HomeMy WebLinkAbout06-08-1987 - Septic system, 2nd proposal S-P TESTING, INC. 951 KATYDID LANE ST. MICHAEL, MN 55376 497-3566 STEVE SHIRMERS June 8 , 1987 John McDowell Lot 4, Block 1 Woodhill Orono, Henn. Co. , MN. This system is designed for a Type 1, five 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 - HbC - Hayden loam. A seasonally high water table was located at 56" to 64" , (mottling) . The bottom of each trench must be located at least 3 ' above the seasonally high water table. The soils at a depth of 24" have a percolation rate averaging 24.0 min/inch and are adequate for a standard treatment system. A pumping chamber will need to be installed to lift the effluen to the treatment area. The power supply and switches must be located outside the manhole and pump- ing chamber in a weather proof enclosure. A warning device must be in- stalled with a light and sound device, this is in case of a pump failure. (Mercury floats are a good method) . The supply line pipe must have back drainage to the pumping chamber. 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 much as possible. The treatment area should be marked off before construction. With proper installation and maintenance, this system should have no prob- lem in treating septic effluent effectively. It is recommended that the septic tanks be pumped every 2 years. Steven B.
