Joseph J. Olson--MPCA License # 810 <br />11481 Riverview Rd. NE, Hanover, MN 55341 <br />3$ GPM Pump (763) 498-8779 Fax (763) 498-8290 <br />with 35# TDS <br />Revised July 16, 2018 <br />Chamberlin Capital . <br />2845 Lillian Lane I1 CY, <br />Orono, Hennepin County at <br />This on-site Sewage Treatment System is designed for a Type I 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 14-18 inches (mottled soil). Due to the periodically <br />saturated soils, a pressurized mound system with 6 inches of rock will need to be installed to treat the septic <br />effluent. The bottom of the treatment area must be located at least 3' above the saturated soils. This system <br />is designed with 6 inches or rock. <br />The future site is dual rock beds using gate valves for unlevel pressure distribution. <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 4 MPI. <br />A 2250 -gallon combination septic tank or it equivalent needs to be installed. <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 1250 -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. Garbage disposals are not recommended. Iron filters cannot go into the <br />system. 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 />
