Schirmers • MPCA Cert.No. 627 951 Katydid Lane NE • St. Michael, MN 55376 • (612) 497-3566 FAX (612)-497-5011 State License #394 December 21, 1996 Fullerton Lot 2, Fullerton Estates Fox Street 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 site are SCS soils mapped - HbB - Hayden loam. The seasonally saturated soils were located at 12" to 40" (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 7.8 mpi. A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supp{y 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. 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. All neighboring wells are located greater than 100' away from the proposed treatment area. 1 . t i Keep al! heavy equipment off of the proposed treatment area before and after construction. The treatment area shouid 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 effectiveiy. 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, 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 effluent. 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. C11"'--- �• Steven B.
