of 12" have a percolation rate averaging 13.8 <br />min/inch and are adequate for treating septic effluent. <br />-•ii <br />A pumping chamber will need to be i.nstalled to lift the effluent to the <br />treatment area. <br />The manifold and supply line pipe must have back drainage to the pumping <br />chamber. The distribution pipes 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 />The power supply and switches must be located outside the manhole and <br />pumping chamber in a weather proof enclosure. A warning device must be <br />installed with a light and sound device, this is in case of a pump failure. <br />(Mercury floats are a good method). <br />All neighboring wells are located greater than 100' away from th*^ <br />roposed treatment area. <br />-i; <br />mmrn <br />CONT* D <br />mmmkmmm <br />.:'y m <br />■4\. i . . . -i ■''n- ■'V
