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 />(763) 498-8779 Fax (763) 498-8290 <br />July 21, 2018 <br />Gordon James <br />225 Old Crystal Bay Load S. <br />Orono, Hennepin County <br />This on-site Sewage Treatment System is designed for a Type 1 five -bedroom home in accordance with the <br />Minnesota Pollution Control Agency Chapter 7080 and local ordinances. <br />The periodically saturated soils were located at I8-22 inches (mottled soil). The existing mound system is <br />going to be used. <br />The existing septic system does conform to the state code chapter 7080 <br />All neighboring wells are greater than 100' from proposed treatment areas. <br />The soils at a depth of 12" have a percolation rate averaging 3 MPI. <br />The existing septic tanks must be abandoned. New septic tanks need to be installed that meets 2250 -gallon <br />septic tank capacity. <br />All new tanks need to be insulated if there is less than two feet of cover over the top of the tanks. Clean <br />outs must be installed on the end of the laterals for maintenance. <br />A 1300 gallon pumping chamber will need to be installed to lift the effluent to the treatment area. The <br />power supply and switches must be located outside the manhole and pumping chamber in a weatherproof <br />enclosure. A warning device must be installed with light and sound devices; this is in case of a pump <br />failure. A flow measurement device must be installed. Including but not limited to a water meter, event <br />counter, running time clocks or electronically controlled dosing. <br />With proper installation and maintenance, this system should have no problem in treating septic effluent <br />effectively. Nothing other than gray water. (laundry, showers, etc.) Human water and toilet tissue should be <br />disposed of into the septic tanks. Iron filters cannot go into the septic system Garbage disposals are not <br />recommended. Additives must not be used they may cause harmful damage to your septic system. It is <br />recommended that you pump the septic tanks every two years. <br />Sincerely, <br />Joseph J. Olson <br />
