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