The ductile iron pipe will protect the sewer line from being crushed <br /> and the styrofoam insulation will protect it from freezing. We had done a survey of the property <br /> for you in 1999 and Eco Systems Engineering has designed an on site sewage treatment system <br /> for you. The Eco Systems Engineering drawi.ng shows the location of the proposed crossing. <br /> This is to certify that this plan was prepared by me or tmder my direct supervi.sion and that I am� <br /> licensed Professional Engineer under the laws of the Sta.te of�1i.nnesota. <br /> Sincerely, <br /> ADVANCE SURVEYIl�tG GINEERING CO. <br /> ` <br /> Jam H.Parker P.E. &P.S.No. 9235,President <br /> cTT� oF o RON o <br /> SEPTIC PERMIT�;,'� REVIEW <br /> T�,T�P F C TnR ��T'< < �.�---- <br /> t�,�;-r �-�-e3 PF,RMITNO.,,.._......�.-.--- <br /> � , ,�: �, i��,�rr-rr.o <br /> ; 11 � _ . ,.' ����iCl`�'S AS 1vOTED <br /> [._ " ' ` , , �<<'R�AIT � <br /> � .t�1 -� ���, , !'�i,cdone <br /> ,�.c !��,� �.. _ �i�i�� � <br /> Tl�c,c cuni;,�,•;! � , �i ��I��. <br /> in full cumpliancc �euii a,'. r.,�..�..: � ` � ;.,� rw. <br /> Rccluircments inclu�ling i,cm�;�.:.�,V� � �_ r ��� _.�,. <br /> REEP THIS PLAN SL"I Uh 5l"I l.A l :�LL I i`.t�,� <br />
