No. 627 951 Katydid Lane NE * St. Michael, MN 65376 • (612) 497-3566 December 13, 1993 Coffin site Lot 8, Block 1 Orono, Henn. Co., MN This On -Site Sewage Treatment System is Designed for a Type 1, five bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The soils on this -A-*-_* are SCS soils :napped - KkB - Kilkenny loam & LrB - Lester loaff. A seasonally high water table was located at 24" to 30", (mottled soil). 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 12" have a percolation rate averaging 5.9 min/inch. 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 distributir.)n 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 greater than 100' away from the proposed treatment area. CONT'D Coffin site Lot 8, Block 1 Orono, Henn. Co., MN (2) Keep all heavy equipment off of the proposed treatment area before and after construction. The treatment area should be marked off before construction. This Design is not valid & the System will need to be relocated if failure to protect the areas proposed for On -Site Sewage Treatment occurs. With proper installation and maintenance, this system should have no problem in treating septic effluent effectively. Nothing other than gray water, (laundry, showers, etc.) human waste & toilet tissue should be disposed of into the septic tanks. Garbage disposals are not recommended. Smaller amounts of laundry soaps, dish soaps, cleaning agents, etc. are better for the system. Antibacterial soaps & chlorine agents may kill the bacteria needed to treat septic effluent properly Additives are not recommended, they may cause harmful damage to your system. Recommend to pump & clean your tanks by a certified pumper every year if you have 1 tank & every 2 years if you have 2 tanks to insure proper maintenance. Steven R. Schirmers, SBS/ds c.: t y.
