The periodically saturated soils were locateci at <br /> 16" to 22" (r�dox features). Due to the seasonally saturated soils, a Pressurized <br /> Mound System will need to be installed to treat �eptic effluent. The bottom of the rock <br /> must be located at least 3' above the saturated soils. <br /> 01tON0 COPY <br /> The downslope toe of the mound will extend into an easement owned by the City of <br /> Orono. This will require an Easement Agreement between the owners of the praperty & <br /> City. The encroachment into the easement is needed due to limited space & drainage <br /> pattern. An agreement will also be needed between the praperty owners for a shared <br /> system, land, maintenance, electric, etc. ��������� <br /> ,�B��RooMs. ���t��t�tr�� <br /> The soils at a depth of 12" have a percolation rate of 10.9 mpi.������DATES��t$DESIGN. <br /> 630 has no septic tanks at this time. 640 has 1 possible tank (shown on the sifie plan) a <br /> tank was not found. The supply line will need to be exposed & excavated to the tank. <br /> The tank will need to be abandoned, pumped & filled with soil. If the tank is only a <br /> small barell etc., the Inspector will need to determine how to abandon. <br /> Each property will have 2-1000 gallon Norwesco Bruiser tanks installed which will flow <br /> to a 1000 gallon pumping chamber which with a timer pumping to the mound system. <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 /> � ORONO C4PY <br />
