. Rusty Olson's--Soil and Percolation Testing Joseph J. Olson--MPCA License #810 11481 Riverview Rd. NE, Hanover, MN 55341 (763) 498-8779 Fax (763) 498-8290 October 13,2002 Capestone Builders 2915 Somerset Lane Orono,Henn.Co. This on-site Sewage Treatment System is designed for a Type 1,six-bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The soils on this site are SCS.mapped-LrB-Lester loam.The seasonaily saturated soils were located at 24"-30" (mottled soil). Due to seasonally saturated soils,a pressurized Mound System will need to be installed to treat septic ef�luent. 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 6 MPI. To reduce the Qallons per minute size of the�unn Use 7/32 inch Rerforations on the laterals All neighboring wells are located greater than 100' away from proposed treatment area. A pumping chamber will need to be installed to lift the ef�luent to the treatment area. The power supply and Switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. A warning device must be installed with light and sound devices;this is in case of a pump failure.The manifold and supply line must have back drainage to the pumping chamber. The distribution pipes shall have their ends capped. Be sure the rock and sand fill materials aze clean. The sod layer below the entire mounded area must be turned over,just break up the sod and be sure not to over work. �ggp all he�vy equioment off of the Rronosed treatment areas before during and after construction. T6e Arpa around both sites must be fenced off by the contractor before any construction be�ins Th�s Des�gn�s not �alid and the System will need to be relocated if failure to protect the areas Rroposed for On-Site Sewaee Treatment occurs. With proper installation and maintenance,this system should have no problem in trcating septic ef�luent effectively. Nothing other than gray water,(laundry,showers,etc.) Human water and toilet tissue should be disposed of into the septic tanks. Garbage disposals are not recommended. Additives must not be used;they may cause harmful damage to your septic system. It is recommended that you pump the tank every year for 1 tank, every two years for two tanks.
