NE, Hanover, MN 55341 <br />(763) 498-8779 Fax (763) 498-8290 <br />November 7, 2017 <br />Norton Homes <br />680 Pinehurst Court <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 12-22 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 of 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 12 MPI. <br />A 2250 -gallon combination septic tank 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 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 />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. Additives must not be <br />used; they may cause harmful damage to your septic system. It is recommended that you pump the <br />tank every year for 1 septic tank, every two years for two septic tanks, <br />Sincerel r, <br />Joseph J. Olson <br />
