The monitoring set <br /> by LUG. <br /> The mitigation plan for this property is pressurized other mound system also the compacted soils dug out. <br /> A tank filter and cleanouts on the laterals will need to be installed. ORONO COPY <br /> A water meter will need to be installed in the house. <br /> A pumping chamber will need to be installed to lift the effluent 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 light and sound devices;this is in case of a pump failure.Keep all <br /> heavy equipment off of the proposed treatment areas before and after construction. <br /> Nothing other than gray water,(laundry,showers,etc.)human water and toilet tissue would be disposed of <br /> into the septic tanks. <br /> Since ely <br /> ORONO COPY CTry OF OR•NO <br /> SEPTIC P T P' '+ '1. <br /> I, <br /> Joseph J.Olson INSPECT / L - :►r`- <br /> DATE -)- di PERMIT NO.,....,,,.,.,,r,,,,,,_ <br /> APPROVED A9 SUBMITTED <br /> APPROVED WITH CORRECTIONS AS NOTES <br /> (I BEDNOT APPROVED.CORRECT*RESUBMIT <br /> ' Hese gab s t for front lnfbraxtiaa AU work siaxtl by done <br /> L t <br /> bEDRO011ialahla.""Alialt In full compliance with all applicable septic sad muting cede. <br /> Requirements Melodist;items apt specifically noted is Di"covimIN <br /> BEEP THU MAN UT aid$ITL AT ALL TAMU <br />
