Joseph Olson D.B.A. <br /> Rusty Olson's--Soil and Percolation Testing <br /> Joseph J. Olson--MPCA License #810 <br /> 11481 Riverview Rd. NE, Hanover, MN 55341 <br /> (763) 498-8779 fax (763) 498-8290 <br /> May 11,201 I <br /> 44 oad S.LLC. <br /> roposed Lot 1 <br /> 44 rown oad S. <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 Poilution Control 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 seasonally saturated soils were located at 16"-24"(mottled soil). Due to the seasonally saturated soils, <br /> a presswized Mound System will need to be installed to treat septic ei�luent.The bottom of the treatment <br /> area must be located at least 3'above the saturated soils. <br /> The soils at a depth of 12"have a percolation rate averaging 8 MPI. <br /> A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply <br /> and 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 /> The existing tank must be abandoned.All tanks must be deeper than two feet below grade or they need to <br /> be insulated and as filter needs to be installed on the second tank. Clean outs must be installed on the end of <br /> the laterals for maintenance. <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 than gray water,(laundry,showers,ect.)human water&toilet tissue should be disposed of <br /> into the septic tanks. Garbage disposals are not recommended.Additives must not be used;they may <br /> cause harmful damage to your septic system. It is recommended that you pump the septic tanks every two <br /> years. <br /> ctT�oF oxoNo <br /> Sincerely, �IC F RM�� 1�►N K � — <br /> _ __ �3PECTU -�E..C.�C. <br /> __..__...._..-. �A �� - 1 � ��RMIT NO. <br /> �' ' APPROVED A9 5(.'BMITTEA <br /> �- Joseph J.Olson <br /> APPROV�D WITH C'l)RR�TIOKS AS 130T6p <br /> 1riOT APPAOVED�CORR6�'��RE9tiH1NtT <br /> ������� "�e�o�Ilnp{or�ipfqfmatioa..Ali work shull bc�Mru► <br /> ���► �� `������ «d��Usoot�hlt a114PPlicabla scp,tic and wning cuci�. <br /> ��W�W�1���RN�iY� 1(1W 1/f.�i11i�M ��IOOItNH�t10l1i6 AOt fj�CII�CYIIy i106C(i-lR Wli(CYf�� <br /> �7�4Pi�Ari�T�i ilT�t AT ALL TIlN6i <br />
