NE, Haoover, MN 55341 <br /> (763) 498-8779 fag (763) 498-8290 <br /> January 15,2013 <br /> Ervin Wachman <br /> PID#0611723220018 <br /> Proposed Lot 2 <br /> Orono,Hennepin.County <br /> This on-site Sewage Treatment System is partially designed for a Type 1,five-bedroom home in <br /> accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. <br /> Once the house size, location and septic primary and future sites are chosen this desigr►can be completed. <br /> The periodically saturated soils were located at 16-18 lnches(mottled soil). Due to the periodically <br /> saturated soils,a pressurized mound system will need to be installed to treat the septic effluent.The bottom <br /> of the treatment area must be located at least 3' above the saturated soils. <br /> The soils at a depth of l2"have a percolation rate averaging 6.5 MPI. <br /> The absorption areas do not overlap. <br /> All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.A fi Iter needs <br /> to be installed on the second tank.Clean outs must 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 <br /> warning device must be installed with a light and sound device;this is in case of a pump failure. <br /> Use 7/32 inch perforations on the laterals. <br /> Keep all heavy eyuipment off of t6e proposed treatment areas before and after construction.The <br /> treatment area must be fenced off before construction begins.This Design is not valid &the System <br /> will need to be relocated if failure to protect the areas proposed for the On-Site Sewage Treatment <br /> systems occurs. <br /> Nothing other than gray water,(laundry,showers,ect.)human water&toilet rissue should be disposed of <br /> into the septic tanks. Garbage disposals are not recommended.Additives must not be used;they may cause <br /> harmful damage to your septic system. It is recommended that you pump the septic tank every year for 1 <br /> tank,every two years for two tanks. <br /> sincerely, �"�'�' �F O ONQ <br /> �� 5EPTIC PE IT P _REV <br /> _._----- <br /> �eph J.Olson INSPECT��Rc <br /> DATE '' ' 3 PBRMIT NO.�,,,.,.,�,,,,,,...,�., <br /> APPRQYGA AS St;ii�t(TTEU <br /> APPROYGD WITH CORRF:CTIONS AS nOTBD <br /> NOT AFPROYF:U•CURRF.CT&RF:5L'HMIT � <br /> 'Thcsc eommentc are for your information.
