NE, Hanover, MN 55341 (763) 498-8779 fax (763) 498-8290 January 15,2013 Ervin Wachman PID#0611723220018 Proposed Lotl Orono,Hennepin.County This on-site Sewage Treatment System is partially designed for a Type 1,five-bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. Once the house size,location and septic primary and future sites are chosen this design can be completed. The periodically saturated soils were located at 20-28 Inches(mottled soil).Due to the periodically saturated soils,a pressurized mound system will need to be installed to treat the septic effluent.The bottom of the treatment area must be located at least 3' above the saturated soils. The soils at a depth of 12"have a percolation rate averaging 6.4 MPI. The absorption areas are greater than 50 feet from the wetlands. All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.A filter needs to be installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance. A pumping chamber will need to be installed to lift the effluent to the treatment area.The power supply and switches must be located outside the manhole and pumping chamber in a weatherproof enclosure.A warning device must be installed with a light and sound device;this is in case of a pump failure. Use 7/32 inch aerforations on the laterals. Keep all heavy equipment off of the proposed treatment areas before and after construction.The treatment area must be fenced off before construction begins.This Design is not valid&the System will need to be relocated if failure to protect the areas proposed for the On-Site Sewage Treatment systems occurs. Nothing other than gray water,(laundry,showers,ect.)human water&toilet rissue should be disposed of into the septic tanks.Garbage disposals are not recommended.Additives must not be used;they may cause harmful damage to your septic systern. It is recommended that you pump the septic tank every year for 1 tank,every two years for two tanks.
