Rusty Olson's--Soil and Percolation Testing Joseph J. Olson--MICA License#810 11481 Riverview Rd. NE, Hanover, MN 55341 (763)498-8779 Fax(763)498-8290 April 29, gs„ — 11%9 —c 5 AA)" Vu�S�7`' "/S Mike Schultelte 4640 West Branch Road d 44Z-4-- Orono,Henn.Co. This on-site Sewage Treatment System is designed for a Type 1. four bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The soils on this site are SCS soils mapped-KkB-Kilkenny Loam.The seasonally saturated soils were located at 14"-20"(mottled soil). Due to seasonally saturated soils,a pressurized Mound System will need to be installed to treat septic effluent. The bottom of the treatment area must he located at least 3' above the saturated soils. The soils at a depth of 12"have a percolation rate averaging 10 MPI. All neighboring wells are located greater than 100' away from proposed treatment area • The existing tank must be abandoned. The existing system does not conform to chapter 7080. 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 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 are 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. Keep all heavy equipment off of the proposed treatment area before during and after construction. This Design is not valid and the System will need to be relocated if failure to protect the area 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 water and toilet tissue should he 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 I tank every two years for two tanks.
