Co. , MN. • • This system is designed for a Type 1, four bedroom home and in accordance with the Minnesota Pollution Control Agency standards WPC 40 and local ordinances. The soils on this site. are typical of SCS soils mapped - LrB - Lester loam. A seasonally high water table was located at 16" , 20" , & 24" , (mottling) . Due to the seasonally high water table, a pressurized mound system will need to be installed. The bottom of the rock bed must be located at least 3 ' above the seasonally high water table. The soils at a depth of 18" have a percolation rate averaging 10 . 4 min/inch and are adequate for treating septic effluent. A pumping chamber Will need to be installed to lift the effluent to the treatment area. The manifold and supply line pipe must have back drainage to the pumping chamber. The distribution pipes shall have their ends capped. Be sure the rock and sand fill material are clean. The sod layer below the entire mounded area must be turned over, just break up the sod, be sure not to over work. , The power supply and switches must be located outside the manhole and pumping chamber in 'a weather proof enclosure. A warning device must be installed with a light and sound device, this is in case of a pump failure. (Mercury floats are a good method) . All neighboring wells are :located more than 100 ' away from the proposed treatment area. • Keep all heavy equipment Off of the proposed treatment area before and after construction as' mucI as possible. The treatment area should be marked off before construction. With proper installation and maintenance, this system should have no problem in treating septiq effluent effectively. It is recommended that the septic tanks be pumped every 2 years . (53 Soil and Percolation Tests 57;A)---- Steven B.
