Schirmers 951 Katydid Lane NE • St. Michael, MN 55376 • (612) 497-3566 FAX (612)-497-5011 State License#394 � � September 27, 1998 Christine Bruce 2205 Abingdon Way Orono, Henn. Co., MN A future expansion site wa� evaluated for this property. The design will need to be completed prior to insta�lation. The soils on this site are SCS soils mapped - Lr6 - Lester loam. The seasonally saturated soils were located at 24" to 36" (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound System will need to be installed to treat septic effluent. The bottom of the treatment area must be located at least 3' above the saturated soils. The soils at a depth of 12" have a percolation rate averaging 3.0 mpi. A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and switches must be located outside the manhole and pumping chamber in a weather proof enclosure. A waming device must be installed with a light and sound device, this is in case of a pump failure. 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 tayer below the entire mounded area must be tumed over, just break up the sod, be sure not to over work. All neighboring wells are located greater than 100' away from the proposed treatment area. ' 1 • " C � Keep all heavy equipment off of the proposed treatment areas before and after construction. The treatment area should be marked off before construction. This Design is not valid 8�the system wili 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 human waste, toilet tissue, laundry, showers, water softener etc. should be disposed of into the septic tanks. Iron filters must be diverted out of the system. Garbage disposals are not recommended, due to adding more solids &fine solids passing through to the system. Excessive amounts of soaps, cleaning agents & chlorine agents may kill the bacteria needed to treat septic effiuent. Additives are not recommended. Recommend to pump & clean your tanks through the manhole by a certified pumper every 2 years. Check with your pumper to set up a schedule. � Steven B.
