NE,Hanover,MN 55341 <br /> (763) 498-8779 Fax(763) 498-8290 <br /> Pager(952) 980-8846 Digital <br /> September 11,2005 <br /> Scott Miller <br /> 85 S.Old Crystal Bay Road <br /> Orono,Hennepin County <br /> This on-site Sewage Treatment System is designed for a Type I,five-bedroom home in accordance with the Minnesota <br /> Pollution Control Agency Chapter 7080 and local ordinances. <br /> The seasonally saturated zone is present at 16"-22"(mottled soil). Due to seasonally saturated soils,a pressurized <br /> Mound System will need to be installed to treat septic effluent. The bottom of the treatment area must be located at <br /> least 3'above the saturated soils. <br /> All neighboring wells are greater than 100 feet from proposed treatment areas. <br /> The soils at a depth of 12"have a percolation rate averaging 7 MPI. <br /> The future site has duel rock beds.The rock beds meet the absorption area requirements. <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 <br /> warning device must be installed with light and sound devices;this is in case of a pump failure. <br /> Septic system should be fenced off 20' away from proposed and future systems before construction begins. <br /> Keep all heavy equipment off of the proposed treatment areas before,during and after construction. The area <br /> around both sites must be fenced off by the contractor before any construction begins. This Design is not valid <br /> and the System will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment <br /> occurs. <br /> Nothing other than gray water,(laundry,showers,etc.) Human water and toilet tissue should be disposed of into the <br /> septic tanks. Garbage disposals are not recommended. Additives must not be used;they may cause harmful damage to <br /> your septic system. It is recommended that you pump the tank every year for I tank every two years for two tanks. <br /> Sincerely, <br /> CITY OF ORONO Joseph J.Olson <br /> EPEC M&C Fes' <br /> '- <br /> DATE' D PERMIT <br /> APPROVEAl*VI3MITt'F.D <br /> APPROVED WITH CORRECTIONS AS NOTb <br /> win APPROVED•CORRECTA RESUBMIT <br /> cic soonest*ars for your informatics.
