NE, Hanover, MN 55341 <br /> (763) 498-8779 Fax (763) 498-8290 <br /> September 4,2015 <br /> Patrick Doherty <br /> 2790 White Oak Circle <br /> Orono,Hennepin County <br /> This on-site Sewage Treatment System is designed for a Type l four-bedroom home in accordance with the <br /> Minnesota Pollution Control Agency Chapter 7080 and local ordinances. <br /> The periodically saturated soils were located at 14-24 inches(mottled soil). Due to the periodically saturated <br /> soils,a pressurized mound system will need to be installed to treat the septic effluent. The bottom of the <br /> treatment area must be located at least 3' above the saturated soils. <br /> The existing septic system does not 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 3.6 MPI. <br /> The existing septic tanks must be abandoned and a minimum two new 1300 gallon and 1000 septic tanks <br /> need 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 outs <br /> must be installed on the end of the laterals for maintenance. <br /> A 1000 gallon pumping chamber will need to be installed to lift the effluent to the treatment area.The power <br /> supply and switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. <br /> A warning device must be installed with light and sound devices;this is in case of a pump failure. A flow <br /> measurement device must be installed.Including but not limited to a water meter,event counter,running time <br /> 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 two years for two septic tanks. <br /> Sincere] ', <br /> CITY OF ORONO��� <br /> SEPTIC PE IT PLAIy;R�. iIEW <br /> I�'SPI CTOR cry, <br /> Joseph J.
