NE,Hanover,MN 55341 (763) 498-8779 Fax (763) 498-8290 May 11,2011 44 wn Road S.LLC. Pro osed Lo 445 Bro�vn oad S. 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 primary septic site are chosen this design can be completed. The periodically saturated soils were located at 16-28 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. Due to limited space.The mound rock bed must be split into two 32 foot rock beds.The absorption area of the proposed rystem does not overlap.A retaining wall will be needed to keep the side toe five fee[from the property line. This system is designed with duel rock beds usina non-level pressure distribution.See design sheets.Use 7/32 inch perforations on the laterals.See desien sheets. The soils at a depth of 12"have a percolation rate averaging 8 MPI. All neighboring wells are located gseater than 50'away from proposed treatment area 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 pumpiog chamber will need to be installed to lift the effluent to the treafinent 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 light and sound devices;this is in case of a pump failure.The manifold and supply line must have back drainage to the pumping chamber.The distribution pipes shall have their ends capped. Be sure the rock and sand fill materials are clean.The sod layer below the entire mounded area must be turned over,just break up the sod and be sure not to over work. Keep all heavy equipment off of the proposed treatment areas before,during and after construction With proper installation and maintenance,this system should have no problem in treating septic ei�luent effectively. Nothing other than gray water,(laundry,showers,etc.) Human water and toilet tissue should be disposed of into the septic tanks. Garbage disposals aze not recommended. Additives must not be used;they may cause hannful damage to your septic system. It is recommended that you pump tanks every two years.
