Co. , Mn • <br /> , <br /> This system is Designed for a Type 1, four 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 - LrB - Lester � <br /> loam. � seasonally high water table was located at the surface, 6" , <br /> 8" , 12" & 30" , (mottled soil) . This site has been excavated. Assuming <br /> mottled soil at 12" , percolation tests indicate the soil is not <br /> " compacted. This is the ohly area available for On-Site Sewage <br /> treatment. Due to� the seasonally high water table, a pressurized <br /> mound system will need to be installed. The bottom of the rock bed <br /> must be located at least �3 ' above the seasonally high water table. <br /> The soils at a depth of 1.8" have a percolation rate averaging 31.7 <br /> min/inch and are adequate• for treating septic effluent. � <br /> A pumping chamber will ne�ed to be installed to lift the effluent to the <br /> treatment area. <br /> The manifold and supply line pi:pe must have back drainage to the pumping <br /> chamber. The distribution pipes shall have their ends capped. Be sure <br /> the rock and sand fi11 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 ligh� and sound device, this. is in case of a pump failure. <br /> (Mercury floats are a good method) . � <br /> All neighbort.ng wells are located more than 100 ' away from the propo:�:�:9 <br /> treatment area. . � <br /> Keep all heavy equipment off of� the proposed treatment area before and <br /> after construction as much as possible. The treatment area should be <br /> marked off before� construction. <br /> �- , • � , <br /> • � � Soil and Percolation Teata CONT'D <br /> �, � � Septic Syatem Deaign <br />
