The periodically saturated soils were located <br /> at26" & 34"(redox features). Due to the seasonally saturated soils, a Pressurized <br /> Mound System will need to be installed to treat septic effluent. The bottom of the rock <br /> must be located at least 3' above the saturated soils. <br /> ORONO COPY <br /> The existing 2-1000 gallan septic tanks may be used upon a Tank Integrity Report <br /> certifying the tanks. If the tanks need to be replaced, install 2-1000 gallon septic tanks <br /> & a new 1000 gallon pumping chamber. The tanks will be abandoned, pumped &filled <br /> with soil. <br /> The soils at a depth of 12" have a percolation rate of 15.0 mpi. <br /> A pumping chamber will need to be installed to lift the effiuent to the treatment area. <br /> The power supply and switches must be located outside the manhole and pumping <br /> chamber in a weather proof enclosure. A warning device must be installed with a light <br /> and sound device, this is in case of a pump failure. <br /> The manifold and supply line pipe must have back drainage to the pumping chamber. <br /> The distribution pipes shall have their ends capped. Be sure the rock and sand fill <br /> material are clean. The sod layer below the entire mounded area must be turned over, <br /> just break up the sod, be sure not to over work. <br /> ORON�GOPY ��,������� <br /> + � � ����q���� <br />
