Due to seasonally saturated soils,a pressurized <br /> Mound System will need to be installed to treat septic efiluent. The bottom oFthe treatment area must be located at <br /> least 3'above the saturated soils. <br /> The soils at a depth of 12"have a percolation rate averaging 3 MPI. <br /> ALl neighboring wel ls are located greater than 100'away&om proposed treatment area. <br /> 1'he existing septic tank may be used upon approval of the local inspector. <br /> The existing system does not conForm to chapter 7080. <br /> A pumping chamber will need to be installed to lift the efEluent to the treatment area. The power supply and switches <br /> must be located outside the manhole and pumping chamber in a weathecproof enclosure. A warning device must be <br /> installed with light and sound devices;this is in case of a pump failure. <br /> The manifold and supply line must have back drainage to the pumping chamber. The distribution pipes shall have their <br /> ends capped. Be sure the rock and sand fill materials are clean. The sod layer below the entire mounded area must be <br /> tumed over,just break up the sod and be sure not to over work. <br /> Keea s116eavv eauiament off of the proposed treatment area before during and after construction. This Desien <br /> is not valid and the Svstem will need to be relocated if failure to orotect the area aroposed for On-Site Sewage <br /> Treatment occurs. <br /> With proper installation and maintenance,this system should have no problem in treating septic eftluent ef�ectively. <br /> Nothing other than gray water,(laundry,showers,etc.) Human water and toilet tissue should be disposed of into the <br /> septic tanks. Garbage disposals are not recommended. Additives must not be used;they may cause harmful damage to <br /> your septic system. It is recommended that you pump the tank every year for 1 tank every two years for two tanks. <br /> Sincerely, <br /> �� �-1 CtTY OF ORONO <br /> / SEPTIC���,�'L�N REV�I� <br /> � �' INSPECTOR " �' — <br /> � Joseph J.Olson DAT � � ' ERMIT NO.�-- <br /> APPROVF.D AS SL'B�t[TTLU <br /> [� APPROVF.D W�TH Cc�RRGCTIO?�S AS NOTF.D <br /> Q 1:OT APPROVEI)-CC�RRF,CT&RF.SliA�11T <br /> Thcse comments ace for your�forbi`���tic undLio�inL,�hv done <br /> in fuU compliancc with all a�� <br /> Rcquircmcnts inc:luding itcros not spccilically n����'d in this rcview. <br /> KiiCP TH(S PLhi�SF•."C OK SITE AT ALL 71�11iS <br />
