Lot 2, Block 1 Orono, Henn. Co., MN November 15, 1995 This On-Site Sewage Treatment System is Designed for a Type 1, five bedroom home Designed in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The soils on this site are a clay loam. The seasonally saturated soils were located at 20" to 28" (mottled soil) below the ground surface. Due to the saturated soils, a Pressurized Mound System will need to be installed to treat septic effluent. The soils at a depth of 12" have a percolation rate averaging 9.8 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 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. (mer All neighboring wells are located greater than 100' away from the proposed treatment area. 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. CONT'D J With proper installation and maintenance, this system should have no problem i~ treating septic effluent effectively. Nothing other than gray water (laundry, showers, etc.) human waste & toilet tissue should be disposed into the septic tanks. Garbage disposals are not recommended. 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 tank through the manhole by a certified-pumper every year if you have 1 tank and every 2 years if you have two tanks. ~~~-~ Steven B.
