NE,Hanover,MN 55341 <br /> (763)498-8779 Fax(763)498-8290 <br /> Revised February 4,2014 <br /> September 22,2011 <br /> Jeff&Paula Bata <br /> 2360 Willow Drive <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 24-28 inches(mottled soil).Due to The periodically saturated <br /> soils,a pressurized Mound System will need to be installed to treat septic effluent.The bottom of the <br /> 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 3 MPI. <br /> All neighboring wells are located greater than 100'away from proposed treatment area. <br /> A lift pump will need to be installed in the lowest level to keep the tanks 50 feet from the wetland. <br /> All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.Clean outs must <br /> be installed on the end of the laterals for maintenance. <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 warning <br /> device must be installed with light and sound devices;this is in case of a pump failure. The manifold and <br /> supply line must have back drainage to the pumping chamber. <br /> Keep all heavy equipment off of the proposed treatment areas before,during and after construction. <br /> The area around both sites must be fenced off by the contractor before any construction begins.This <br /> Design is not valid and the System will need to be relocated if failure to protect the areas proposed for <br /> On-Site Sewage Treatment occurs. <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.Additives must not be used;they <br /> may cause harmful damage to your septic system.It is recommended that you pump the tanks every two years <br /> Sincerely, <br /> e <br /> Joseph J.Olson <br />
