Joseph Olson _D.B.A. <br />Rusty Olson's--Soil and Percolation Testing <br />Joseph J. Olson--MPCA License #810 <br />11481 Riverview Rd. NE, Hanover, MN 55341 <br />September 23, 2014 <br />Peter Rennebohm <br />Proposed lot 1 <br />4565 Bayside Road <br />Orono, Hennepin County <br />(763) 498-8779 fax (763) 498-8290 <br />This on-site Sewage Treatment System is partially designed for a Type 1, five-bedroom home in <br />accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. <br />Once the house size, location and sep tic prim ary and future s~es are chosen this design can be completed. <br />¢ <br />The periodically saturated soils were located at 12-18 Inches (mottled soil). Due to the periodically <br />saturated soils, a pressurized mound system will need to be installed to treat the septic effluent. The bottom <br />of the treatment area must be located at least 3' above the saturated soils. <br />The soils at a depth of 12" have a percolation rate averaging 8.0 MPI. <br />A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and <br />switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. A <br />warning device must be installed with a light and sound device; this is in case of a pump failure. <br />Use 7/32 inch perforations on the laterals. <br />Keep all heavy equipment off of the proposed treatment areas before and after construction. The <br />treatment area must be fenced off before construction begins. This Design is not valid & the System <br />will need to be relocated if failure to protect the areas proposed for the On-Site Sewage Treatment <br />systems occurs. <br />Nothing other than gray water, (laundry, showers, act.) human water & toilet tissue should be disposed of <br />into the septic tanks. Garbage disposals are not recommended. Additives must not be used; they may cause <br />harmful qamage to your septic system. It is recommended that you pump the septic tank s every two years. <br />REeetV~D <br />SEP242014 <br />CITY OF ORONO
