NE, Hanover, MN 55341 <br /> (763) 498-8779 fag (763) 498-8290 <br /> Revised February 09,2007 <br /> Bruee Paddock <br /> Proposed Lot 1,Block 1 <br /> Tract C,RL.S.#843 <br /> Orono,Hennepin County <br /> This on-site Sewage Treatment System is partially designed for a Type 1,five-bedroom home in accordance <br /> with the Minnesota Pollution Contro(Agency Chapter 7080 and local ordinances. <br /> Once the house size, location and septic primary and future sites are chosen this design can be completed. <br /> The seasanally saturated soils were located at 14"-24"(mottled soil). Due to the seasonally saturated soils, <br /> a pressurized Mound System wil(need to be installed to treat septic effluent. The bottom of the treatment <br /> area must be located at least 3' above the satwated soils. <br /> The soils at a depth of 12"have a percolation rate averaging 22 MPI. <br /> A pumping chamber will need to be installed to lift the ef�luent 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 /> Keep all heavy equipment off of the 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 thac�gray water,(laundry,showers,ect.)human water&toilet tissue should be disposed of <br /> into the septic t�lnks. Garbage disposals are not recommended. Additives must no 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, <br /> ,� —� sEP'TtCITY C?F dR�NO� W <br /> �;-' tNSPECTUR �-���.1%1� 1��,�.; <br /> i � DATB-�.�PERMIT NQ. <br /> � Joseph J.Olson � A�P�VED�$�t7�;s,i}'rT���'. ...�. <br /> �xrf, ��, y� APPROV'�D V1►TfH CURRECTip�.�NpZ�p <br /> �O'f APPROYBD-CURRECT&xB�tBMJT <br /> t � ' ���+�e'a Pot yotir btforra�tiap.
